A customer asked if we could put two SP8T switches in one box with USB control.

We did.

2 inputs, 16 outputs, DC to 40GHz, 2.92mm connectors. Latching, 2M cycle life. GUI + API for Windows and Linux.

It's been going into ATE systems and defense labs mostly. Saves a lot of cable swapping.

Specs in the comments. Happy to answer questions.

Trade vs. Manufacturer: how do you know the difference?

Anyone can sell you an RF cable. The question is—who actually makes it?

Here's what a real factory looks like:

🏭 Automated crimping press in-house
→ Calibrated force on every connector, not hand-tightened

🔧 Strain relief integrated at the assembly stage
→ Designed in, not added as an afterthought

📊 100% electrical testing before shipping
→ Insertion loss + VSWR verified on every unit

This is our production floor. No stock footage. No renders.

ZOMWAVE is a manufacturer, not a trading company. 20+ years of RF & microwave component production under one roof.

If you're sourcing cable assemblies or RF components, you're welcome to verify us—samples, factory audit, video call, whatever makes you comfortable.

Quick intro to what we do at ZOMWAVE.

Core product lines: RF switches, cable assemblies, power dividers, directional couplers, adapters, connectors, and attenuators. Basically the building blocks for most RF test systems and communication chains.

We're not a trading company. We manufacture in‑house — design, machining, assembly, testing, all under one roof. ISO 9001 certified. 40,000+ components in stock. 5‑day lead time on most orders.

If it goes in an RF signal chain, there's a good chance we make something for it.

This is the 30dB coupler I mentioned in that post about PA testing a couple weeks back.

CPD30DB-SMA | 0.5‑8GHz | 30W | SMA female

High‑power PA monitoring (50W+). Coupled port taps just enough signal for your power meter or spectrum analyzer. Won't fry the front end, won't load down the line.

We stock these. 5‑day lead time.

Your SPDT switch is fine in the lab. Put it in a moving vehicle? That's where most of them fall apart.

Vibration. Thermal cycling. Connectors that work themselves loose after a few hundred miles. If you're doing RF testing in automotive environments, you've probably run into this.

We built this SPDT switch for exactly that scenario.

Two things that actually matter in a moving vehicle:

🔌 SMA, rated for high power across the band. Not just at 1GHz — where it matters. This one handles 100W CW at 18GHz. Radar, V2X, 5G automotive tests — the switch won't be the weak link.

🔗 JST PAD 2.0 automotive-grade connector. Most RF switches use solder pins or D-SUB for control. Fine for a bench. Not fine for a test rack that gets bounced around. This one is keyed, locking, and field-replaceable. Same class of connector used in engine control units. It stays put.

Quick specs:

📡 DC – 18 GHz, 50Ω, SMA female
⚡ 100W CW at 18GHz / 200W peak
🔁 Latching, 24V (12V / 28V on request)
⏳ 2 million cycle operating life
🔧 JST PAD 2.0 control connector (automotive grade)

If you've ever had a switch fail in a moving test vehicle, you know exactly why we built it this way.

📊 SP8T Switch Selection — What the First Page of the Datasheet Won't Tell You

Just helped a customer compare a few SP8T switches. Here's what jumped out at me:
Every datasheet looks good at 6GHz. Push it to 40GHz — the gaps show up fast.

Insertion loss across the band: 0.10dB at 3GHz, 0.41dB at 18GHz, and still only 0.71dB at 40GHz. That last number is where a lot of competing switches start to drift.

The number I always check first? Isolation.
96dB at 3GHz. 75dB at 40GHz. That isolation at the band edge is what actually keeps your system stable. A lot of engineers get burned because they only check the mid-band numbers.

Personally, I always look at the high-frequency data first. The low-frequency numbers are rarely the problem.

What do you check first when evaluating a switch?

30/07/2026

36 seconds. From parts to finished switch.

No CGI. No render farms. Just our bench.

Two places where cheap switches fail:

Housing alignment.
We fixture every housing in place. Others eyeball it.
Guess whose VSWR drifts after a temperature cycle?

Torque spec.
Not "tight enough." Not "by feel."
Calibrated torque wrench, logged value, every unit.

Do these two right, and 1M cycles is the baseline.

SMA, 2.4mm, 2.92mm — we'll put whatever connector you need on it. SP3T up to SP12T. Sample run from 5 pcs.

Behind every switch is an ISO 9001:2015-certified factory, 40,000+ components in stock, and a team that actually builds what we sell. Shenzhen + Penang manufacturing.

Got a specific requirement? Drop "SPECS" in the comments or DM me. I'll send the datasheet.

RF engineer here. After 20+ years, this is the comparison I still show new guys:

Between resistive and Wilkinson power dividers, I look at three things: bandwidth, insertion loss, and isolation.

Resistive gives you DC to 67 GHz, but you pay for it — 6dB loss on a 2‑way, low isolation, and only handles about 5W. Wilkinson is narrower (usually 0.01‑40 GHz), but you get 18‑20dB isolation, 0.5‑1.5dB loss, and handles up to 30W. Trade‑off is always bandwidth vs performance.

Three scenarios I see all the time:

• 28 GHz mmWave distribution? Resistive wins.

• MIMO channel emulation? Wilkinson — non-negotiable.

• Lab reference level distribution? Wilkinson, every time.

We make both, and we'll custom‑build whatever you need.

If you're working on similar stuff, I'd be curious what you usually go with — resistive or Wilkinson? Drop it below.

📊 How to read RF switch test curves

Ever compared switches from different vendors? Specs match, but performance doesn't.

I check two things first: loss flatness across the whole band (not just one frequency), and isolation at the band edges (not just mid‑band). Most datasheets look great at 6GHz, fall apart at 40GHz.

The plots below are from an SP6T we recently characterized. DC to 40GHz, SMA, calibrated VNA.

I always end up caring most about isolation. What about you?

22/07/2026

5‑day lead time. That's not marketing. That's just how we work.

Semi‑rigid, RG, custom lengths, weird connectors – we do it all. Ship it fast, test it first.
