摘要:
研制了一种小体积的S频段射频收发系统级封装(SIP)模块,内部集成了基于多种工艺的器件。模块接收通道一次变频,发射通道二次变频,内部集成中频和射频本振信号源。模块采用双腔结构,不同腔体之间通过绝缘子进行垂直互连,大大减小了模块体积,模块体积为40 mm×40 mm×10 mm。模块采用正向设计,其主要指标的测试结果为:接收通道动态范围-100~-40 dBm,输出信号0~2 dBm,噪声系数小于等于2.8 dB,带外抑制大于等于50 dBc;发射通道输出信号大于等于2 dBm,二次、三次谐波抑制大于等于60 dBc,杂波抑制大于等于55 dBc,相位噪声在1 kHz和10 kHz处分别小于等于-82 dBc/Hz和-91 dBc/Hz。实测结果与仿真结果基本一致。

Abstract:
A miniaturized S-band radio frequency(RF) transceiver module is designed by using system in package(SIP) technology.The module integrates devices based on a variety of process. Receiving channel is realized by single-conversion,transmitting channel is realized by double-conversion,and the intermediate frequency(IF) and RF local oscillator(LO) signal source is integrated internally. Double-cavity structure is used and different cavities are vertically interconnected through the insulator to reduce the module size largely. The size of module is 40 mm×40 mm×10 mm.Forward design is used and the measured main technical specifications of the module are:receiving channel dynamic range -100~-40 dBm,output signal 0~2 dBm,noise figure≤2.8 dB,out-band rejection≥50 dBc; transmitting channel output signal≥2 dBm,second and third harmonic suppression≥60 dBc,clutter rejection≥55 dBc,phase noise≤-82 dBc/Hz@1 kHz,≤-91 dBc/Hz@10 kHz.The measured results are basically agree with the simulation results.
