Modification to G3WDG010 2.3GHz transverter to increase power output - DRAFT

The G3WDG010 2.3GHz transverter has a nominal power output of about 1mW. This can be increased by several dB to the point where the transverter should be able to drive the 1W PA directly by the addition of an extra MAR6.

The extra components are shown in the photograph and consist of 4 x veropins, 1 x MAR6, 1 x 100pF, 1 x 10nF, 1 x 330R and a coil with the same dimensions as used on the neighbouring modamp.

To fit the extra parts, cut the track to allow the modamp to be fitted with a sharp scalpel blade, lifting the copper off with the scalpel or a soldering iron. Drill two holes either side of the track 1mm dia and fit veropins with the heads on the track side. Solder the veropins to the groundplane on the other side of the board. Make another cut in the track near the output connector, to allow the extra 100pF chip to be fitted.

Drill two more holes for veropins for the decoupling and power feed components. One of these is grounded, the other has the groundplane relieved for the +12V feed (connected to the +12V on transmit line).

If means of measuring power output are available, try adding some tuning tabs to see if more output can be obtained.

If it is desired to incorporate the SMTLO into the box, please refer to the 1296 Transverter for details on how to do this.
