Integrated demodulator for broadband communication
October 27, 2010 // Phil Ling
Analog Devices has introduced an integrated demodulator for broadband applications, such as cellular base stations, satellite communications, point-to-point (PtP) radios and defence systems. The ADRF6850 demodulator expands ADI's RF/microwave product portfolio and offers the highest level of integration and functionality.
It combines five devices and three RF functions into one small-footprint, surface-mount chip, integrating a 60dB 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 8mm x 8mm LFCSP package.
The ADRF6850 operates over a broad frequency range from 100MHz to 1000MHz and supports narrow band and wideband signal modes up to 250MHz. The device is said to offer best-in-class RF performance with an input IP3 (third order intercept) of 22.5dBm, P1dB (input compression point) of 12dB and a noise figure of 11dB.
Furthermore, 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.
