Abstract
A low-power FMCW 80 GHz radar transmitter
front-end chip is presented, which was fabricated in a SiGe bipolar
production technology (
GHz, GHz).
Additionally to the fundamental 80 GHz VCO [1], a 4:1-frequency
divider (up to 100 GHz), a 23 GHz local oscillator (VCO) with a
low phase noise of
dBc Hz (1 MHz offset), a PLL-mixer
and a static frequency divider is in tegrated together with several
output buffers. This chip was designed for low power consumption
(in total
W, i.e., 100 mA at 5 V supply
