Overview

Solid-State Power for Critical Systems

RF Essentials high power amplifiers are designed for applications where output power, gain flatness, and thermal stability are non-negotiable. Every module is built with split-block machined housings, gold-plated waveguide interfaces, and integrated heatsinking for continuous operation under demanding conditions.

Our HPAs cover the standard waveguide bands from WR-42 (18 GHz) through WR-8 (110 GHz), with output power levels ranging from hundreds of milliwatts at the highest frequencies to hundreds of watts at Ka-band and below. GaN technology is used where output power density is paramount; GaAs pHEMT MMICs are selected where gain flatness and noise performance are critical.

FAQ

Frequently Asked Questions

What is the difference between GaN and GaAs power amplifiers?

GaN (Gallium Nitride) amplifiers deliver higher power density and are preferred at Ka-band and below where output power is the primary driver. GaAs (Gallium Arsenide) pHEMT amplifiers offer better gain flatness and lower noise, making them the standard choice at V-band (40-75 GHz) and above. At millimeter wave frequencies beyond 90 GHz, InP (Indium Phosphide) technology is typically required for usable gain and efficiency.

What waveguide bands do RF Essentials high power amplifiers cover?

RF Essentials offers high power amplifier modules across 11 standard waveguide bands: WR-42 (18-26.5 GHz), WR-28 (26.5-40 GHz), WR-22 (33-50 GHz), WR-19 (40-60 GHz), WR-15 (50-75 GHz), WR-12 (60-90 GHz), WR-10 (75-110 GHz), WR-8 (90-140 GHz), WR-6 (110-170 GHz), WR-5 (140-220 GHz), and WR-3 (220-325 GHz). Custom sub-band configurations are available on request.

Can I get a custom frequency range or output power level?

Yes. All RF Essentials high power amplifiers can be configured for custom frequency sub-bands, specific output power targets, modified flange interfaces, and non-standard packaging. Contact our engineering team with your system requirements for a tailored solution.

What thermal management is included in the amplifier modules?

Every RF Essentials HPA module includes integrated heatsinking within the split-block housing. Cold-plate mounting interfaces are standard for system-level integration. For high-duty-cycle or continuous-wave applications, active cooling options including liquid cold plates and forced-air configurations are available.
