一种小体积X波段频率合成器设计

介绍了一种小体积频率合成器的设计,该频率合成器通过直接数字频率合成器（DDS）产生线性调频信号,通过锁相环产生固定二本振信号,通过锁相环（PLL）与2 倍频器产生一本振信号,通过变频部分完成二次混频产生射频激励信号。同时采用现场可编程门阵列（FPGA）完成DDS 控制以及与系统通讯,电源控制部分产生各种电源。

Small-Volume X-band Frequency Synthesizer Design

The design of a small volume frequency synthesizer that generates linear frequency modulation signal throughDirect Digital Synthesizer (DDS) is introduced, fixed second local oscillator signal through the Phase-Locking Loop (PLL) andgenerates a local oscillator signal through the phase-locked loop and frequency doubler is produced. At the same time,Field-Programmable Gate Array (FPGA) is used to complete DDS control and communication with the system, and the powercontrol part generates various power sources.
