A 30-180 GHz harmonic mixer-receiver

The authors have combined integrated circuit antenna technology with microwave circuit design and a back-to-back Schottky diode chip to build a wideband millimeter-wave harmonic mixer-receiver. The design is planar, very simple to build, and yields excellent performance from 30-180 GHz. Application areas include wideband early warning systems and search and rescue applications, and for extending the range of spectrum analyzers and power meters to the millimeter-wave region.<>
