摘要
采用模拟调频方案,设计了一种小型化线性调频微波收发(T/R)组件。该微波T/R组件在实现所需的调频中心频率和带宽的同时,保证了调频稳定度。T/R组件的调频中心频率为(4 300±15)MHz,调制带宽为(150±1)MHz,调制线性度小于1.2,发射功率大于20dBm,接收噪声系数小于3dB,收发隔离度大于80dB。此T/R组件的尺寸仅为50mm×40mm×12.3mm,在同类型产品中具有较明显优势。
A compact linear frequency modulation microwave T/R module was proposed,which utilized analog frequency modulation scheme.The central frequency of frequency modulation and bandwidth were both realized in this module,while the frequency modulation stability was guaranteed.The T/R module had a central frequency of4 300±15 MHz,a modulation bandwidth of 150±1 MHz,a modulation linearity less than 1.2,a transmission power more than 20 dBm,a receiving noise figure less than 3dB,a receiving-transmitting isolation more than 80 dB.The T/R module occupied an area of 50mm×40mm×12.3mm.It was competitive in the market.
