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 et 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
