Development of a 340-GHz Sub-Harmonic Image Rejection Mixer Using Planar Schottky Diodes

: We report on the design, fabrication and test of an integrated 320-360 GHz Sub-Harmonic Image Rejection Mixer (SHIRM) using planar Schottky diodes. The integrated circuit uses two separate anti-parallel pairs of diodes mounted onto a single quartz-based circuit. Measurement results give SSB receiver noise temperatures of 3300 K at 340 GHz, with an image rejection from 7.6 dB to 23 dB over the...

Development of An Improved Sub-harmonic Mixer Based on Planar Schottky Diodes at 94 Ghz

Accompany with the rapid development of millimeter-wave science and technology, subharmonically pumped mixers has received more and more attention. In this study, a balanced sub-harmonic fixtuned mixer is designed based on combination of linear/nonlinear circuit simulation. It is realized based on rogers substrate process to minimize the cost and simplify the assembly. The mixer works in the 91...

First results of a 1.2 THz MMIC sub-harmonic mixer based GaAs Schottky diodes for planetary atmospheric remote sensing

We present here the first measurement results of a 1200 GHz heterodyne receiver front-end prototype based on this Schottky GaAs membrane technology. The 1200 GHz subharmonic mixer design, previously reported, uses a suspended MMIC GaAs membrane that feature a balanced pair of planar Schottky diodes and an on-chip MIM capacitor for DC forward biasing capabilities. The possibility to bias the sub...

Broadband Fixed-Tuned Subharmonic Receivers to 640 GHz

This paper will describe the design and testing of solid-state subharmonically-pumped mixers from 380 GHz to 640 GHz. The main goal has been to develop robust, compact, solid-state room-temperature receivers with state-of-the-art sensitivity and broad IF bandwidths for applications such as airborne and space-based microwave sounding. Testing of a 380 GHz integrated mixer has yielded state-of-th...
