Abstract :
This paper reports a QPSK modulator (MOD) and demodulator (DEMOD) in InGaP/GaAs HBT process and its measured performance. When connected back-to-back in a packaged form it was demonstrated to have throughput of greater than 2 Gb/s at 30 GHz. This is the first time these results have been reported.
