PROJECT TITLE :
340 GHz Integrated Receiver in 250 nm InP DHBT Technology
A 340 GHz integrated receiver based on a 250 nm InP DHBT technology is presented in this paper. It consists of a 2$times$2 differential patch array antenna, a sub-harmonically pumped Gilbert mixer and an IF buffer amplifier. Performance of the integrated receiver is evaluated by setting up a RF link in the frequency band of 302–338 GHz. At 338 GHz RF and 170 GHz LO, the peak conversion gain of 11.8 and 14.0 dB is achieved with and without antenna, respectively. A double-sideband noise figure of 17 dB at room temperature is obtained from direct noise figure measurement .
