Analog Devices Adds New Highly Integrated Demodulator for Broadband Communication Designs to Its RF/Microwave
- ADI’s ADRF6850 demodulator saves board space, reduces cost, and shortens design time with
integration and performance in a small package.
NORWOOD, Mass.--(BUSINESS WIRE)-- 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
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
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,
Availability, Pricing and Complementary Products
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
RF IC Portfolio Covers Entire RF Signal Chain
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.
