本文讨论了一种优化变压器负载射频电路的设计方法，并给出了最大可用输出功率的简化公式。优化过程基于一种新的综合变压器的性能指标，该指标用于量化其作为调谐负载运行时的性能。利用所提出的方法，在40-GHz-f/sub - T/ SiGe HBT技术中实现了用于5 ghz无线局域网应用的高度线性上转换器。该电路实现了输出1-dB压缩点为4.5 dBm，功率增益为18 dB，而从3-V电源仅汲取34 mA。
In this paper a design methodology for the optimization of transformer-loaded RF circuits is discussed and a simplified equation for the maximum available output power is presented. The optimization procedure is based on a novel figure of merit for the integrated transformer, which was introduced to quantify its performance when operated as a tuned load. By means of the proposed approach, a highly linear up-converter for 5-GHz wireless LAN applications was implemented in a 40-GHz-f/sub T/ SiGe HBT technology. The circuit achieves an output 1-dB compression point of 4.5 dBm and a power gain of 18 dB, while drawing only 34 mA from a 3-V power supply.
