Dual IF Digital Variable Gain Amplifier GENERAL DESCRIPTION The IDTF1241 (1 dB steps) is an IF VGA for Diversity Basestation receivers. The device offers significantly better Noise and Distortion performance than currently available devices. It is packaged in a compact 5x5 Thin QFN with 200 ohm differential input and output impedances for ease of integration into the receiver lineup. COMPETITIVE ADVANTAGE The IDTF1241 IF VGA improves system Signal-to-Noise Ratio (SNR), especially at lower gain settings. Via IDT’s proprietary FlatNoiseTM technology both IP3O & NF are kept virtually flat while gain is backed off, enhancing SNR significantly under high level interferer conditions, and greatly benefiting 2G/3G/4G Multi- FlatNoiseTTMM Carrier IF sampling receivers.
