ADRF6850 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 munications applications, performing quadrature demodulation from IF directly to baseband frequencies. The ADRF6850 demodulator includes a high modulus fractional-N frequency...
