New for November 2021

Here we will present some advice on coupled line cuplers

page under construction, come back soon...

fr the most part we are taling a out cppletrs that ause used to sniff out a sample of a signal, not hubrid 3dB couplers.

 

1. Microstrip couplers stink.  They have no directivity.  this is an outcome of teh fact that even and odd modes have different phase velocities.

 

ditectivity and return loss are interre\ated. If teh best you can do is 20 dB return loss, the best directivity you will get is 20 dB.

 

Loss and coupled amplifude are related
