摘要： 设计了一种应用于无线侦收系统的小型化超宽带接收组件，在有限的体积内集成了两路变频接收通道、两个本振源及一个校准源。采用毫米波高本振的超外差二次变频架构，降低了组合干扰抑制的难度。基于一系列多功能芯片进行电路的小型化设计，腔体正面微波电路和反面控制电路通过通孔进行互联，有效减小了组件厚度和横向尺寸。利用内部校准源产生信号，通过ADC采集DLVA电压进而调节数控衰减器的方式，可优化双通道增益及一致性等指标，基本可以做到免调试，提高了批生产效率。

Design and implementation of a 0.8~18 GHz ultra-wideband receiver module

Abstract： A miniaturized ultra-wideband receiver module is designed for electronic reconnaissance system in this paper. The receiver module contains two down-converter receiving channels, two LO synthesizers and a self-checking circuit in limited area. The module is of superheterodyne with twice frequency conversion by millimeter wave local oscillator，and the miniaturized circuits based on a series of multi-function MMICs are designed. To reduce the thickness and lateral dimensions，the through holes between microwave circuits and control circuits are adopted for interconnection. To realize self-calibration function，self-calibration synthesizer generates a signal，and then the ADC collects the voltage of DLVA，finally the gain and the consistence of two receiving channel are optimized based on adjusting the digital attenuators. Through above steps, the receiver module is easily manufactured, thus batch production efficiency is improved.
