Abstract :
This paper presents the design of a VCO and a frequency divider integrated together with a phase-frequency detector and a mixer on one transceiver chip for a 24GHz FM-CW radar system. The VCO is a differential varactor-tuned microstrip oscillator with 1.25GHz tuning frequency, which delivers a flat output power of 7dBm at each of the two differential 50Ω loads over the entire frequency range. Additional differential RF-outputs drive the inputs of the receiver circuits, a frequency divider with a division ratio of 32 and a single-balanced-mixer. The transmitter circuit has been fully integrated in the Motorola production 0.35μm SiGe-BiCMOS technology.
