In this paper, a 420GHz GaAs monolithic integrated sub-harmonic mixer based on planar Schottky diode is presented. We combine the diode 3D model, nonlinear model and passive circuit by field-circuit method, then optimize the circuit through harmonic balanced method, finally study the GaAs monolithic integrated 420GHz sub-harmonic mixer. Simulated results for the mixer achieved DSB conversion loss...
In this paper, a 420GHz Sub-Harmonic Mixer based on planar schottky diode is presented. The mixer circuit was fabricated on the 50um thick quartz substrate with a pair of anti-parallel flip-chipped schottky diodes. The planar schottky diode is fabricated in China Electronics Technology Group Corporation-13(CETC-13). Simulated results for the 420 GHz mixer achieved DSB conversion loss of 6.2dB@404GHz...
This paper describes the design, simulation and measurement of a Schottky sub-harmonic mixer working around 370GHz. The device is based on an anti-parallel pair of planar Schottky diodes flip-chip mounted onto a single quartz-based microstrip circuit. The best DSB noise temperature of about 3500K is measured with LO at 184.5GHz. The performance of the mixer at room temperature and the liquid nitrogen...
This paper presents the design and simulation of a novel fixed-tuned 310-350-GHz wide-band sub-harmonic mixer. The mixer is based on an anti-parallel pair of GaAs Schottky diodes fabricated at European company. The circuits are fully integrated with the RF/IF filter and flip-chipped onto a suspended quartz-based substrate. A best double-sideband-mixer loss of 5.7 dB was achieved with 5 mW of LO power...
