Abstract :
This paper describes a W-band, fixed tuned receiver that achieves double side-band noise figure less than 5.5 dB over 10 GHz bandwidth for both LO and RF ports. This low DSB noise figure includes a 1.6 dB contribution from an amplifier with 1000 MHz bandwidth. Only three milliwatts of LO power, obtained through a broadband frequency doubler, are required for receiver´s optimum performance without biasing the mixer diodes.
