Gain Step Accuracy
LT5554 internal input signal coupling to the transcon-
ductance amplifier inputs across the 4dB step attenuator
increases with frequency. The gain step error is higher
when the LT5554 gain update changes the input attenua-
tor tap (PG5, PG6 transitions) and this error is frequency
dependent.
Gain error is ‘compressive’, effectively reducing LT5554
gain range. Therefore, it is possible to skip one gain

code whenever PG5, PG6 transitions are involved in or-
der to preserve high-frequency monotonic behavior for
0.125dB steps.
Linearity and Noise Performance Throughout the
Gain Range
The LT5554’s Noise and Linearity performance across
the 16dB gain range at 100MHz with ROUT = 100 and
RSADC = 50Ω is shown in Figures 10 through 13.
