The Walsin antenna connector data contradicts its own series name. Dipole Antenna (N, SMA) holds 7 parts and 0 of them carry an N connector; 4 of the 7 are Reverse SMA. We read all 44 rows: a two-letter code inside the part number names the connector correctly on 20 of 20 rows that have one.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Series, Connector 1 and Connector 2 columns of Walsin_Antenna_ALL.xlsx, the antenna export from Walsin Technology (Walsin). This post is written from those columns and from the part numbers themselves, and nothing else. We hold no datasheet for any antenna, so no connector below is checked against a drawing. Every part number is real and sits in Walsin’s own export. The question is the one a buyer asks before the first purchase order: if the series says SMA, is the part SMA?
What connectors do the Walsin antenna series actually hold?
Seven distinct connector strings across ten series. We counted the Connector 1 column on all 44 rows: 28 are filled and 16 blank, with 7 distinct strings. Connector 2 is filled on 6 rows only, all of them cable assemblies or connectors. The series name and the connector cell agree on most series and disagree on one.
| Series | Parts | Connector 1 found |
A real part | Match / mismatch against the series name |
|---|---|---|---|---|
| Chip Antenna (BT, Wifi BAND) | 12 | blank on all 12 | RFANT3216120A1T |
Match — a surface-mount chip has no connector; 2 of 12 reach a 5 GHz band |
| Dipole Antenna (N, SMA) | 7 | SMA 2, Standard SMA 1, Reverse SMA 4 | RFDPA191300SMBB801 |
Mismatch — no N connector on any of the 7 |
| Dipole Antenna (Cable) | 6 | IPEX 6 | RFDPA131012IMTB301 |
Match — all 6 terminate in IPEX |
| PCB Antenna | 6 | IPEX 4, Strip & Tin 2 | RFPCA460605NNAB301 |
Match — a bare tinned lead on two |
| FPC Antenna | 3 | IPEX 3 | RFFPA202506IMAB301 |
Match |
| Metal Antenna | 2 | blank | RFMTA010504NNRB002 |
Match — no connector |
| NFC and WPC coils | 1 and 1 | blank | RFNFC355500NNNB001 |
Match — a coil |
| Cable Assembly | 3 | Strip & Tin, IPEX, N JACK | RFCBA241530AF6B601 |
Match on the series, but this is where the only N sits |
| Connector | 3 | MMCX, SMA, SMA | RFCON161202SA6B001 |
Match — a connector, not an antenna |
The row that matters is the second one. We have not seen this contradiction counted anywhere.
Does the series named (N, SMA) contain any N connector?
No. Not once in 7 parts. We read Connector 1 on every Dipole Antenna (N, SMA) row: SMA on 2, Standard SMA on 1, Reverse SMA on 4, and N on none. The only N connector anywhere in the 44-row file is an N JACK on the cable assembly RFCBA241530AF6B601, a 300 mm part that is not an antenna.
The series name is a label for a family of long external dipoles. It is not a list of the connectors on the parts inside. A buyer who filters the series name for “N” expecting a 50-ohm N-type dipole finds a family that is entirely SMA-family, and a buyer who filters Connector 1 for “N” gets one row, a cable.
| Part | Connector 1 | Band | Body as published | Match / mismatch against a request for an N connector |
|---|---|---|---|---|
RFDPA141300SMGB701 |
SMA | 1565 to 1606 MHz | 171.8 x Ø13 x 18 mm | Mismatch — SMA family |
RFDPA660900SMTB801 |
Standard SMA | 700±50 MHz | 75 x Ø10 mm | Mismatch — SMA family |
RFDPA191300SBAB803 |
Reverse SMA | 2.4 GHz | 196.6 x Ø13 x 13 mm | Mismatch — SMA family, reverse |
RFCBA241530AF6B601 |
N JACK | DC to 6 GHz | 300 x 25.25 x 25.25 mm | Match on connector, mismatch on part type — a cable assembly |
Is Reverse SMA the same connector as SMA in the Walsin export?
The export treats them as three different strings, and 4 of the 7 dipoles are the Reverse one. We counted every SMA-family cell in the antenna file: SMA on 4 rows, Reverse SMA on 4, Standard SMA on 1, nine rows in all. A filter for the exact string SMA returns 4 rows, and 2 of those are connectors rather than antennas. A filter for any cell containing “SMA” returns 9 and mixes the Reverse parts in with the rest.
Two parts share one body and differ only in the connector. RFDPA191300SMBB801 is published as SMA at 840 to 868 MHz, and RFDPA191300SBAB803 as Reverse SMA at 2.4 GHz. Both read 196.6 mm x Ø13 mm x 13 mm. The part numbers differ in two places, the connector code and the band letter, and the Connector 1 cell differs in one word.
Can the Walsin part number tell you the connector?
