Norwood, MA (10/26/2010) - Analog Devices, Inc. (ADI), a world-leader in high-performance semiconductors for signal processing applications and RF ICs (radio frequency integrated circuits), today introduced a new 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 expands ADI’s RF/microwave product portfolio and offers the highest level of integration and functionality by combining five devices and three RF functions into one small-footprint, surface-mount chip.
Unlike discrete implementations that use a multi-chip approach, ADI’s single-chip ADRF6850 demodulator saves considerable board space, reduces cost, and simplifies development by integrating 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. A complete data sheet and samples are available at www.analog.com/adrf6850.
The ADRF6850 operates over a broad frequency range from 100 MHz to 1000 MHz and supports narrow band and wideband signal modes up to 250MHz. The device offers best-in-class RF performance with an input IP3 (third order intercept) of 22.5 dBm, P1dB (input compression point) of 12 dB and a noise figure of 11 dB. Furthermore, the ADRF6850 also supports the user selected SPI/I2C serial interface and is fully supported by the latest version of ADI’s popular PLL design tool, ADIsimPLL.
The ADRF6850 is in production now and is available for $7.50 per unit in 1,000-unit quantities. It is the companion device to ADI’s recently released ADRF6750 modulator.
Using a unique combination of design skills, system understanding and process technologies, Analog Devices offers the broadest portfolio of RF ICs covering the entire RF signal chain from industry-leading high-performance discrete RF function blocks to highly-integrated multi-functional single-chip RF solutions. ADI’s RF portfolio includes TruPwr™ RMS power detectors and logarithmic amplifiers; PLL and DDS synthesizers; RF prescalers; VGAs; ADC drivers, gain blocks, LNAs and other RF amplifiers; RF mixers; direct conversion modulator and demodulator products; integrated transceivers, transmitters and receivers and more. These products are supported by a wide range of free design tools, evaluation boards and other design resources to ease the development of RF systems.
