A 120 GHz Wireless Radio Link for High-speed Chip-to-Chip Communication

A 120 GHz wireless radio link for high-speed chip-to-chip communication is presented. Targeting a signal-to-noise ratio (SNR) of 15 dB and transmission distance of 10 cm, the wideband up and down-conversion mixers, PA, and LNA were designed using wideband matching techniques and gain boosting circuits. The proposed sub-blocks showed wideband characteristics over 25 GHz and met the target gain when measured. Results from measurement of the integrated transmitter and receiver will be presented.
