Abstract :
A 650 GHz imaging receiver with an on-chip folded-dipole antenna in a SiGe technology is presented. The subharmonic 162.5 GHz L0 is supplied by an integrated 6 dBm L0 driver amplifier. The receiver chip occupies 1.2×0.6 mm2 and provides a bandwidth of 635 to 665 GHz, a -13 dBi conversion gain and a 42 dB NF.
