For a 5G RF filter and front end designed in Malaysia, Walsin Technology (Walsin) lists 156 RF parts for cellular use, and 4 of them cover the 3,300 to 3,800 MHz range: a 1608 low-pass filter, a 1608 balun and two antenna switches. Venatech, Walsin’s authorised distributor in Hong Kong, crosses your RF parts to them free.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for an RF engineer in Kuala Lumpur or the Klang Valley designing a 5G customer-premises router, a small cell or a cellular IoT module, who needs filters, baluns, couplers and switches in small packages. We parsed the eight Walsin RF export files in our data folder (457 distinct part numbers), including Walsin_Filter.xlsx, Walsin_Balun.xlsx, Walsin_Multiplexer.xlsx and Walsin_Antenna_Switch.xlsx, and checked our stock list as at 23 September 2026. We re-measured every count on 11 November 2026.
What did Opensignal report about 5G in Kuala Lumpur?
Faster 5G and a second network. According to Opensignal’s Malaysia mobile network experience report of July 2026, covering 1 April to 29 June 2026, U Mobile users in Kuala Lumpur saw 5G download speeds of 271.1 Mbps and 75.7 percent 5G availability, the highest of the five operators measured in the city.
The same report says U Mobile completed its move to its own 5G network in July 2026, exited its wholesale agreement with DNB and now runs Malaysia’s second 5G wholesale network. Nationally, it measured U Mobile’s 5G download speed at 280.4 Mbps and 5G availability at 66.6 percent. Those are Opensignal’s figures, not ours. Our conclusion: two 5G networks mean more radios, more routers and more modules designed and built around Kuala Lumpur, and each needs RF front-end parts. We have no relationship with any operator and say nothing about what one buys.
How many Walsin RF parts are made for cellular use?
156 of 457. We counted 156 Walsin RF part numbers whose application field names 2G, 3G, 4G, 5G, LTE or 5G NR use, or that are BAW or SAW cellular filters: 70 filters, 33 baluns, 24 multiplexers, 13 couplers, 8 antenna switches, 5 BAW and 3 SAW parts.
The rest of the 457 serve 2.4 GHz and 5 GHz Wi-Fi, Bluetooth, MoCA, GNSS and automotive links, which a Malaysian CPE often needs on the same board. So one Walsin catalogue can cover many of the passive RF positions on a 5G router. The Walsin RF range lists the families, and our overview of Walsin RF baluns, filters, couplers and multiplexers describes each type.
Which Walsin RF parts cover a 3,300 to 3,800 MHz 5G path?
Four do. We read the frequency fields of all 457 RF parts and found 4 that cover the full 3,300 to 3,800 MHz range or a band inside it: RFLPF16083G5W7T, RBBLN16083G6W0T, RFASWB022ATF0E and RFASWA630PTF0E.
The table sets them against a brief of a 5G path inside 3,300 to 3,800 MHz, and adds two 2.5 to 2.7 GHz parts for an LTE path on the same board. Your incumbent goes in the last column.
| Walsin part | Type | Size | Frequency in the export | Key figure in the export | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|---|---|
RFLPF16083G5W7T |
Low-pass filter | 1608 | 3,300 to 3,800 MHz | 0.55 dB insertion loss | Match | |
RBBLN16083G6W0T |
Balun | 1608 | 3,550 to 3,700 MHz | 5G (generation) application | Match inside 3,550 to 3,700 MHz only | |
RFASWB022ATF0E |
DPDT antenna switch | 1.5 x 1.1 mm | 617 to 5,000 MHz | 29 dB min isolation at 3,300 to 3,800 MHz | Match | |
RFASWA630PTF0E |
SPDT antenna switch | 1.1 x 0.7 mm | 100 to 6,000 MHz | 20 dB min isolation at 3,000 to 3,800 MHz | Match | |
RFLPF16082G5W0T |
Low-pass filter | 1608 | 2,300 to 2,700 MHz | 0.9 dB insertion loss | Mismatch: LTE band, below 3,300 MHz | |
BA11092593B41E1T |
BAW filter | 1109 | 2,496 to 2,690 MHz | single BAW filter | Mismatch: LTE band, below 3,300 MHz |
A match is a match on the export’s frequency field. Insertion loss, rejection and power handling at your exact channel must come from Walsin’s datasheet and from your own measurement.
What should a Kuala Lumpur RF team check beyond the frequency field?
Rejection, power and layout. For the 4 mid-band parts in our table, the export gives frequency and one loss or isolation figure each; out-of-band rejection, maximum input power and the recommended land pattern come from Walsin’s own datasheet, which we request for any part you shortlist.
A low-pass filter after a power amplifier must reject harmonics, so its attenuation at twice and three times the carrier matters more than its passband loss. A balun must match the differential impedance of your transceiver. A switch must carry your transmit power with margin. Our guide to choosing an RF chip filter by band and our page on Walsin RF front-end switches, BAW, SAW and multiplexers cover both checks.
How do you get Walsin RF parts through Venatech?
Request a quote. All 457 Walsin RF part numbers we counted can be quoted through Venatech; for RF parts, request a quote and we source them through our authorised Walsin channel rather than from our 23 September 2026 Hong Kong snapshot.
RF parts are often bought in small engineering quantities first and production reels later, which suits a Hong Kong distributor that quotes small lots. The ready-stock list is a dated snapshot, never live-synced; we give no lead time or stock promise.
What will we not tell you about a Malaysian 5G product?
Which bands your product must cover, or how to certify it. Our counts cover catalogue coverage only: 156 cellular RF parts and 4 that reach 3,300 to 3,800 MHz; none of it says which bands your customer or operator requires.
Band plans, power classes and type approval are set by the operator and the regulator, so take them from your customer and your certification lab. We hold no office or entity in Malaysia; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or radio-approval advice; confirm with your compliance team.
How Venatech helps: what should a 5G hardware team in Kuala Lumpur send us?
Your RF front-end lines from any maker. Venatech is Walsin’s authorised distributor in Hong Kong, and VenaMatch decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, with every difference stated.
Paste up to 500 part numbers into the free cross-reference tool, or upload a BOM with your band list and request a quote. Worked example from our own export: a 3,300 to 3,800 MHz brief returned a 1608 low-pass filter, a 1608 balun and two antenna switches. Walsin is the line we are authorised for; Stackpole and Viking are lines we supply. Small lots and fast quotes from Hong Kong.
