Featuring broadband frequencies ranging from 0.5MHz to 20GHz, Fairview Microwave has released a complete portfolio of coaxial high reliability power amplifiers that can operate over an extreme temperature range from -55 to +85°C. These amplifiers are suited for demanding environments with applications including electronic warfare, instrumentation, military comms, radar, point-to-point radio, telecomms, test & measurement, medical and SATCOM.

The power amplifiers are designed to overcome the electrical and mechanical stresses that are seen with exposure to harsh environments. These RF amplifiers boast rugged package enclosures that can withstand vibration and shock exposure during handling and transport. Several models in this offering are designed to meet MIL-STD-202 and MIL-STD-810 environmental test conditions, while some amplifier designs are environmentally screened in production to MIL-STD-202 test conditions. Some models feature integrated heatsink and cooling fans for improved thermal dissipation performance resulting in extended operating life. For added reliability against harsh environments, certain models utilise hermetically sealed coaxial packages.

Fairview’s high reliability power amplifiers can generate saturated output power levels up to 100W and all models require only a single positive voltage supply ranging from +12 to +42VDC. Small signal gain levels range from 11 to 58dB with IP3 linearity up to +66dBm resulting in high dynamic range. All models are unconditionally stable.

Brian McCutcheon, Vice President and General Manager, Fairview Microwave, commented: "Our new high-rel power amplifiers are designed to meet a number of military standards which result in highly reliable operation and give designers added confidence and assurance for long term optimum performance."

The RF amplifiers are in-stock and available now.
