GaN Power Amp Offers High Gain For Military Radio & Comm. Systems


Pasternack announced a new 50 Watt gallium nitride (GaN) coaxial power amplifier operating in the popular 2 to 6 GHz frequency band. The amplifier claims to acheive excellent technical specs with the use of advanced GaN devices. Applications for the PE15A5025 include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare.

“The compact and rugged design delivers high levels of output power and efficiency and has the advantage of high output load impedance that makes port matching easier over wider bandwidths using lower loss components”, Pasternack said.

Key specifications of the new GaN power amplifier include a small signal gain of 50 dB, a Psat or 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. The amplifier requires a +28 Vdc power supply and is unconditionally stable, as mentioned in the Press release.


Other desired 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 amplifier uses 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.

Temperature range is specified from -40°C to +85°C. A compact rugged package withstands harsh military standard environmental test conditions that include humidity, altitude, shock and vibration. An external heatsink with fan for cooling (see PE15A5990) is recommended for this model.
