We report a 2-channel 140GHz transmitter using low-cost antenna and packaging technologies. The arrays use 8-element series-fed linear microstrip patch antenna arrays fabricated on an Isola Astra MT77 printed circuit board (PCB). Two such antennas, connected to a CMOS multi-channel transmitter IC with 2dBm output power form the two-channel transmitter. At 145GHz, the measured transmitter EIRP is 14-15dBm in single-channel operation and 19-20dBm in two-channel operation. QPSK transmission experiments over 25 cm distance show open eye patterns at 10.0 Gb/s rates.
