IDT Expands Wireless Infrastructure Portfolio by Unveiling First RF Signal Path Solution Product

- New IF VGA with the industry's lowest noise performance,
QoS improvement for multi-protocol 2G/3G/4G wireless base stations

IDT ( www.idt.com , Country Manager for Korea: Sang-Yup Lee), an analog-digital company leading the core mixed-signal semiconductor solutions market, today introduced a Digital Control Intermediate Frequency (IF) Variable Gain Amplifier (VGA) with outstanding SNR performance that improves the Quality of Service (QoS) of receiver systems used in various wireless infrastructure equipment, including cellular base stations. This new device expands IDT's product lineup targeting base station equipment in the ever-growing 4G wireless infrastructure market. This product lineup includes high-performance timing and RapidIO® solutions, as well as various devices from IDT's diverse communications portfolio.

The IDT F1200 digitally controlled IF VGA features very low noise levels of less than 3.0 dB and a wide control range of 23 dB that can be controlled with 7-bit resolution, which can improve the QoS of cellular base stations. In addition, because it has extremely low distortion and a wide spurious-free dynamic range (SFDR), it can be usefully utilized in numerous applications. It offers excellent gain accuracy, allowing for easy digital compensation, and features 200Ω differential input and output impedances, enabling seamless integration into RF signal paths to minimize design effort and risk.

Fred Zust, Vice President and General Manager of IDT’s Communications Business Unit, stated, “The new IF VGA features the high SNR and low distortion performance required for next-generation wireless receivers, meeting the growing demands of the 4G market.
