Pasternack launches 50W GaN coaxial power amplifier operating at 2-6GHz

Pasternack Enterprises Inc of Irvine, CA, USA (which makes both passive and active RF, microwave and millimeter-wave products) has launched the PE15A5025, a 50W gallium nitride (GaN) coaxial power amplifier operating in the 2-6GHz frequency band. 

The compact and rugged design delivers high levels of output power and efficiency and has high output load impedance, making port matching easier over wider bandwidths using lower-loss components. Applications include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare.

The GaN power amplifier offers 50dB of small-signal gain with a saturated output power level (Psat) 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 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 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 -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 heat-sink with a fan for cooling (see PE15A5990) is recommended for this model.
