Abstract :
The design and the measurement results of a direct downconversion mixer for the 60 GHz ISM band are presented. Based on a Gilbert structure, the mixer is optimised for high bandwidth and designed in a 180 GHz SiGe technology. Without any buffer stages, the measured conversion gain is Gconv=-7 dB. The remarkably high IF bandwidth allows downconverting a continuous band of 15=GHz with flatness of ±1.4 dB and enables the design of ultra-high data rate transceivers.
