Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all

I would like to design a MICROSTRIP
DIRECTIONAL COUPLER of 20dB for UHF band. I am quite new in this kind
of couplers. How to begin the design with ADS and its MOMENTUM tool?Which
are the steps?

I am also new to
this topic. From what I remember, in ADS there are models of coupled
lines and also of couplers under the Microstrip line library, which
you can utilize as a start point for your design.
First, a linear
simulation to estimate the dimensions of the microstrip lines based
on the required coupling, reflections and isolation requirements.
The next step is to do EM simulations.
In addition, I have
found in Google this article, which shed some light on the design steps:
