摘要
介绍了五通道接收机的设计思路以及工作原理,并对其接收系统中的相位一致性和频率合成器做了重点介绍,频率合成器采用ADF4106和AD9858芯片实现。最后对接收机噪声系数和接收增益进行分析设计。通过集成化芯片的使用,实现接收机体积小、功耗低、集成度高的特点。
The implementation scheme and operation principle of the reconnaissance and positioning receiver are introduced, with emphasis on the consistency of phase and the frequency synthesizer. The frequency synthesizer was implemented by AD9858 and ADF4106 chips. Finally, the noise figure and gain of the receiver were given. The designed receiver has the characteristics of low power consumption, small size and high integration.