Yes, for the rows that have one, and it never contradicted the column. We compared characters 12 and 13 of each part number with Connector 1 on the 38 antennas. Three codes, IM, SM and SB, cover 20 rows, and the connector cell agrees with the code on 20 of 20. IM is IPEX on 13 rows, SM is SMA or Standard SMA on 3, SB is Reverse SMA on 4.
| Code at characters 12 and 13 | Rows | Connector 1 |
Agrees with the code | Match / mismatch |
|---|---|---|---|---|
| IM | 13 | IPEX on 13 | 13 of 13 | Match |
| SM | 3 | SMA 2, Standard SMA 1 | 3 of 3 | Match on family, mismatch on spelling |
| SB | 4 | Reverse SMA 4 | 4 of 4 | Match |
| NN | 6 | blank 4, Strip & Tin 2 | split 4 and 2 | Mismatch — one code, two states |
| 0A, 0L, 1A | 12 | blank 12 | n/a | Mismatch — a chip field, not a connector |
The code settles which dipole series a part belongs to. All 13 RFDPA parts split exactly: the 7 coded SM or SB sit in Dipole Antenna (N, SMA) and the 6 coded IM in Dipole Antenna (Cable). The code is not safe everywhere. NN appears on 4 rows with a blank connector, the two metal antennas and the two coils, and on 2 PCB antennas that end in a tinned lead. A script that reads NN as “no connector” misreads two parts, RFPCA460605NNAB301 and RFPCA501019NNAB301. On the cable and connector rows SA and SF both give SMA, so the code is finer than the column there. For how a whole part number decodes, see how to read a Walsin MLCC part number, which shows the same logic on a different line.
How should you filter Walsin antennas by connector?
On Connector 1 first, on the part number second, and never on the series name. Filter the column, then confirm with characters 12 and 13: an SM, SB or IM code that agrees with the cell is as close to a double check as this export gives you. Exclude the three cable assemblies and three connectors by Series before you count anything.
For the other columns beside the connector, see Walsin antenna specification fields: 4 of 10 are filled on all 44 parts. Three further rules come from the counts above. Treat SMA, Standard SMA and Reverse SMA as three values until a datasheet says otherwise. Treat NN as “check the cell”. Treat a blank Connector 1 as no connector only on a chip, metal antenna or coil, which is 16 of the 38. Our free cross-reference tool states differences from your original rather than hiding them behind a tick, and the antenna range lists all 44 rows.
We checked the 1,125 part numbers in the ready-stock snapshot dated 23 September 2026 against all 44 antenna part numbers: none appears, so these are enquiry items. See ready stock for what is held. We hold 28 Walsin datasheets, 451 pages, and none covers antennas. Qualification stays with you.
The short version
Walsin’s Dipole Antenna (N, SMA) series holds 7 parts and no N connector. The connector cells read SMA on 2, Standard SMA on 1 and Reverse SMA on 4. The only N in the 44-row file is an N JACK on the cable assembly RFCBA241530AF6B601. A two-letter code at characters 12 and 13 of the part number agrees with Connector 1 on 20 of 20 rows that carry IM, SM or SB, and splits the 13 dipoles exactly into their two series. The NN code is ambiguous: blank on 4 rows, a tinned lead on 2. We will not tell you a connector matches. We will show you the cell the file holds. Confirm against both datasheets and qualify in your own circuit.
Send us the dipole you use today and the connector on your cable and we will show you what the file says about each. And a question back: when a series name says N, how many of your last antenna orders were checked against the connector cell?
Frequently asked questions
Does Walsin offer an N connector dipole antenna?
Not in the export we hold. The series named Dipole Antenna (N, SMA) has 7 parts and none shows an N connector; the cells read SMA on 2, Standard SMA on 1 and Reverse SMA on 4. The only N connector in the 44-row file is a jack on a cable assembly, not an antenna. We hold no antenna datasheet.
Are Reverse SMA and SMA the same Walsin connector?
The export writes them as different strings: SMA on 4 rows, Reverse SMA on 4 and Standard SMA on 1. Four of the 7 dipoles in the SMA series are Reverse SMA. How they mate is not stated in any document we hold, so confirm gender and polarity against Walsin’s specification before ordering a cable.
What do the letters in a Walsin antenna part number mean?
Characters 12 and 13 name the connector on dipole, PCB and FPC antennas. IM agrees with IPEX on 13 of 13 rows, SM with SMA or Standard SMA on 3 of 3, and SB with Reverse SMA on 4 of 4. NN is ambiguous, with a blank connector on 4 rows and a tinned lead on 2.
How many Walsin antennas have no connector listed?
Sixteen of the 38 true antennas have a blank Connector 1 cell: 12 chip antennas, 2 metal antennas, 1 NFC coil and 1 wireless power coil. For those 16 blank means no connector. The other 22 carry IPEX on 13, Reverse SMA on 4, SMA on 2, Strip and Tin on 2, and Standard SMA on 1.
Can I filter the Walsin antenna range by series name to get a connector type?
No. The series name Dipole Antenna (N, SMA) lists a connector that appears on none of its seven parts, and Chip Antenna (BT, Wifi BAND) holds twelve parts with no connector at all. Filter the Connector 1 column and check characters 12 and 13 of the part number.
Are the Walsin antennas in the ready-stock list?
Not as at 23 September 2026. We checked all 44 antenna part numbers against the 1,125 part numbers in the snapshot and none appears. These lines are available on enquiry, and the snapshot is a dated list, not a live feed. Send us your part numbers and we will tell you what we can supply.
