Port Configuration and Functions

Port Diagram

The port diagram of the AMM-9893CH is shown below. There are two sets of DC pads, one on the North and one on the South edge of the die. They perform identical functions and are internally connected on the die. They are provided for convenience in bias routing and only one pad of each type needs to be connected.

Port Functions

Port	Function	Description
GND	Ground	Bottom side of the die must be connected to a DC/RF ground with high thermal and electrical conductivity. There is no need to bond to the Gnd pads on the top of the die.
RF In	RF Input	The amplifier’s RF Input pad, this pad has an internal DC blocking capacitor and is RF matched to 50 Ohms.
RF Out	RF Output	The amplifier’s RF Output pad, this pad has an internal DC blocking capacitor and is RF matched to 50 Ohms.
VD1	Positive DC Supply Voltage	This pad provides DC power to the drain of the first stage of the amplifier. DC voltage at this pin should be set to 3.5V for normal operation.
VD2	Positive DC Supply Voltage	This pad provides DC power to the drain of the second stage of the amplifier. DC voltage at this pin should be set to 3.5V for normal operation.
VD3	Positive DC Supply Voltage	This pad provides DC power to the drain of the third stage of the amplifier. DC voltage at this pin should be set to 3.5V for normal operation.
VD4	Positive DC Supply Voltage	This pad provides DC power to the drain of the fourth stage of the amplifier. DC voltage at this pin should be set to 3.5V for normal operation.
VG12	Gate Bias Voltage	This pad provides DC bias to the gates of stages 1 and 2 of the amplifier. This pin requires a negative bias voltage for normal operation. The drain current Id of the amplifier will be controlled by the voltage applied to this pin. As this voltage becomes more positive, drain current will increase. For normal operation, the voltage on this pin should be the same as Vg34 and set to produce a drain current of 350mA.
VG34	Gate Bias Voltage	This pad provides DC bias to the gates of stages 3 and 4 of the amplifier. This pin requires a negative bias voltage for normal operation. The drain current Id of the amplifier will be controlled by the voltage applied to this pin. As this voltage becomes more positive, drain current will increase. For normal operation, the voltage on this pin should be the same as Vg12 and set to produce a drain current of 350mA.

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 Supply Voltage (Vd)	4	V
Gate Supply Voltage (Vg)	-1.5	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
Positive Drain Supply Current (Id) (with RF Input)	450	mA
RF Input Power	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.
