Abstract: In this paper, according to the needs of airborn ultra-short wave receiver, the system-level design and simulation of RF front-end circuit is carried out by using Advanced Design System(ADS). By analyzing the performance requirements of ultra-short wave receiver, combined with the main working principle and technical indicators of the receiver, the structure of the dual-conversion superheterodyne receiver is selected as the implementation scheme. The system level simulation model of RF front-end of receiver is established in ADS. The key indicators of RF front-end of the design such as noise figure, sensitivity, gain and intermodulation distortion are designed, analyzed and simulated by ADS. The simulation results show that the RF front-end meets the requirements of the design.

引言

機(jī)載超短波接收機(jī)在軍事通信系統(tǒng)及民用通信系統(tǒng)都有著廣泛應(yīng)用,近年來隨著高性能集成芯片的不斷發(fā)展,,機(jī)載超短波接收機(jī)朝著寬帶,、高靈敏度、高線性度以及高度集成化的方向發(fā)展,。射頻前端處于整個(gè)接收機(jī)最前端,,對(duì)整個(gè)接收機(jī)的性能起著至關(guān)重要的作用[1],因此對(duì)超短波接收機(jī)射頻前端的性能需求也在不斷提升,。ADS(Advanced Design System)軟件是美國Agilent公司研發(fā)的通信系統(tǒng)仿真軟件,,可用于射頻電路級(jí)和系統(tǒng)級(jí)的仿真設(shè)計(jì)。本文根據(jù)某型號(hào)超短波接收機(jī)技術(shù)指標(biāo)要求對(duì)射頻前端進(jìn)行系統(tǒng)級(jí)設(shè)計(jì),并利用ADS對(duì)射頻前端進(jìn)行系統(tǒng)級(jí)建模與仿真,。
