Port Configuration and Functions

Port Diagram

Diagram of the port configuration for ADM-8344PC

Port Functions

Port	Function	Connector Type	Description
GND	Ground	-	Housing or ground lug must be connected to a DC/RF ground potential with high thermal and electrical conductivity.
RF In	RF Input	SMAF	This is the amplifier’s RF Input port. It is RF matched to 50 Ω and has built-in DC blocking capacitors.
RF Out	RF Output	SMAM	This is the amplifier’s RF Output port. It is RF matched to 50 Ω and has built-in DC blocking capacitors.
Vd	Drain Supply Pin	-	The VD pin supplies DC voltage to the drain of the amplifier IC. This pin is nominally set at +5V.
Vg	Gate Bias Pin	-	The VG pin provides a required positive bias which supplies the current mirror. A higher voltage results in a higher current draw through the RF Out port. This pin is nominally set at +5V.

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
Drain Current (Id) (RF Applied)	130	mA
Drain Supply Voltage (Vd)	8.5	V
Gate Current (Ig)	10	mA
Gate Supply Voltage (Vg)	6.5	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	-55	°C
RF Power Handling	15	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.
