“…This paper reports on a high-gain InP double heterojunction bipolar transistor (DHBT) SHM for -band applications. The SHM topology consists of an LO frequency doubler, RF preamplifier, and single-ended mixer, as previously proposed for pHEMT-based SHMs [5]. The use of an LO frequency doubler in front of a mixing stage in order to obtain the wanted subharmonic mixing functionality has also recently been demonstrated in 0.18-m CMOS technology [6].…”

A novel 180 hybrid with two sections of three-conductor coupled-line structure inhered different operating frequencies with overlapped characteristic and perfect isolation between the -port and -port is employed to implement a Ka-to M-band single-balanced subharmonic mixer (SHM) in a 0.15-m GaAs pHEMT process with a compact die size of less than 0.82 0.83 mm . The thorough analysis based on the scattering matrix of the 180 hybrid is also presented. Incorporating the inherent features of the 180 hybrid with an antiparallel diode pair configuration, the proposed SHM achieved a wide operating bandwidth from 37 to 85 GHz with low conversion loss from 9 to 14 dB, enhanced local oscillation (LO)-to-RF isolation and 2LO-to-RF isolation under 10-dBm LO power level. This proposed architecture is really attractive to SHM design in modern millimeter-wave territory.
