Pasternack launches Class AB high-power amplifiers up to 200W for bands from 20MHz to 18GHz

Pasternack Inc of Irvine, CA, USA (an Infinite Electronics brand that makes both passive and active RF, microwave and millimeter-wave products) has launched a series of high-power Class AB broadband amplifier modules that incorporate gallium nitride (GaN), LDMOS or VDMOS semiconductor technology. The combination of high linearity and efficiency with low distortion over a wide dynamic range makes them suitable for applications including communications systems, military radio, radar, signal jamming, test & measurement and base stations, says the firm.

The 18 new high-power class AB amplifiers span frequency bands from 20MHz to 18GHz, and feature saturated output power levels ranging from 10W to 200W and power gain up to 53dB. Designs operate in a 50Ohm 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.

The 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 insure 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-form-factor, 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,” says product line manager Tim Galla.
