Abstract: This letter introduces a silicon–germanium (SiGe)-based subharmonic mixer (SHM) optimized for THz radar applications, operating at a center frequency of${360}$GHz with a${3}$-dB bandwidth of${72}$GHz. This mixer is a key component in a fully integrated receiver, featuring a wideband${90}$-GHz voltage-controlled oscillator (VCO), a frequency doubler stage, and power amplifier (PA) stages. The mixer exhibits a conversion gain of${-6.1}$dB while maintaining an excellent input compression point of${>}4$dBm, accompanied by a simulated noise figure (NF) of${24.8}$dB. Moreover, a current consumption of only${8.6}$mA underlines the energy efficiency.
