Abstract:
This paper presents an active W-band up-converting double-balanced Gilbert mixer realized in 800 nm transferred substrate (TS) InP-DHBT technology. It consists of an active balun and a frequency doubler followed by a double-balanced Gilbert cell mixer. The local oscillator (LO) of the mixer operates from 39 to 45 GHz with an input power of less than 3 dBm. The mixer achieves a single sideband (SSB) conversion gain of 8 dB ± 2 dB in the frequency range 75 ... 96 GHz. The measured output 1 dB compression (OP1dB) reaches -7 dBm and -8.5 dBm at 75 GHz and 86 GHz, respectively. The up-converter offers more than 15 GHz IF bandwidth, at a DC consumption of only 80 mW.
