Re: Simple low power gain device

Hi John,
If you go this route i have some real BFG591s if you need one ( which work at 13cms also)

Wouldn't it be easier to reduce the drive sensitivity of the transverter?

But failing that, a bipolar amp like the right hand side of the diagram shown here 
(I know it says adjust\ble to +25dBm, but that's off an 8V rail.   The device can give a watt out )

'Morning all

I have a G4DDK Anglian transverter which produces +20dBm on 144MHz (works

At the masthead I have a DB6NT 13cms transverter which requires approx.
+23dBm for full output.

Taking into account feeder losses and a bit of headroom for comfort I'm
looking for a simple linear amplifier to boost my 144MHz drive from +20dBm
to +26dBm.

Any of the Mitsubishi RA series modules would be capable, but a significant
overkill ! Any other suggestions please ?
