High Power Amplifier System

Model number SSPA 1.1-1.7-30 is a high power RF amplifier module that operates from 1100 to 1700 MHz minimum and is packaged in a rugged enclosure. This power amplifier is employed in radar systems and is also used to transmit high PAR waveforms. This transmit assembly is designed and manufactured for operation in harsh environments where radar and communication systems are deployed. Typical output power is 30W across the band at P3dB. Small signal gain is 46.8 dB minimum. Nominal input power is 0 dBm, but any input power range can be amplified as this module offers a very large dynamic range. Input and output VSWR is 2.0:1 maximum. This unit is equipped with DC and RF switching circuitry that enables and disables the RF devices in 20 uSecs maximum. Typical module efficiency is ~40%. Standard features include reverse polarity protection, output short and open circuit protection, and over/under voltage protection. Temperature and current are monitored and reported by this module. This amplifier operates from a +28 Vdc power supply and operates from -40 to +85ºC base plate temperature. Noise figure is 10.0 dB typically across the band. A high power isolator is employed in the output path of this module.
