NC

These are no connect (NC) pins and are not wired inside the package. It is recommended to connect them as shown

in the application circuit to achieve the stated performance.

1, 10,

21, 30

GND

These pins are internally grounded inside the package to the backside ground paddle. It is recommended to also

ground them external to the package to achieve the specified performance.

2VC1

This is the collector of the first stage.

3VBIAS12

This is the supply voltage for the active bias circuit of the 1st and 2nd stages.

4NC

This pin is not connected inside the package, but it is recommended to connect it to GND to achieve the specified per-

formance.

6RF IN

This is the RF input pin. It is DC grounded inside the package. Do not apply DC voltage to this pin.

8VPC1

Power up/down control pin for the 1st stage. An external series resistor is required for proper setting of bias levels

depending on control voltage. The voltage on this pin should never exceed the voltage on pin 3 by more than 0.5V

unless the supply current from pin 3 is limited <10mA.

9VPC2

series resistor is required for proper setting of bias levels depending on control voltage. The voltage on this pin should

never exceed the voltage on pin 3 by more than 0.5V unless the supply current from pin 3 is limited <10mA.

13, 38

the layout of these pins should match the Recommended Land Pattern.

14, 15,

C1A,C2A

C1B,C2B

These pins have capacitors across them internal to the package as shown in the below schematic. They are used as

tuning and RF coupling elements between the 2nd and 3rd stage.

16, 35

these pins should match the Recommended Land Pattern.

19

VPC3

Power up/down control pin for the 3rd stage. An external series resistor is required for proper setting of bias levels

depending on control voltage. The voltage on this pin should never exceed the voltage on pin 32 by more than 0.5V

unless the supply current from pin 33 is limited <10mA.

20

VDET

This is the output port for the power detector. It samples the power at the input of the 3rd stage.

23-28

RF OUT

These are the RF output pins and DC connections to the 3rd stage collector.

32

VBIAS3

This is the supply voltage for the active bias circuit of the 3rd stage.
