IRVINE, CA. Pasternack has just 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 suitable 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 high-power, class AB amplifiers 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 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.
“The addition of these new high-power amplifiers offers our customers more choices to address applications requiring a small-formfactor, high-power RF amplifier that utilizes leading edge semiconductor technology, with the benefit of high linearity and efficiency, and wide dynamic range over a broad frequency range,” said Tim Galla, product line manager at Pasternack.
Pasternack’s new class AB, high-power amplifiers and heatsinks are in-stock and available for immediate shipping with no minimum order quantity required.
