Re: Using a M57762 ?
You can leave the 12V DC on permanently (with a fuse, of course, but it's very unlikely that it will ever blow).
There are ideas for T/R bias switching in the circuit diagram and
manual for my 30-60W PA board (http://g4ddk.com/Products.html).
This board was designed for 50-432MHz and apart from the lowpass
filter it should also work on 1.3GHz.
