Digitally controlled IF VGA with low noise figure of less than 3.0 dB

Integrated Device Technology has announced a digitally-controlled IF VGA for receiver systems located in cellular base stations and other wireless infrastructure equipment.

The IDT F1200 digitally-controlled IF VGA offers a low noise figure of less than 3.0 dB and a broad 23 dB control range with 7-bit resolution, resulting in better QoS for cellular base stations. This device offers 200 ohm differential input and output impedances enabling seamless integration into the RF signal path.

"Our new IF VGA provides the high SNR and low distortion that the next generation of wireless receivers require, strengthening IDT's position to satisfy the growing demands of the 4G market," said Fred Zust, general manager and vice president of the Communications Division at IDT. "IDT's pervasive timing and RapidIO interconnect solutions give us excellent visibility and system knowledge to solve the common problems that face our customers. With our system-level approach to solving problems, expansion into the RF signal path was the next logical step. The IDT F1200 is the first in a series of RF signal path products that IDT plans to offer, providing our customers the edge they need to advance their products."
