Abstract :
A combined frequency doubler and tripler is proposed for wideband millimeter wave frequency generation in CMOS. The circuit consists of a push-push FET frequency doubler along with a single-balanced mixer based frequency tripler. The frequency doubler-tripler can generate frequencies in the range of 23-48 GHz with more than -20dBm output power into 50Ω. The conversion gains of the doubler and tripler are measured to be -2.6dB and -12.3 dB, respectively, with a 0dBm input at 14.4GHz. Fabricated in 0.13-μm CMOS, the circuit has an active area of 600×440 μm2. The frequency multipliers consume 12.6mW dc power from 1.2V supply, while the output buffers consume 11.9mW.
