Abstract
This work presents a mmW frequency selector as the core of the LO generator for E-band transceivers. Two 10 GHz apart mmW LO frequencies generated by a mixer from a single 50 GHz frequency and its 5 GHz submultiple are sent to the proposed circuit that outputs a single frequency tone of either 45 GHz or 55 GHz. The circuit is realized in BiCMOS 55nm technology combining 55nm CMOS transistors and SiGe HBTs with fT and fmax ~300 GHz. The circuit is based on injection-locked oscillators, presents a phase noise @ 1MHz offset of -110 dBc/Hz with 0 dB of excess phase noise added to the input, and consumes 53mW.
