Experimental Evaluation of Differential Chip-to-Antenna Bondwire Interconnects above 110 GHz

Abstract : Bondwire interconnects for differential chip-to-antenna interfaces are investigated. Two different compensation structures for different interconnect lengths are designed and evaluated using dedicated transmit and receive BiCMOS modules operating across a 110 to 156 GHz band. Measurement results demonstrate that a 9 GHz bandwidth and a minimum insertion loss of 0.2 dB can be achieved for interconnects as long as 0.8 mm, showing that the well established wire-bonding techniques are still an attractive solution even beyond 100 GHz. Reproducibility of the proposed solution is assessed as well.
