摘要:

Ka波段一体化收发信机是无线通信系统中的重要电路,它对整个系统的噪声系数,灵敏度等关键指标起决定性作用。文中对Ka波段一体化收发信机的工作原理进行了阐述,同时给出了整机功能实现框图,分析了接收通道单元、本振单元、发射通道单元和电源控制单元共4个单元的设计方案,并给出了仿真结果与测试结果。试验结果表明,Ka波段一体化收发信机接收机噪声系数≤2.2 dB、增益≥60 dB、输入输出驻波、相位噪声杂散、镜像抑制等指标均满足技术要求。发射机1 dB压缩点功率≥30 dBm,增益≥50 dB,三阶交调,杂波抑制等均满足实用技术要求,并根据测试结果对Ka波段一体化收发信机的部分技术指标提出了进一步优化的方案。

Abstract:

The integration of the Ka-band transceiver has significant effect on the system noise factor,sensitivity,and other key indicators of the wireless communication system circuit.The working principles of the integrated Ka-band transceiver with the overall block diagram given.A detailed analysis is made of design of the receiver channel unit,the local oscillator unit,emission channel unit,and power control unit and both simulation results and test results are provided.The results show that with a noise factor ≤ 2.2 dB,gain ≥ 60 dB,the input and output standing wave,the phase noise spurious image rejection and other indicators of the integrated Ka-band transceiver all meet the technical requirements;with the transmitter 1 dB compression point power ≥ 30 dBm and gain ≥ 50 dB,the TOI,clutter suppression also satisfy the technical requirements.And in accordance with the test results,part of the technical indicators of the integrated Ka-band transceiver are optimized and improved.

Key words: The integrated transceiver;receiver;transmitter
