Im trying to design an FM transmitter to operate at a higher frequency than that of fm radio range. I found some circuits on wireless mic. Is it possible to tune these circuits to about 900 Mhz without compensating the audio quality? Are there IC's able to transmit within this range?
 

Professional Wireless Microphone Systems use uncrowded UHF Band (692 - 722 MHz) and it is probably pssible to re-tune them to 900MHz band.
"Domestic" wireless microphones in most cases operate somewhere around 170MHz and this is just to low to "modify" them for 900MHz ..
 

do you think i should use a wireless telephone's circuit to transmit to that range? are capacitors and inductors practical within that range?
