Diamond Microwave reveals ultra-compact GaN SSPA

The broadband gallium nitride amplifier offers up to 100W peak pulsed power and 50W average power
Diamond Microwave is extending its range of GaN-based solid-state power amplifiers (SSPAs) to include a 2 - 6GHz model that can be operated in either pulsed or CW mode.

The DM SC50 01 is an ultra-compact broadband amplifier that complements Diamond Microwave’s existing SSPAs in X-Band and Ku-Band.

All of Diamond Microwave’s amplifiers are suited for use in demanding defence, aerospace and communications applications.

“We are releasing provisional data at IMS 2014 for a new 2 - 6 GHz ultra-compact design, which is demonstrating 100W peak power in pulsed mode at 2GHz and an average power capability of 50W across the full band,” says Richard Lang, managing director at Diamond Microwave.

“This amplifier measures only 120 x 100 x 20mm3 excluding the heat sink. Once again we are pushing the boundaries of solid-state power amplifier technology with an extremely compact solution.”

The amplifier designs are flexible in layout and architecture, and are fully customisable to meet individual specifications for electrical, mechanical and environmental parameters. Amplifiers with pulsed power outputs in excess of 1kW, and with multi-octave performance are also under development.

Diamond Microwave is exhibiting its products at booth #1651 at the IEEE International Microwave Symposium in Tampa, Florida.
