Optimal Design for Matching Network of L-band Low Noise Amplifier

摘要

This paper introduces a matching network composed of lumped elements and transmission lines, which is more accurate and compact compared to the traditional one. Meanwhile, the added microstrip lines is used for bonding pads and connection lines on printed circuit board (PCB), and the dimensions of these microstrip lines can be adjusted to compensate for the errors brought by the real elements without changing any values of placed inductors or capacitors. This method makes the design of low noise amplifier (LNA) matching networks more easy and convenient.
