摘要

介绍了一种低压宽带前置功率放大器的设计。前置功率放大器的作用是将外部功率放大器和内部混频器分开，为功率放大器提供所需的输入功率。放大器采用0.35 /spl mu/m SiGe工艺设计。采用差分拓扑结构是为了减小键合电感的影响。放大器的最大输出功率和最大产量进行了优化。仿真结果表明，该放大器的输出功率为2 dBm，增益为13 dB。带内增益变化小于0.5 dB。经表征后，输出功率始终大于0 dBm。

Pre-power amplifier for 5.2-5.8 GHz band

The design of a low-voltage and broadband pre-power amplifier is presented. The purpose of the pre-power amplifier is to separate the external power amplifier and internal mixer to deliver the required input power to the power amplifier. The amplifier is designed in 0.35 /spl mu/m SiGe technology. Differential topology is used in order to reduce the effect of the bonding inductances. The amplifier is optimized for maximum output power and maximum yield. The simulation results of the amplifier show 2 dBm output power with 13 dB gain. The gain variation is less than 0.5 dB in-band. The output power is always more than 0 dBm after characterization.
