LCGT shall be planned to be the first-generation detector with an advanced technique for employing a cryogenic mirror in order to firstly detect a gravitational wave, and after detection, the detector will serve as an astronomical tool to observe the Universe through gravitational wave radiation. In collaborative observation with the LIGO, GEO and Virgo projects, LCGT desires to contribute to t...

This article presents an innovative architecture for the implementation of electrostatic discharge (ESD) protection millimeter-wave (mm-wave) devices. The proposed is based on use 3-dB couplers, whose coupled outputs have been shorted to ground node. In order reduce physical dimensions coupler and reach high coupling required this application, Coupled Slow wave CoPlanar Waveguides (CS-CPWs) was...

This paper deals with a feasibility study for a System-onChip (SoC) mm-wave radiometer devoted to space-based observation of solar flares and operating in the Ka-band. The radiometer has been designed in 250 nm SiGe BiCMOS process. The circuit integrates a three stages differential LNA with 37.2 dB gain and 4.8 dB noise figure at 36.8 GHz and a differential square-law detector based on HBTs, fe...
