160GHz pulsed transmitter with packaged antenna array in 65nm CMOS

This paper presents a 160GHz center frequency pulsed transmitter for short range radar applications. An array of four transmitters was implemented in a single chip with antennas implemented on the package. Each transmitter can be independently phase shifted, allowing transmit beamforming. The implemented transmitter is capable of producing pulses of 100ps wide (>20GHz RF bandwidth) with 160GHz carrier frequency. The measured effective isotropic radiated power (EIRP) is 14.5dBm for continuous wave operation. The entire chip consumes 1.4W from 1.2/1.4V supplies in a 65nm digital CMOS process.
