Description

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

the application circuit to achieve the stated performance.

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.

This is the collector of the first stage.

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

A resistor is tied across these pins internal to the package.

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

Power up/down control pin for the 1st stage. An external series resistor is required for proper set-ting 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.

Power up/down control pin for the 2nd stage. Power down VPC2<1V for step attenuator function enable.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.

These two pins are connected internal to the package and connect to the 2nd stage collector. Toachieve specified perfor-

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

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

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

These are the connections to the base of the 3rd stage output device. To achieve specified perfor-mance, the layout of

these pins should match the Recommended Land Pattern.

Power up/down control pin for the 2nd 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.

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

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

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

Part Symbolization

The part will be symbolized with “SZM-2066Z” to designate it as a RoHS green compliant product. Marking designator will be

on the top surface of the package.
