Description
Supply voltage for the first stage transistor. The configuration as shown on the application schematic is required for opti-
mum RF performance.
Bias control pin for the active bias network. Recommended configuration is shown in the application schematic.
RF input pin. This pin requires the use of an external DC-blocking capacitor as shown in the application shcematic.
Bias control pin for the active bias network for the second stage. The recommended configuration is shown in the appli-
cation schematic.
RF output and bias pin. Bias should be supplied to this pin through an external RF choke. Because DC biasing is present
on this pin a DC-blocking capacitor should be used in most applications. (See application schematic.) The supply side of
the bias network should be well bypassed. An output matching network is necessary for optimum performance.
Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for thermal and
RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern.
