【摘要】：针对近年来快速发展的多模卫星组合导航技术需求,提出覆盖主流全球卫星导航系统(GNSS)频段(包括GPS、GLONASS、伽利略、北斗)的低噪声放大器模块.该低噪声放大器模块采用SIP封装技术,在一个3 mm×3mm×1mm的塑料封装内集成了低噪声放大器芯片及输入输出匹配电路等片外电路,封装外无需额外分立元件.低噪声放大器芯片采用低噪声的0.25μm GaAs pHEMT工艺流片.在芯片设计中,提出新型的有源偏置电路,可以抵御电源电压和环境温度的波动,使该低噪声放大器模块能够在复杂的环境中稳定工作.测试结果表明,该低噪声放大器模块在工作频段内噪声系数约为0.65dB,增益可达20dB,输入输出回波损耗小于-10dB,中心频率输入三阶互调阻断点为0.6dBm,电源电压为3.3V,功耗为15mW.
[Abstract]:In view of the rapid development of multi-mode satellite integrated navigation technology in recent years, a low-noise amplifier module covering the GNSS band (including GPS GLONASS, Galileo, Beidou) of the mainstream global satellite navigation system (GNSS) is proposed.The low noise amplifier (LNA) module adopts SIP encapsulation technology. The LNA chip and the input / output matching circuit are integrated in a 3 mm 脳 3mm 脳 1mm plastic package. There is no need for additional discrete components outside the package.The low noise amplifier chip adopts low noise 0. 25 渭 m GaAs pHEMT process.In the chip design, a new type of active bias circuit is proposed, which can resist the fluctuation of power supply voltage and ambient temperature, so that the low noise amplifier module can work stably in complex environment.The test results show that the noise coefficient of the LNA module is about 0.65 dB, the gain can reach 20 dB, the input and output echo loss is less than -10 dB, the center frequency input third order Intermodulation blocking point is 0.6 dBm, the power supply voltage is 3.3 V, and the power consumption is 15 MW.
