QPI Series Millimeter-Wave Full Waveguide Band Power Amplifiers

Product Description

QuinStar Technology’s series QPI power amplifiers provide state-of-the-art high power performance in the 18-26.5 GHz, 26.5-40-GHz and 75-110 GHz frequency ranges. For K and Ka bands the standard amplifier products are offered with either a coaxial connector or WR-42 (K-band) and WR-28 (Ka-band) waveguide ports (on W-band only WR-10 waveguide is offered).

On the K and Ka bands any combination of these interfaces is available as an option. For all bands integral waveguide isolators are also available for improved input and output matches.
