UMS has added to its portfolio for space applications with a 5 W GaN medium power amplifier in a surface-mount, hermetic package.

Designed for X-Band radar and Ku-Band satellite downlink communications, the packaged CHA6710-FAB covers 8 to 12.75 GHz, delivers 5 W saturated output power with 35 percent power-added efficiency and has 22.5 dB linear gain.

The MMIC is fabricated with UMS’ “space evaluated” 0.25 µm GaN HEMT process.

The GaN PA is also available as a bare die, part number CHA6710-99F.
