Overview

The IDT F1240NBGI8 IF VGA featuring FlatNoise™ technology improves system SNR, especially at lower gain settings. By keeping both IP3O & NF flat while gain is backed off, the system SNR is improved significantly under high level interferer conditions, especially when considering alias noise in an IF sampling receiver. The fast-settling, parallel mode gain step of 0.50 dB coupled with the excellent differential non-linearity allow for SNR to be maximized further by targeting the minimum necessary gain in small, accurate increments. The matched output does not require a terminating resistor, thus the gain and distortion performance are preserved when driving Bandpass Anti-Alias filters.
