Abstract

In this paper, with the combination of DDS, PLL, multiplier and mixing techniques, a millimeter wave (mm-wave) full-coherent frequency synthesizer with low phase-noise and spurs is developed. It includes a mm-wave source. A linear frequency modulation (LFM) generator and a microwave source serving as the second local oscillator for the receiver. An external 100 MHz temperature-controlled crystal oscillator is used as the coherent clock for all the sources. The phase noise and spurs of the mm-wave signal have been analyzed and estimated. Measured results show that the output frequency is 34.855~34.865 GHz, the stepping frequency is 100 KHz, the output power is larger than 16 dBm, and the phase noise level is about -92 dBc/Hz at an offset of 10 KHz.
