A Compact Hybrid G-band Heterodyne Receiver Integrated with Millimeter Microwave Integrated Circuits and Schottky Diode-Based Circuits

This paper presents a compact hybrid G-band (170–260 GHz) heterodyne receiver module incorporating both Millimeter Microwave Integrated Circuits (MMICs) and Schottky diode-based circuit. An on-chip sextupler Low Noise Amplifier (LNA), along with Sub-Harmonic Mixer (SHM), are integrated into the demonstrated singular module, which is carefully designed arranged co-simulations in electromagnetic thermal domain. Through this methodology, terahertz fabricated volume of only 27 × 20 mm3. The measured results indicate that double-sideband conversion gain 10.5–17.5 dB from 195 GHz to 230 GHz, while noise temperature 1009–1158 K. As result, provides recorded miniaturized hardware applicable for Integration Sensing Communication (ISAC) systems.
