Port Functions

Port	Function	Description	DC Equivalent Circuit
1,6	N/C	Pin 1 and Pin 6 are internally no-connects and should be connected to DC/RF ground.	-
2	RF Input	Pin 2 is the RF Input port of the amplifier. It is internally RF matched to 50 Ω and requires an external DC blocking cap.	-
3	Vg	Pin 3 is an external bias resistor connection. The gate is internally biased by the Vd supply, therefore a supply voltage should not be applied to Vg. The default resistor is 1kΩ shunt to GND.	-
4	Vb	Pin 4 is the current mirror DC voltage supply port that controls the drain current. The VB supply should be tied to the VD supply through an external supply. Increasing the current will increase OIP3 at the expense of efficiency. The default series resistor is 1.5kΩ to optimize gain, output power, and efficiency when VB and VD are both tied to 5V.	-
5	Vd / RF Out	Pin 5 is the RF Output port and is also the Vd port providing the main power supply to the amplifier. This pin is DC coupled and requires an external bias-T or discrete choke and DC blocking capacitor. This port is RF matched to 50 Ω. DC voltage at this pin should be set to 5V for normal operation.	-
Paddle	Gnd	Package ground paddle must be connected to a DC/RF ground potential with high thermal and electrical conductivity.	-

Specifications

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If any one of these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device.

Drain Supply Voltage (Vd)	6.5	V
Maximum Operating Temperature for MTTF > 1E6 hours	85	°C
Maximum Storage Temperature	125	°C
Max Junction Temperature for MTTF of >1E6 hours	175	°C
Max Power Dissipation for MTTF of > 1E6 hours	1	W
Minimum Operating Temperature for MTTF > 1E6 hours	-40	°C

Recommended Operating Conditions

The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.
