Port Configuration and Functions

Port Functions

Port	Function	Description	DC Equivalent Circuit
1-3, 5-8, 11-15, 17-22, 24	Non-connect (NC)	These pins are not internally connected. Datasheet performance is measured with these pins connected to ground.	-
Paddle	Ground	Ground pad should be connected to RF/DC ground with high electrical and thermal conductivity.
Pin 10	Off-Chip Cap Port 1	Pin 10 provides additional off chip bypass capacitance. A 0.1uF capacitor is recommended.
Pin 16	Drain Supply / RF Output	Pin 16 serves as the RF output and drain voltage supply pin for the amplifier. DC voltage is applied through an external choke inductor or bias-tee. The nominal DC voltage at this pin should be set to +6V. This pin is internally RF matched to 50 Ohms and requires an external DC blocking capacitor.
Pin 23	Off-Chip Cap Port 2	Pin 23 provides additional off chip bypass capacitance. A 100pF + 0.1uF capacitor combination is recommended.
Pin 4	RF Input	Pin 4 is the amplifier’s RF Input pin. It is RF matched to 50 Ω and requires an external DC blocking capacitor.
Pin 9	Positive bias	Pin 9 provides a required positive bias which supplies the current mirror. A higher voltage results in a higher current draw through the VD / RF Out port. This port should be set to +3V for normal operation.

Specifications

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If 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

Parameter	Maximum Rating	Unit
Bias Current (Ib)	10	mA
Bias Voltage (Vb)	6.5	V
Drain Current (Id) (RF Applied)	120	mA
Drain Supply Voltage (Vd)	8.5	V
Maximum Operating Temperature for MTTF > 1E6 hours	85	°C
Maximum Storage Temperature	125	°C
Minimum Operating Temperature for MTTF > 1E6 hours	-40	°C
Minimum Storage Temperature	-65	°C
RF Power Handling	23	dBm

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.
