Hi...

...this is possible but ,,, but not as easy....

There's a small sawtooth generator for the vco frequency inside... that
match the desired frequency to the pll circuit. If you unterstand
to programm this microcontroller there's no problem to controll this
sawtooth generator and activate the amplifier stages.

STILL ANYONE DOING THIS ???

the idee is that in ericsson phones you can find a murata vco operating at 946 Mhz. you can use that device
