Abstract :
The design, implementation and testing of an MMIC 24 GHz synthesizer for radar distance sensor applications is presented. An oscillator is integrated on one chip together with a buffer amplifier, a power splitter and a receiver mixer. The chip is fabricated in GaAs mHEMT technology and has an area of 3.8 times 2 mm. The VCO is a varactor-tuned push-push oscillator with a tuning range of 1.4 GHz at 24 GHz. The measured output power at the transmitter output of the chip is 10 dBm and the measured phase noise is -98 dBc/Hz at 1 MHz offset frequency. The chip also provides half the LO frequency to a PLL circuit
