Pasternack Launches New Class AB High Power Amplifiers with Optional Heatsinks

Models Support Popular Octave Bands ranging from 20 MHz to 18 GHz with Psat levels up to 200W

Pasternack has launched a new series of high power, Class AB broadband amplifier modules that incorporate GaN, LDMOS or VDMOS semiconductor technology. The combination of high linearity and efficiency with low distortion them ideal for applications including communications systems, military radio, radar, signal jamming, test and measurement and base stations. 


Pasternack offers a selection of 18 new high power, class AB amplifiers that cover frequency bands from 20 MHz to 18 GHz, feature saturated output power levels ranging from 10 Watts to 200 Watts, and power gain up to 53 dB. Designs operate in a 50 Ohm environment and are unconditionally stable. The compact coaxial packages use SMA or N-Type connectors and have integrated D-Sub control connectors for DC bias, enabled with TTL logic control, current sense and temperature sense functions. These rugged assemblies operate over a wide temperature range from -20°C to +60°C and can withstand relative humidity exposure up to 95% maximum. To ensure optimum baseplate temperature for reliable performance, Pasternack offers 2 new heatsink modules with DC controlled cooling fans that are designed for these power amplifiers.

Pasternack’s new class AB, high power amplifiers and heatsinks are in-stock and available for immediate shipping with no minimum order quantity required.
