摘  要:
针对当前用于农机的无线通讯集成放大器功耗大,受环境影响大的特点,提出了一种工作在中频79Hz的单端全集成Si/SiGe HBT放大器。该放大器由三级共射—共基结构组成,使用了线性可调技术和高性能DC滤波网络。放大器显示在79Hz时最高测量增益为17.2dB,而在整个测量频率范围内有超过40dB的良好反向隔离。在不同温度下测量得到的放大器性能显示其增益在常温和60℃之间,芯片在2.7V工作电压下的功耗仅为52 mW。

摘  要:
For wireless communications integrated amplifier have the disadvantage of large power consumption and vulnerable to environmental impact,this paper proposes a kind of work in the intermediate frequency 79Hz single side of the fully integrated Si/SiGe HBT amplifier.The amplifier consists of three common emitter-common base structures.We used a linear adjustable technology and high-performance DC filtering network.Amplifier display maximum measured gain of 17.2dB at 79Hz,and if the entire measurement frequency range is greater than 40dB,it will have good reverse isolation.Amplifier display the gain between room temperature and 60℃,the chip power consumption is only 52mW at 2.7V operating voltage measured at different temperatures.
