Description
Supply voltage for the bias reference and control circuits. May be connected with VCC1 and VCC2 as long as V_CC
does not exceed 5.0V_DC in this configuration.
RF input, internally matched and DC block is provided.
Not connected. May be connected to ground.
First stage input bias voltage. This pin requires a regulated supply to maintain nominal bias current.
Second stage input bias voltage. This pin requires a regulated supply to maintain nominal bias current.
Third stage input bias voltage. This pin requires a regulated supply to maintain nominal bias current.
Power detector provides an output voltage proportional to the RF output power level.
RF output and bias for the output stage. Output is externally matched to 50 and needs DC block.
Second stage supply voltage.
First stage supply voltage.
Ground connection. The back side of the package should be connected to the ground plane through as short a
connection as possible, e.g., PCB vias under the device are recommended.
