Abstract :
A direct conversion demodulator at 60GHz based on Gilbert cells down-converter is presented in this paper. The OOK modulation allows using a single detector on receiver side to discriminate the 0 or 1 data. The conventional diode based detector presents conversion losses and obviously a high noise figure. Derived from the classic Gilbert cell mixer the demodulator presents a conversion gain of 9.7dB, a Noise Figure of 10dB for an input signal as low as -28dBm. This high sensitivity allows applications as chip to chip communications with high data rate. A data rate of 10Gbps has been measured without significant degradation with an efficiency of 2.1pJ/bit.
