Pasternack has expanded its range of gallium nitride (GaN) coaxial power amplifiers to include amplifiers that operate from 30 MHz to 7.5 GHz, with gains of 43 to 60 dB, saturated power levels from 10 watts to 100 watts with 20 to 35% Power Added Efficiency (PAE).
GaN has emerged as the technology of choice in power amplifier designs. The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies. These rugged connectorized designs have the advantage of high output load impedance that offers easier impedance matching over wider bandwidths using lower loss components. Applications include commercial and military radar, jamming systems, medical imaging, communications and electronic warfare.
All of the high power GaN amplifiers from Pasternack have single voltage supplies which are internally regulated. The 50 ohm input/output matched designs are adaptable to a range of power and modulation requirements. These PAs also show impressive harmonic response (-15 to -20 dBc) under the worst case conditions. These amplifiers are designed to withstand environmental conditions such as humidity, altitude, shock and vibration. Some models are also equipped with integrated heat sinks and cooling fans. Most designs are EAR99. Pasternack's GaN power amplifiers are in-stock and ready to ship now.
