Variable Gain Amplifiers (VGA)

IDT offers digitally-controlled intermediate frequency (IF) variable gain amplifiers (VGA) with FlatNoise™ technology, an innovative technology where noise does not degrade as gain is reduced. IDT’s low-noise devices improve quality-of-service (QoS) and ease the signal-to-noise ratio (SNR) requirements of the downstream data converter to reduce system cost. IDT’s IF VGAs are ideal for receiver systems located in cellular base stations and other wireless infrastructure equipment.

Industry’s Lowest-Noise Figure

The IDTF1200 (single), IDTF1240 (dual) and IDTF1241 (dual) low-noise digital IF VGAs are ideal for commercial radio systems with very high SNR requirements. Their extremely low distortions makes the devices very flexible, while the 200 ohm differential input and output impedances allow them to integrate seamlessly into the signal path.

Here are some of the key features and benefits offered by the IDTF1200 family of parts: 

  • Low noise
  • Improved SNR
  • Low distortion
 
  • Improved SFDR
  • High accuracy
  • Easy to compensate
