Abstract :
A flexible CPW-MMIC (coplaner-waveguide monolithic microwave integrated circuit) chipset has been fabricated for 120 GHz future broadband wireless systems. The power amplifier has small signal gain of 8.5 dB from 115 to 135 GHz. The 1 dB compression point is 3 dBm at 120 GHz. We employed a traveling wave switch configuration for the ASK modulator. The insertion loss of the switch is less than 1.5 dB and the on-off ratio is more than 13.5 dB at 120 GHz. For the ASK modulator-demodulator chipset, the measured BER is 1e/sup -10/ for 10 Gbit/s PRBS 2/sup 11/-1 data at -13 dBm input power and 120 GHz RF frequency. The frequency doubler has an output power of -11 dBm at 120 GHz with fundamental and harmonics rejection better than 30 dBc.
