10 GHZ DRO OSCILLATOR - ANALOG ATV TRANSMITTER.
This is a DRO OSCILLATOR in 10 GHZ range.
But it can be used like an ANALOG ATV transmitter using an external DRO VIDEO MODULATOR, becouse the DRO in this model work at + 5-6 Vcc, so in the WEB there many schematics of video modulator, one of the best is the PE1RKI modulator.
Output power around 10/13 dBm.
I have the following piece with differents frequency range, so tell me wich frequency you need:
1 piece 10.150 - 10.374 Mhz
