Project .. Transverter 1296 MHz - 144 MHz

 

 

Transverter 1296/8 - 144 MHz: the construction requires a lot of attention starting from the soldering of the GasFets: all precautions must be taken to avoid electrostatic charges. The PTT can be controlled externally or with the internal Vox (Br3 jumper inserted). Max applicable input power 2 Watt. Max output power 700 mW. As you can see in the photo, it is necessary to shield the central microstrips with a scrap of sheet metal. These are just some general recommendations, upon request I can provide the original article.

 

1296 MHz amplifier: with an input signal of 100/200 mW we have 3 Watts at the output. The implementation does not pose particular problems, only the ends must be dissipated with a sheet of metal to be applied to the underlying part, folding the sides appropriately so as not to force on the BFQ34..

 
Oscillators for UHF /SHF converters: as can be seen in the table shown in the electrical diagram, it is possible to obtain output signals from 1404 MHz to 2808 MHz: in the photos the last stage is missing and we have 1278 / 1296 MHz output with quartz from 106.5 MHz and 108 MHz respectivel .
