RTC6715 CMOS 5.8GHz Band FM Receiver
Product Description
The RTC6715 is a highly integrated FM receiver intended for application on 5.8GHz band FM
demodulation. This chip includes a low noise amplifier, mixer, IF amplifier, FM demodulator,
AGC, audio demodulators, audio Amps and noise squelch. With RSSI voltage output, the
instantaneous radio signal strength can be monitoring. RTC6715 is able to demodulate the FM
modulated video and Stereo audio signals sourced from RTC6705 and separate the desired signal
at the dedicated output pins. Both Stereo and Mono application are available on the chip.
RTC6715’s operation frequency can be set by SPI programming, or by selecting six dedicated
pins. Both CE and FCC regulations are easy to pass by using RTC6715 with application circuit
and single room shielding case.
Features
Single 3.3V supply power
5.8GHz band FM demodulator with two audio subcarrier demodulators at 6MHz/6.5MHz
