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.
The ADRF6850 is a highly integrated broadband quadrature demodulator, frequency synthesizer, and variable gain amplifier (VGA) designed for use in both narrow-band and wide-band communications applications. It covers an operating frequency range from 100 MHz to 1000 MHz and performs quadrature demodulation from IF directly to baseband frequencies.
The device includes a high modulus fractional-N frequency synthesizer with an 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 on-chip registers is achieved through a user-selected SPI or I2C interface.
