摘要
采用混合微波集成电路(Hybrid Microwave Integrated Circuit,HMIC)形式设计了一款X波段雷达收发组件。该收发组件分为频综器、功放及内定标源和接收链路三个模块,各模块间通过外接同轴电缆实现信号的互联。充分利用数控衰减器的功能,通过调节放大链路的衰减量,从而达到调节发射输出功率的目的。实物测试表明:在10.5 GHz~12 GHz频率范围内,该收发组件发射输出信号功率10 W、5 W、2 W、1 W四档可调,杂散抑制≥65 dBc,接收通道增益为27.5 dB,噪声系数≤4.8 dB。该组件具有输出信号功率可调、噪声系数小、杂散抑制大等特点,满足项目指标要求。
A X-band radar transceiver module is designed in the form of hybrid microwave integrated circuit(HMIC).The transceiver component is divided into three modules:frequency synthesizer,power amplifier and internal calibration source,and receiving link.The signal interconnection between each module is achieved through external coaxial cables.By fully utilizing the function of digital attenuator and adjusting attenuation of the amplification link,the goal of adjusting the transmission output power is achieved.Physical testing shows that within the frequency range of 10.5~12 GHz,the transmitting and output signal power of the transceiver module is adjustable in four levels:10 W,5 W,2 W,and 1 W,with spur suppression≥65 dBc,receiving channel gain of 27.5 dB,and noise coefficient≤4.8 dB.This component has the characteristics of adjustable output signal power,low noise figure,and high spurious suppression,which meets the requirements of project indicators.
