New 50W GaN Power Amplifier

The PE15A5025 50W GaN coaxial power amplifier operates in the popular 2 to 6 GHz band. Its 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 this amplifier include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare. It offers 50 dB of small signal gain with a saturated output power level of +47 dBm typical and 30% PAE. While generating 50W of saturated output power under worst-case conditions, the output harmonic response is -15 dBc and spurious levels are kept at -70 dB. The 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 +90º C baseplate temperature for added reliability.
