3:1 microwave combiner - RF Cafe Forums
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 Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

I want to know about 3:1 directional couper (combiner). Can anyone provide me papers, articles or circuits about it?
Thanks for your time and help.

This is my first post, so please excuse my newbieness.
I'm reading up on LNA design, and I'm curious about the DC bias feedback setup using a reactive component (e.g. inductor) at the NPN's emitter lead to improve stability.
Can someone direct me to the formal analysis of this with regards to relating it to stability? I'm assuming that it helps maintain the collector current to have a uniform stability across a band of frequencies. I'm just not to sure how to come up with the reactive component value.
I can see the results right away using ADS, but I would like to see some sort of analysis on paper.
Thank you very much!
