适用于DBF的多通道中频宽带数字接收机设计

Design of a multi-channel wideband digital IF receiver for DBF system

介绍了一种适用于DBF的8通道中频宽带数字接收机的设计方案。首先介绍了主要芯片的设计选择和设计原理,并就DBF多通道中频宽带数字接收机的关键指标进行了试验测试,给出测试数据。结果证明了该方案很好地解决了多通道接收机的幅相一致性和稳定性问题。

A design scheme of an 8-channel wideband digital IF receiver for the DBF system is in- troduced. Firstly, the design selection and principle of the main chip are presented, and then a test is made on the key indexes of the multi-channel wideband digital IF receiver with the test data giv- en. The results show that the scheme can preferably solve the problem of anaplitude-phase consisten- cy and stability of the multi-channel receiver.
