Pins are not used. May be grounded, left open, or connected to adjacent pin.

VPC1

VPC1 is the bias control pin for the stage 1 active bias circuit and can be run from 2.9V to 5V control. An

external series resistor is required for proper setting of bias levels depending on control voltage. Refer to

the evaluation board schematic for resistor value. To prevent potential damage, do not apply voltage to this

pin that is +1V greater than voltage applied to pin 20 (Vbias) unless Vpc supply current capability is less

than 10 mA.

7

VPC2

VPC2 is the bias control pin for the stage 2 active bias circuit and can be run from 2.9V to 5V control. An

external series resistor is required for proper setting of bias levels depending on control voltage. Refer to

the evaluation board schematic for resistor value. To prevent potential damage, do not apply voltage to this

pin that is +1V greater than voltage applied to pin 20 (Vbias) unless Vpc supply current capability is less

than 10 mA.

8

VPC3

VPC3 is the bias control pin for the stage 3 active bias circuit and can be run from 2.9V to 5V control. An

external series resistor is required for proper setting of bias levels depending on control voltage. Refer to

the evaluation board schematic for resistor value. To prevent potential damage, do not apply voltage to this

pin that is +1V greater than voltage applied to pin 20 (Vbias) unless Vpc supply current capability is less

than 10 mA.

10

Vdet

Ouput power detector voltage. Load with 10K-100K ohms to ground for best performance.

2,4

RFIN

RF input pins. This is DC grounded internal to the IC. Do not apply voltage to this pin. All three pins must be

used for proper operation.

12,13,14

RFOUT

RF output pin. This is also another connection to the 3rd stage collector

16

VC3

3rd stage collector bias pin. Apply 5V to this pin.

18

VC2

2nd stage collector bias pin. Apply 5V to this pin.

19

VC1

1st stage collector bias pin. Apply 5V to this pin.

20

Vbias

Active bias network VCC. Apply 5V to this pin.

EPAD

Gnd

Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for

optimum thermal and RF performance. Several vias should be located under the EPAD as shown in the rec-

ommended land pattern (page 5).

Caution: ESD Sensitive

Appropriate precaution in handling, packaging

and testing devices must be observed.

Operation of this device beyond any one of these limits may

cause permanent damage. For reliable continuous operation

the device voltage and current must not exceed the maximum

operating values specified in the table on page one.

Bias conditions should also satisfy the following expression:
