Analog Devices Press Release - 4/22/2009

ADI's Integrated Modulator Reduces Component Count w/Industry-Leading
RF Performance for Broadband Satellite Applications

Visit Analog Devices April 22, 2009 -- NORWOOD, Mass.--(EON: Enhanced Online News)-- Adding to its broad portfolio of RF ICs, Analog Devices, Inc. (ADI), a world-leader in high-performance semiconductors for signal processing applications, today introduced a new highly integrated modulator for broadband satellite communications applications, such as VSAT (very small aperture terminals). ADI's new ADRF6750 modulator offers the highest level of integration and functionality by combining four devices into one small footprint.

Previous broadband satellite communication designs required a variety of RF ICs to form an IF (intermediate frequency) signal path. This multi-chip approach took up considerable board space, added system complexity and increased bill-of-materials costs. ADI's ADRF6750 modulator saves space, reduces cost, and lowers complexity by integrating an analog I/Q quadrature modulator, fractional-N PLL (phase locked loop) synthesizer, VCO (voltage controlled oscillator) and digitally controlled RF attenuator, all within an 8 mm — 8 mm LFCSP package. It also supports a user-selectable SPI/I2C serial interface that simplifies design and allows maximum flexibility.

Operating within the 950 MHz to 1575 MHz frequency range and on a single 5-volt power supply, the ADRF6750 modulator enables 10 Hz frequency increments, and the integrated output attenuator provides 47 dB output gain control with 1 dB step resolution. The device also features monitoring-output and output-disable-control capabilities. Furthermore, the ADRF6750 modulator offers best-in-class RF performance, including an output compression (P1dB) of 8.5 dBm, output third order intercept (IP3) of 21 dBm and noise floor of 148 dBc/Hz.

Availability and Pricing

The ADRF6750 modulator is sampling now with volume production scheduled for July 2009. It is available for $5.75 per unit in 1000-unit quantities. For more information, visit: http://www.analog.com/pr/ADRF6750.
