50W GaN power amplifier features 47dBm Psat
Pasternack announces their PE15A5025 50W GaN coaxial power amplifier operating in the popular 2 to 6GHz frequency band. 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.
Applications for the PE15A5025 amplifier include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare.
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.
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 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 (see PE15A5990) is recommended for this model.
“Pasternack’s new PE15A5025 GaN power amplifier operates in the popular 2 to 6GHz frequency band and offers leading edge performance for power and efficiency in a compact package that makes it an excellent choice for demanding applications, explains Tim Galla, Active RF Components Product Manager, Pasternack.
