IF Variable Gain Amplifier Improves QoS in Multi-Protocol 2G/3G/4G Wireless Base Stations

Wed, 03/23/2011 - 10:05am
SAN JOSE, Calif. -- (BUSINESS WIRE) -- Integrated Device Technology, Inc. (IDT®) today 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.

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.
