GENERAL DOWNSTREAM PERFORMANCE

See the application circuit in Figure 31. Supply voltage (VDD) = 8.0 V, supply current (IDD) = 375 mA, paddle temperature (TPADDLE) = 35 °C, and

source impedance (ZS) = load impedance (ZL) = 75 Ω, unless otherwise noted.

Using the downstream applications circuit with passive

biasing, (VDD) = 8.0 V (see the Downstream Applications

Circuit with Passive Biasing section); can be adjusted

between 200 mA and 450 mA (see the Supply Voltage and

Bias Current section)

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.
