Description

The ADRF6850 is a highly integrated broadband quadrature demodulator, frequency synthesizer, and variable gain amplifier (VGA). The device covers an operating frequency range from 100 MHz to 1000 MHz for use in both narrow-band and wideband communications applications, performing quadrature demodulation from IF directly to baseband frequencies.The ADRF6850 demodulator includes a high modulus fractional-N frequency synthesizer with integrated VCO, providing better than 1 Hz frequency resolution, and a 60 dB gain control range provided by a front-end VGA.Control of all the on-chip registers is through a user-selected SPI interface or I2C interface. The device operates from a single power supply ranging from 3.15 V to 3.45 V.APPLICATIONS Broadband communications Cellular communications Satellite communications
