Single Chip Ka-Band Transceiver
1991
This paper presents the first monolithic single chip FM-CW radar transceiver operating at 40 GHz. The chip is the largest multifunction MMC demonstrated operating at millimeter-wave frequencies. The design implements transmitter receiver, and duplexer functions using a single process InGaAs HEMT technology. The transmitter operates in the frequency range from 37 to 40 GHz and has greater than 12.0 dl3m output power. The receiver converts the signals in the same frequency range to an IF’ frequency of 10 to 100 MHz with 0 dB conversion loss. When integrated with an antenna, the chip is a fully functional FM-CW radar which detects the doppler frequency shift from reflected objects. The paper will describe the design, fabrication, and performance of the chip.
