IDT Announces Industry's First FlatNoise™ Dual IF VGA for Multi-mode 4G Base Station Transceivers

IDT's FlatNoise Technology Provides a Virtually Flat Noise Figure as Gain is Reduced, Improving QoSEasing Data Converter SNR Requirements to Reduce System Cost

SAN JOSE, Calif.--(BUSINESS WIRE)-- Integrated Device Technology, Inc. (®) (NASDAQ: IDTI), the AnalogDigital Company™ delivering essential mixed-signal semiconductor solutions, today announced the industry's first FlatNoise dual intermediate frequency (IF) variable gain amplifier (VGA) for multi-mode 2G/3G/4G wireless base station transceivers. IDT's devices offer the industry's best noise figure (4 dB) for maximum gain virtually no degradation when gain is reduced, improving quality-of-service (QoS)easing the signal-to-noise ratio (SNR) requirements of the downstream data converter to reduce system cost.

are dual-channel digitally-controlled IF VGAs featuring IDT's FlatNoise technology. This new technology virtually eliminates noise figure degradation for the critical top 13 dB section of a wide 31 dB gain control range - a stark contrast to other IF VGAs which typically exhibit a dB for dB degradation in noise figure as gain is reduced. FlatNoise eases the SNR requirements of the system's data converter, enabling customers to improve signal qualityuse a more cost-effective, lower-resolution data converter. For many applications, this allows the customer to downgrade from a 14-bit data converter to a 12-bit data converter with comparable system SNR.

"Our new FlatNoise RF products bring tremendous value to the applicationcomplement IDT's leading timingRapidIO® solutions for base station designs," said , vice presidentgeneral manager of the Communications Division at IDT. "The F1240 and F1241 feature the industry's best noise figure and lowest power consumption,join our previously announced as the industry's first products to offer FlatNoise technology. By improving the signal quality at the VGA, we essentially make it easier for downstream devices to operate. This gives system designers flexibility to use a more cost-effective data converter; for example, using a 12-bit device instead of a 14-bit device."

IDT's new IF VGAs feature extremely low distortion (OIP3 = +49 dBm), allowing for higher front-end gain, improving the receiver's sensitivityresulting in additional QoS enhancement. The devices operate over a 10 MHz to 500 MHz frequency range with a typical maximum gain of 20 dBoffer the industry's lowest power consumption (80 mA per channel). In addition, the IF VGAs are extremely accurate, with a gain step error of only 0.04 dB, improving the system SNR performance even further. A parallel or serial communication interface provides control of a 6-bit (0.5dB: F1240) or 5-bit (1.0 dB: F1241) resolution, giving designers maximum flexibility.
