Powering the Future
of Frequency

We make the state of the art RF components including transformers, splitters and combiners that transform the capabilities and longevity of any solid-state amplifier.

Components that Drive Greater Capability
and Competitive Advantage

An amplifier is greater than the sum of its parts. It can also be limited by them. What goes inside sets the ceiling on how much it can do and how long it holds up, and that ceiling is the difference between just meeting your customer's spec and beating everything and every competitor on their list.

Precision-Engineered Performance

Low insertion loss, tight matching, and power handling that holds up under load. That is how an amplifier gives you everything it was built to give, year after year.

Accelerating Innovation

Most of our work is custom. Stop designing around a part that almost fits and you can build the amplifier you actually wanted, on the schedule you had.

Value Without Compromise

We do the design and the manufacturing ourselves. That keeps the price under what traditional suppliers quote, with nobody adding margin on the way to you.

Engineering edge

The impedances nobody else stocks.

Most catalogs stop at 50 ohms. We've spent thirty years building into 5, 12.5, 25, and whatever else the topology called for. Get the match right at those numbers and the amplifier runs harder and lives longer. Tell us your number and we'll build into it.

Where our components live on the spectrum

Four families covering 1 to 300 MHz. Find your frequency, then find the part that changes what the amplifier around it can do.

Quality & reliability

Built to hold up. So is what you connect it to.

A match that drifts sends power straight back into the devices that made it, and that is how amplifiers die early. So we use the same materials and the same workmanship on a run of one as on a run of ten thousand. And we spend as much time on what happens when a part fails as on what happens when it works.

Insulation

TFE insulated wire, standard

Pre-wired versions come with TFE insulation and we don't charge extra for it. It's there so the winding survives the heat, which is the only good reason to specify it.

Failure mode

It keeps running when an amplifier dies

Every combiner has provisions for power balancing resistors. Fit them and a dead amplifier just drops you to reduced power. Leave them out and your output goes to zero. We build in the option either way.

Thermal

Heat sink versions where it counts

All-metal heat sink construction is available across the high-power line. If your duty cycle is hard on ferrite, say so when you order and we'll build it that way.

Specification

These are guaranteed numbers

30 dB minimum isolation between splitter output and combiner input ports. VSWR under 2:1 from 2 to 20 MHz, guaranteed. Those are floors we hold to on every unit.

MTBF
Mean time between failures Reserved for the real MTBF number and how it was measured: hours, conditions, sample size, and which standard.
Why RFPS

Why engineers call us.

01

30+ years of design files

Odds are your requirement maps to something we've already built and tested. That saves you a design cycle before it ever saves you money.

02

Nonstandard impedance expertise

5, 12.5, 25 ohms, and the numbers in between. These are the environments the off-the-shelf catalog skips entirely.

03

Custom is the default

Send a drawing and a requirement. Special orders to customer spec are normal work here. They don't go through an exception queue.

04

No ITAR or EAR restrictions

Our components carry no export control burden, so international orders move as fast as the freight does. No licence to wait on.

05

Sold direct, domestic and international

No distributor tier and no third-party fees on your BOM. You talk to the people who wind the part, wherever you are.

06

Any order size

One prototype or a full production run, same materials and same workmanship either way. Small quantities don't bother us.
