High Power
Amplifiers
GaN and GaAs MMIC-based solid-state power amplifier modules with waveguide interfaces. Split-block construction, integrated thermal management, and gold-plated housings for maximum output power across mmWave and microwave bands.
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.

View CategoryFrequently Asked Questions
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.
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).
