Function
Description
VC1 VC1 is the supply voltage for the first stage transistor. The configuration as
shown on application schematic is required for optimum RF performance.
Vbias
Vbias is the bias control pin for the active bias network. Recommended
configuration is shown in the Application Schematic.
RF In
RF input pin. This pin requires the use of an external DC blocking capacitor as
shown in the Application Schematic.
VPC2
VPC2 is the bias control pin for the active bias network for the second stage.
The recommended configuration is shown in the Application Schematic.
RF Out/VC2
RF output and bias pins. 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.
Gnd
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 (page 9).

Operation of this device beyond any one of these limits
may cause permanent damage. For reliable continuous
operation, the device voltage and current must not exceed
the maximum operating values specified in the table on
page one.
Bias Conditions should also satisfy the following
expression:
ICCVCC (max) < (TJ - TL)/Rth,j-l
