A planar wideband millimeter-wave subharmonic receiver

A wideband planar subharmonic mixer has been designed for millimeter-wave operation. The receiver consists of a back-to-back Schottky-diode pair integrated at the base of a wideband log-periodic antenna. The antenna is backed by a hyperhemispherical lens and was tested at 178.5 GHz with a 90-GHz loc...

Summary:A wideband planar subharmonic mixer has been designed for millimeter-wave operation. The receiver consists of a back-to-back Schottky-diode pair integrated at the base of a wideband log-periodic antenna. The antenna is backed by a hyperhemispherical lens and was tested at 178.5 GHz with a 90-GHz local oscillator. The results indicate a single-sideband conversion loss of -12.8 dB without any RF or IF matching networks. The subharmonic monolithic approach results in an inexpensive wideband receiver, and the design can be easily extended to receiver arrays.< >
