ADI's Integrated Modulator Reduces Component Count w/Industry-Leading
April 22, 2009 -- NORWOOD, Mass.
RF Performance for Broadband Satellite Applications
--(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
modulator offers the highest level of
integration and functionality by combining four devices into one small footprint.
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
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
Operating within the 950 MHz to 1575 MHz frequency range and on a single 5-volt power supply, the
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
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
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:
