Microstrip Double-Stub Load Matching

The following matches a 50 Ohm line to a 100 Ohm load at 10 GHz using a double-stub component. This was designed using the ADS passive circuit DesignGuide tool. This method is a great alternative to using the Smith Chart matching tool for lumped elements if you need a microstrip line for matching.

Substrate:

dsmat2

 

Momentum simulation result (can be tuned to center better at 10 GHz):
