GENERAL PERFORMANCE

Using the application circuit shown in Figure 24. Supply voltage (VDD) = 21 V, paddle temperature (TPADDLE) = 35°C, source impedance (ZS) =

load impedance (ZL) = 75 Ω, and DC current (IDD) = 540 mA, unless otherwise noted. Device performance is similar at 24 V.

1 The slope is defined as the delta of the gain at the start frequency and the gain at the stop frequency.

2 Flatness is defined as the maximum deviation from a linear best-fit of the gain in the frequency range of operation.
