340 GHz Integrated Receiver in 250 nm InP DHBT Technology
Artikel i vetenskaplig tidskrift, 2012
A 340 GHz integrated receiver based on a 250 nm InP DHBT technology is presented in this paper. It consists of a 2X2 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.
