Product Description

The RTC6705 is a wide-band FM transmitter intended for the application on 5.8GHz bands FM

transmission. This chip includes a 5.8GHz band RF modulator, two channels of audio modulator

and internal power amplifier with +13dBm power output referred to external matching network.

The 5.8GHz band RF modulator block, which is frequency-synthesizer based with an integrated

VCO, generates the 5.8GHz 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, or by selecting six

dedicated pins. Two stages output power of +2dBm or +13dBm can be configured via pins 34

and 35. Both CE and FCC regulations are easy to pass by using RTC6705 with application

circuit and single room shielding case.
