Good day!

In some of the articles that I'm reading, I keep seeing references to
a DC injector use in RF ports

They are often referred to as Bias Tee's and are usually found under that
name in manufacturers catalogs.


OFF TRACK:
Funny ... I'm 64 and I have heard about bias tee's numerous times but did
not know what they were. I just called them power adders. In fact, years
ago I made one for a microwave transverter somebody gave me.

Now, I kid you not, I was reading a tech manual *today* and it included a
diagram/purpose of a bias tee.

What are the odds of getting the same tech fact twice in the same day from
two independent sources after 50 years of playing with 'trons?
