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.
