Power Amplifier Boosts 2 To 4 GHz

Model SSPA 2.0-4.0-100 is a high-power amplifier from Aethercomm built for use from 2 to 4 GHz especially in harsh environments. Based on gallium-nitride (GaN) device technology, the amplifier provides 100 W output power at 3-dB compression with 54 dB small-signal gain. It exhibits maximum input and output VSWR of 2.0:1. The amplifier is equipped with DC switching circuitry that enables and disables the microwave transistors within the amplifier with typical turn-on time of 540 ns and typical turn-off time of 230 ns. Standard features include reverse polarity protection, output-short and open-circuit protection, and over/under voltage protection. The amplifier, which measures 9.25 x 12.00 x 1.50 in., operates from a +28-VDC supply.
