Phil,

The Motorola TLE1713A Power Amplifier is rated at 75 watts continuous duty
for 450-470 MHz.  It is a component of the MICOR C64RCB station.  All of the
technical data is in Service Manual 6881025E50.  The bad news is that the
manual is NLA from Motorola, but the good news is that it has been scanned
in full-page format as a PDF document, and will soon be available for
download at the RBTIP.

You should use this PA with the appropriate power control module, so that
the power can be controlled and the PA protected against poor SWR.

Subject: [Repeater-Builder] TLE1713A-1 at 448 MHz

  

I do apologize if this has been answered already (I did spend about 20
minutes going through old messages). I just received a very clean TLE1713A-1
amp, and I am intending to use it around 448 MHz for a ham repeater. Of
course, I have no documentation on this unit. Applying 13 VDC to the control
line, I got a little over 150W out into a 50 ohm dummy load at 448 MHz, and
about 80W out at 462 MHz. My question is, do I simply need to regulate the
control line voltage to get the output power down where it belongs, or is
there some circuit tuning that I should do as well? If the latter, I am in
need of a procedure or at least some schematics or service manual. Any help
would be greatly appreciated! Thanks for your time.
