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 over a wide dynamic range make them ideal for a variety of applications including communications systems, military radio, radar, signal jamming, test and measurement and base stations.
Pasternack offers a comprehensive selection of 18 new models that cover frequency bands from 20 MHz to 18 GHz that feature saturated output power levels ranging from 10 W to 200 W and power gain up to 53 dB. Designs operate in a 50 Ω 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 highly reliable performance, Pasternack offers two new heatsink modules with DC controlled cooling fans that are specifically designed for these power amplifiers.
