These are unused pins and not wired inside the package. They may be grounded or connected to adjacent pins.

6VPC1

VPC1 is the bias control pin for the stage 1 active bias circuit. An external series resistor is required for proper

setting of bias levels. 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.

8VPC2

VPC2 is the bias control pin for the stage 2 active bias circuit. An external series resistor is required for proper

setting of bias levels. 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

Output power detector voltage. Load with > 10K ohms for best performance

3

RFIN

RF input pin. This is DC grounded internal to the IC. Do not apply voltage to this pin.

12,14

RFOUT

RF output pin. This is also another connection to the 2nd stage collector.

16

VC2

2nd stage collector bias pin. Apply 3.0 to 5.0V to this pin.

18

VC1

1st stage collector bias pin. Apply 3.0 to 5.0V to this pin.

20

Vbias

Active bias network VCC. Apply 3.0 to 5.0V 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 opti-

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

mended 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:
