Model SSPA 0.1-0.8-70 from Aethercomm is a gallium-nitride (GaN) power amplifier with 80 W typical output power at 3-dB compression from 100 to 800 MHz. Designed for harsh environments, it offers typical gain of 57 to 58 dB with power-added efficiency of 45 to 60 percent across the operating band under saturated conditions. The maximum input and output VSWR is 2.0:1. The amplifier includes DC switching circuitry that enables and disables the RF devices inside the amplifier in typically 4000 ns for turn on and typically 1650 ns typical for turn off time. Standard features include reverse polarity protection, output short and open circuit protection, and over/under voltage protection. The amplifier, which operates from a +28-VDC supply, has a typical noise figure of 5 dB. It is housed in a module measuring 2.5 x 6.4 x 1.0 in. with SMA female connectors.
