Original Kurzfassung:
For 77?GHz automotive radar applications, a monolithic frequency
multiplier with a multiplication factor of 18 is presented. The main
circuit of the multiplier chain consists of two frequency tripler and one
doubler. Additionally interstage amplifiers and filters are integrated in
a
200?GHz SiGe:C production technology. The output power is ?1dBm
for a wide input power range (?20dBm to +8 dBm) at room temperature and
76.5 GHz output frequency. The output power flatness is better than 2 dB
for an output frequency range of 69 GHz to 80 GHz. The
power consumption of the multiplier is 170mW at a single supply
voltage of 3.3V.
