100兆赫至1000兆赫综合宽带接收机 100 MHz to 1000 MHz Integrated Broadband Receiver
Product Details
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 narrowband 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.
