Analog Devices introduces a demodulator for broadband applications

Analog Devices, Inc. (ADI) has made available a highly integrated demodulator for broadband applications, such as cellular base stations, satellite communications, point-to-point (PtP) radios and defense systems. ADI's new ADRF6850 demodulator adds on to ADI's RF/microwave product portfolio and combines five devices and three RF functions into one small-footprint, surface-mount chip.

ADI's single-chip ADRF6850 demodulator combines a 60 dB VGA (variable gain amplifier), a fractional-N PLL (phase locked loop) synthesizer with VCO (voltage controlled oscillator) and two baseband ADC drivers all in an 8 mm x 8 mm LFCSP package.

The ADRF6850 operates over a frequency range from 100 MHz to 1000 MHz and supports narrow band and wideband signal modes up to 250MHz. The device offers input IP3 (third order intercept) of 22.5 dBm, P1dB (input compression point) of 12 dB and a noise figure of 11 dB. The ADRF6850 also supports the user selected SPI/I2C serial interface and is fully supported by the latest version of ADI's PLL design tool, ADIsimPLL.
