Reflection Modeling Based Broadband Matching Network Design

摘要

In this paper, a new broadband matching network design approach based on reflection modeling is proposed, which has two parts: impedance data generation and modeling. In the approach, firstly the output impedance data of the matching network is obtained to get the desired flat transducer power gain in the passband. Next the output reflection data are calculated using the obtained impedance data, then they are modeled as a bounded real function. Then this function is synthesized and the desired lossless matching network with initial element values is obtained. A double matching example is solved to illustrate the use of the proposed approach. It is seen that proposed approach provides suitable initials for CAD tools for final trimming.
