Product Description
The RTC6701 is a FM/FSK transmitter intended for application on 2.4GHz ISM band analog FM or digital FSK transmission. The chip includes a RF modulator, two channels of audio modulator and a power amplifier with up to +11.5dBm power output. The RF modulator block, which is frequency-synthesizer based with an integrated 2.4GHz VCO, generates the 2.4GHz FM signal modulated from stereo audio L(left)/R(left) signals. On-chip two audio modulators with stereo audio input signals provide the FM audio modulated signal at 6 MHz and 6.5MHz, respectively. Monaural application is also possible by turning off one of two audio modulators.
Transmission frequency can be set by internal register via SPI programming, or by selecting among 4 fixed channels using three dedicated pins. Output power of +1.5dBm or +11.5dBm can be configured via pins 28 and 29 to fit CE/FCC requirement easily. The device is available in a 32-pin QFN package.
