摘要

本文提出了一种基于自动相关监视广播(ADS-B)的T/R前端。带有ASK/BPSK调制器的发射器前端和接收器安装在两个不同的金属盒中。前端实验结果验证，在与1090MHz载波偏移10KHz时，锁相环模块相位噪声低于-90dBc/Hz，发射机输出脉冲功率峰值大于51dBm。测量到的接收机噪声系数小于2.5dB。锁相环模块、调制器和功率放大器模块的总功耗约为4.35W。

A L-band transceiver front-end for ADS-B system

In this paper, a T/R front-end based on Automatic Dependent Surveillance Broad-cast (ADS-B) is proposed. The transmitter front-end with ASK/BPSK modulators and the receiver are installed in two different metal boxes. Experimental results of the front-end verify that the phase noise of the PLL module is lower than -90dBc/Hz at 10KHz offset from carrier of 1090MHz, and the peak output pulse power of the transmitter is more than 51dBm. And the noise figure of receiver measured is lower than 2.5dB. The overall power consumption of the PLL module, modulators and the power amplifier module is about 4.35W.
