Abstract

This paper shows the design of a reduced size system that drives local oscillator (LO) signal generated by a voltage controlled oscillator (VCO) in the transceiver system, which is based on I and Q architecture. The aim of this work is to obtain a small system capable to drive two differential mixers and one phase locked loop block with high power efficiency. The entire system drives two differential outputs to their respective mixers with a minimum differential LO power of -1 dBm and a maximum of 0 dBm between 56.5 and 60 GHz. The system furnishes -7dBm to the PLL, allowing the control of the carrier. The output ports are matched at 50 Ω and they achieve a reflection loss under 10 dB in the whole band of interest. The power consumption of the entire system is 58 mW. The size including RF and DC pads is 0.6×0.7 mm².
