Abstract :
A 27-41 GHz monolithic balanced frequency doubler fabricated using the 0.13 μm SiGe BiCMOS technology is presented in this letter. The balanced doubler consists of a balun, a driver amplifier (DA), a common-base (CB) doubling core and a medium power amplifier. The CB topology is used to increase the bandwidth and for the ease of matching with the balun. The proposed frequency doubler attained a measured gain of 16.8-19.8 dB, an output power of 1.3-4.3 dBm, and a fundamental rejection of better than 25.7 dB (from 27 to 41 GHz) at an input power of 15 5 dBm. An maximum output power of 8 dBm with dc power consumption of 35 mW and corresponding power added efficiency (PAE) of 16.9% have also been achieved. The chip size is 0.75 mm × 0.45 mm.
