摘要
研制了一款利用系统级封装技术(SIP)的小体积X频段双通道收发变频模块,在其内部集成了采用不同工艺制成的器件。模块把发射通道和接收通道集成到一个腔体中,并实现收发分时控制。模块采用上下双腔结构,不同腔体之间采用BGA球栅阵列进行垂直连接,显著减小模块体积,模块体积为21 mm×16 mm×3.8 mm。模块主要指标测试结果为:接收通道输入P-1dB≤-10 dBm,接收信号增益30~35 dB,接收通道隔离度大于等于55 dB,接收噪声系数小于等于8 dB;发射通道增益10~12 dB,发射通道最大输出功率大于等于12 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,模块可在-55~+85℃正常工作。实测结果与仿真结果基本一致。
A miniaturized X-band dual-channel radio frequency(RF)transceiver module is designed by using system in package(Sip)technology,which integrates devices based on a variety of process.Receiving channel and transmitting channel are inte-grated into a cavity,and time-sharing control for transmitting and receiving is achieved.Double-cavity structure is used and dif-ferent cavities are vertically interconnected through the ball grid arrays to reduce the module size significantly.The size of SIP module is 21 mm×16 mm×3.8 mm.The main measured technical specifications of the modules are as follows:The P_(-1),dB of re-ceiving channel≤-10 dBm,receiving signal gain 30~35 dB,isolation degree of the receiving channel≥55 dB,receiving noise figure≤8 dB;gain of transmission channel 10~12 dB,maximum output power of transmission channel≥12 dBm,second and third harmonic suppression≥60 dBc,clutter rejection≥55 dBc,the module can function properly within the temperature range of-55~+85 C.The measured results are basically agreed with the simulation results.
