Abstract :
A double balanced mixer IC, a 90° phase shifter lC and a carrier switch IC for high speed QPSK modems have been developed using monolithic lumped constant circuit techniques and advanced Si-bipolar process technology. These ICs are applicable to QPSK modems transmitting baseband signals in excess of 400 Mb/s at 1 GHz local frequency.
