Industry's first dual IF VGA supports multi-mode 4G base station transceivers
January 26, 2012 // Paul Buckley
Integrated Device Technology is claiming the industry’s first FlatNoise dual intermediate frequency (IF) variable gain amplifier (VGA) for multi-mode 2G/3G/4G wireless base station transceivers. The company’s devices claim to offer the industry’s best noise figure (4 dB) for maximum gain and virtually no degradation when gain is reduced, improving quality-of-service (QoS) and easing the signal-to-noise ratio (SNR) requirements of the downstream data converter to reduce system cost.
The IDT F1240 and F1241 are dual-channel digitally-controlled IF VGAs featuring IDT’s FlatNoise technology. This 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 quality and use 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.
The company's IF VGAs feature extremely low distortion (OIP3 = +49 dBm), allowing for higher front-end gain, improving the receiver’s sensitivity and resulting in additional QoS enhancement. The devices operate over a 10 MHz to 500 MHz frequency range with a typical maximum gain of 20 dB and offer the industry’s lowest power consumption (80 mA per channel). In addition, the IF VGAs are 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 (0.5 dB: F1240) or 5-bit (1.0 dB: F1241) resolution, giving designers maximum flexibility.
The IDT F1240 and F1241 are currently sampling to qualified customers and are available in a 5x5 mm 32-pin QFN package.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
