This letter presents the design of a wide band 8th harmonic mixer, using an anti-parallel pair of planar Schottky GaAs flipp-chip diodes fabricated onto a suspended quartz-based microstrip circuit. Simulations predict conversion losses are well below 23dB from 330 to 500GHz. The design offers an solution to simplify the local oscillator signal generation and realize the goal of low frequency conversion...
This paper presents the design and simulation investigation of a 850GHz low-loss subharmonical mixer based on GaAs Schottky barrier diodes. Our group analyzed the topology of subharmonic mixer, device modeling of Schottky diodes, the 3D electromagnetic passive circuits and the mixer circuitry with optimum performance. The antiparallel diodes pair is fabricated from China Electronics Technology Group...
In this paper, a terahertz wideband sub-harmonic mixer based on the Schottky anti-parallel diodes pair and MASTER technology is presented. The mixer circuit is fabricated on a 0.05mm quartz substrate including Schottky anti-parallel diodes pair, RF/LO transition, IF matching networks and filtering circuits. The diode circuit is fabricated on a quartz substrate directly by MASTER technology. The research...
