Pasternack has introduced a 50W gallium nitride (GaN) coaxial power amplifier operating in the 2GHz to 6GHz frequency band. The PE15A5025 features a compact and rugged design, and promises 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.

PE15A5025

This GaN power amplifier from Pasternack offers 50dB of small signal gain with a saturated output power level of 47dBm typical and 30% power added efficiency (PAE). While generating 50W of saturated output power under worst case conditions, the output harmonic response is -15dBc and spurious levels are kept at -70dBc. The amplifier requires a 28VDC power supply and is unconditionally stable. 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, detailed the company.

The PE15A5025 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. The assembly operates over the temperature range of -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.

Applications for the PE15A5025 amplifier include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare.
