The QPI series of mm-Wave waveguide amplifiers from QuinStar Technology operate from 18 to 110 GHz. The amplifiers deliver an output power of up to 30 dBm with a gain of 50 dB. They require a supply voltage of 9 to 12 V and consumes less than 14 A of current. The amplifiers are available in a module with either a coaxial connector or WR-42 (K-band) and WR-28 (Ka-band) waveguide ports. A combination of these interfaces is also available.
