This paper describes multi-band low noise amplifiers (LNAs) utilizing input matching transformers. We investigate a conventional dual-band LNA circuit utilizing a transformer, and show our analysis and simulation results for its circuit. Based on this, we propose a triple band LNA with transformers. We have calculated characteristics of the dual-band and triple-band LNAs. As the results, the LNAs show gain of 20dB while maintaining good input matching, in the frequencies at 2.59GHz, 3.50GHz and 5.41 GHz. Then we discuss configuration and design of coupling coefficients of the transformers.
