Abstract :
This paper presents the design and performance of a broadband, low power, +3.0 V pHEMT Gilbert cell downconverter IC for satellite communication systems. The downconverter is fully integrated on to a single die and requires no external matching elements. The MMIC demonstrates 300-8000 MHz RF-LO bandwidth and 185-2085 MHz IF bandwidth.
