Port Functions

Port	Function	Connector Type	Description
GND	Ground	-	Exterior housing must be connected to a DC/RF ground potential with high thermal and electrical conductivity.
RF In	RF Input	1.85F	This is the RF Input port of the amplifier. It is internally DC blocked and RF matched to 50 Ω.
RF Out	RF Output	1.85M	This is the RF Output port of the amplifier. It is internally DC blocked and RF matched to 50 Ω.
Vd	Drain Supply Pin	-	The Vd pin supplies drain voltage to the amplifier IC. Apply gate voltage Vg before applying drain voltage.
Vg	Gate Bias Pin	-	The Vg pin supplies negative control voltage to the amplifier and controls the amplifier gain. The user should apply between 0.4V and -0.6V to Vg pad before applying positive DC voltage to Vd port. Lower (more negative) voltages on Vg pad will result in lower drain current and lower small signal gain.
