Product Feature

Product Description
The RTC6703 is a wide-band FM transmitter intended for the application on900 MHz ISM band FM transmission. This chip includes a 900MHz band RF modulator, two channels of audio modulator and internal power amplifier with +15dBm power output referred to external matching network. The 900MHz band RF modulator block, which is frequency-synthesizer based with an integrated VCO, generates the 900MHz band FM signal modulated with video signal and two modulated audio subcarriers at 6MHz and 6.5MHz respectively. Both Stereo and Mono application are available on the chip.
Transmission frequency can be set by internal register via SPI programming. FCC regulations is easy to pass by using RTC6703 with application circuit and single room shielding case.
