Millimeter Wave Wireless Link for On-board Chip to Chip Communication

Abstract

In this work, a 120 GHz wireless link for on-board chip-to-chip communication is presented for the case of a 20 mm transmission distance. A Y-shaped antenna is used for wideband, on-board connection, and a PA-antenna-LNA link is measured to evaluate the performance of the channel. The proposed link shows a 3.2 dB peak gain and a 14 GHz, 4 dB gain bandwidth. The 50 Gbps data transmission simulation in the 16-QAM modulation format is carried out. Although the nonideal characteristics of the wireless link cause interference among symbols, the interference can be suppressed by the use of a linear equalizer. Further work on the transmission between transmitter and receiver will be performed.
