IDT expands wireless infrastructure portfolio with first in family of RF signal path solutions

SAN JOSE, USA: Integrated Device Technology Inc. (IDT) announced a digitally-controlled IF VGA with very high SNR for improved Quality of Service (QoS) for receiver systems located in cellular base stations and other wireless infrastructure equipment.

The new device expands IDT’s product offerings for base station equipment in the growing 4G wireless infrastructure market, which today includes high performance timing, RapidIO solutions, and other devices from IDT’s rich communications portfolio.

The IDT F1200 digitally-controlled IF VGA offers a very 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. The extremely low distortion provides increased spurious-free dynamic range (SFDR), making the device flexible for use in myriad applications. In addition, the excellent gain accuracy makes it easy to digitally compensate, while the 200 ohm differential input and output impedances allow it to integrate seamlessly into the RF signal path, minimizing design effort and risk.

“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.”

The IDT F1200 is currently sampling to qualified customers and is available in a 5x5 mm 28-pin QFN package, priced at $4.85 each for volumes of 10,000 units.
