Abstract
This paper presents a chip set aiming at high resolu-
tion imaging systems for real-time people screening applications
operating near the W-band. The frequency of operation ranges
from 70 GHz to 82 GHz for optimal image resolution and depth of
focus. The frequency generation for both receiver and transmitter
chips consists of a mixer based frequency quadrupler with an input
amplifier requiring
20 dBm of input power. The receiver RFIC
contains 4 channels including LO generation and distribution. T
