Minature 600:600 ohm audio coupling transformer
Here are some nice small Integrity Technology brand (***)-010-0014 600 Ohm audio coupling transformers which would work in a variety of audio applications. These are new units which can be built into microphones, reciever outputs, you name it.
I have used similar devices for many things, from handheld telco wireline test sets to audio coupling devices so that I could record SW and BB signals into my computers audio input without the computers noisy RF signals destroying what I was trying to recieve! In particular also, I have used these very transformers for wireline audio amps and meters, and also in 2 way radio base station and voting receiver applications with good results.
These are small sized units, being about 14mm square and 15mm high. The coils in this unit have a DC resistance of 102 Ohms and 134 Ohms respectively. Although I can't find the exact data for this it seems similar (besides mounting ) to the one found HERE.
