Description
These are no connect pins. Leave them unconnected on the PC board.
RF input pin. A DC voltage should not be connected externally to this pin
An extra ground pin that is connected to the backside exposed paddle. Connection is optional.
RF Output pin. Bias is applied to the Darlington stage thru this pin.
This pin sources the current from the active bias circuit. Connect to pin 10 thru an inductor choke.
This is Vcc for the active bias circuit.
The backside exposed paddle is the main electrical GND and requires multiple vias in the PC board to GND. It
is also the main thermal path.

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.
