Model number SSPA 0.020-1.000-350 is a high power, multi-decade bandwidth, GaN solid state power amplifier. It is packaged in an enclosure that is optimized for airborne or ground applications that require survival in high performance shock and vibration environments. Nominal linear output power is 100 to 200W, but power levels at saturation of 300 to 400W are typical from 100 to 900 MHz. Depending on the application, output power can be backed off to achieve excellent EVM metrics. This unit can be employed in high performance systems where high power, excellent efficiency, and high linearity are required across a large frequency spectrum. Typical power gain is 53 to 57 dB. A nominal 0 dBm input drive is required to achieve saturated output power. The composite power added efficiency with a CW input is between 40 to 50% at room temperature from 50 to 1000 MHz. Input and output VSWR is 2.0:1 maximum. This SSPA can be blanked on and off in 10uSec maximum. Standard features include reverse polarity protection, output short and open circuit protection, and over/under voltage protection. In band harmonics are -17 dBc typical. Noise figure is 10 dB maximum. This power amplifier module operates from -40 to +75ºC base plate temperature. The thermal management system calls for this assembly to be mounted to a heat sink for conduction cooling.
