50 Watt GaN Coaxial Power Amplifier Targets Commercial & Military Applications

Pasternack has announced a new 50 Watt gallium nitride (GaN) coaxial power amplifier that operates in the popular 2 to 6 GHz frequency band. The PE15A5025 has a compact and rugged design that delivers high levels of output power and efficiency and has the advantage of a high output load impedance that makes port matching easier over wider bandwidths using lower loss components. Applications for this amplifier include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare.

This amplifier offers 50 dB of small signal gain with a saturated output power level of 47 dBm typical and 30% power added efficiency (PAE). While generating 50 watts of saturated output power under worst case conditions, the output harmonic response is -15 dBc and spurious levels are kept at -70 dBc. This amplifier requires a 28 Vdc power supply and is unconditionally stable. Other features include integrated voltage regulation, bias sequencing circuitry, DC control TTL logic, DC current monitoring, and over temperature shutdown at +90°C baseplate temperature for added reliability.

The PE15A5025 has female SMA input/output RF connectors and a 15 Pin Micro-D Female socket is used for DC, TTL blanking, and over current and temperature monitoring. This assembly operates over a temperature range from -40°C and +85°C and the rugged package is designed to withstand harsh military standard environmental test conditions that include humidity, altitude, shock and vibration. An external heatsink with fan for cooling is recommended for this model.
