About RF Cafe™


Frequency Mixers, Converters, Doublers,
Multipliers, Modulators & Transceivers
Manufacturers & Services

Frequency mixers, converters, multipliers, modulators & transceivers are all lumped together on this page since they all involve some sort of frequency translation, either up or down. Often, the terms can be interchanged. This way no matter what you have come in search of, it should be listed here.

Need help with your application? Try here: Mixer, Converter, Multiplier, Modulator & Transceiver Design Data

My policy is to only list companies that actually manufacture product or offer services related to the page title subject. Product distributors and sales representatives are not listed (they have their own Distributors page). This helps guarantee that each listing offers a unique product or service.

Triad RF Systems
Triad RF SystemsEast Brunswick, New Jersey
855-558-1001 ×1

Triad RF Systems comprises three partners with over 40 years of accumulated knowledge of what is required to design, manufacture, market, sell and service RF/Microwave amplifiers and amplifier systems. We do not make decisions via committee or after time-consuming meetings; instead when an idea is suggested, we typically prototype it and if successful, turn it into product. "We view Triad more as a technology partner than a vendor for our line-of-sight communications product line."

We Currently Offer the Following:

 • Power Amplifiers: Standard, Ultra-linear,
                              Pulsed, Broadband

 • Bi-Directional Amplifiers

 • Rack Systems

 • Tower-Mount Amplifiers

 • Low-Noise Amplifiers

 • Frequency-Translating Amplifiers:
      - Tx-only    - Tx & Rx

 • Custom Amplifier Systems
