Abstract
The design of a high-performance and fast switching radar frequency synthesizer was presented. The synthesizer was implemented in a large scale digital phase lock loop chip, with high quality crystal oscillator and digital quick frequency catch circuit. Designed by optimizing technique, this small size synthesizer shows the performances of high work frequency (>10GHz), wide bandwidth (>1000 MHz), fast switching (<10μs), low phase noise ((1kHz)≤ - 90dB/Hz), and low spurious level (<70dB), power output (>65mW), and satisfies the requirements for the new type of radar.
