Designing and building a line of solid-state power amplifiers based on gallium-nitride GaN) transistors and active devices, Diamond Microwave offers amplifiers at X- and Ku-band frequencies as alternatives for traveling-wave-tube amplifiers (TWTAs) in demanding defense, aerospace, and communications applications. Certified to ISO 9001:2008, the firm believes that its amplifiers provide excellent pulsed-power performance with power-to-volume ratio that is among the highest in the industry. The GaN power amplifiers offer pulsed output-power levels to 150 W and ae flexible in layout and architecture for a wide range of applications. The company displayed a Ku-band amplifier at the recent International Microwave Symposium with peak pulsed output power of 125 W at 16.5 GHz and 1-dB bandwidth of 1.5 GHz.
