Description
Gidday All,
I have recently had some success modifying some old Cell gear to run on 1296 MHz.
The result is a few High Gain, 20 Watt PA's, fully Linear.
An Input of 0 dBm typically gives about 4 Watts and +10 dBm (10 Milliwatts) gives around 20 Watts Output (PSAT).
The devices (Brick Amp & GaAs FET) on this PCB operate on +24 Volts with a max current draw of about 3 Amps.
The new Owner will need to mount this modified PCB on their own Heatsink.
The I/O lines can easily be swapped out to suit the new owner.
Rather annoyingly, the Substrate of the O/P Transistor sits below the PCB so I've included a small sheet of Aluminium to fit as a "shim" Plate between the PCB & the Heatsink.
The PIX shows a Roll of Solder for scaling...
Selling $45 each.
Cheers,
Alan - VK3XPD.
