摘要

本文比较了分别用ADF5355和HMC833芯片实现的两种宽带锁相环频率合成器的性能。研究了它们作为0中频接收机的本振，工作频率为1ghz ~ 6ghz。为了提供低于-40 dBc所需的谐波电平，最终解决方案基于ADF5355，然后是四个低通滤波器的开关组。相位噪声水平优于-90 dBc @ 1 kHz，杂散低于-70 dBc。

Low phase noise synthesizer optimized for wideband 0-IF radio receiver

In this paper the performance of two wideband PLL frequency synthesizers realized with ADF5355 and HMC833 chips respectively has been compared. Both of them were investigated as a local oscillator for 0IF receiver operating from 1 GHz to 6 GHz. In order to provide required harmonics level below -40 dBc the final solution is based on the ADF5355 followed by a switched bank of four low pass filters. The phase noise level is better than -90 dBc @ 1 kHz and spurious are lower than -70 dBc.
