DATASHEET Dual Intermediate Frequency Digital Variable Gain Amplifier IDTF1240NBGI GENERAL DESCRIPTION The IDTF1240 (0.5 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 IDTF1240 IF VGA improves system 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-Carrier IF sampling receivers.
