Integrated Device Technology (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’s noise figure is less than 3.0dB and a broad 23dB 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.
