A 77GHz monolithic IMPATT transmitter in standard CMOS technology

In this paper, a fully integrated transmitter at 77GHz is presented in a 0.18/spl mu/m standard CMOS technology. The system consists of a lateral IMPATT diode and a microstrip patch antenna. The antenna impedance seen by the IMPATT diode is optimized using the high frequency electromagnetic (EM) field solver, Sonnet, which is matched to the measured impedance of the diode. The transmitted power had an offset frequency of -0.13% from the simulation results.
