EDS-104608 Rev C
Preliminary
Sirenza Microdevices' SZM-3066Z is a high linearity class AB
Heterojunction Bipolar Transistor (HBT) amplifier housed in a
low-cost surface-mountable plastic Q-FlexN multi-chip module
package. This HBT amplifier is made with InGaP on GaAs
device technology and fabricated with MOCVD for an ideal
combination of low cost and high reliability.
This product is specifically designed as a final or driver stage
for 802.16 equipment in the 3.3-3.8 GHz bands. It can run from
a 3V to 6V supply. The external output match and bias adjust-
ability allows load line optimization for other applications or
over narrower bands. It features an output power detector, on/
off power control and high RF overdrive robustness. This prod-
uct features a RoHS compliant and Green package with matte
tin finish, designated by the `Z' suffix.

29, 31, 33, 34, 39, 40
NC
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.
1,10, 21, 30
GND
These pins are internally grounded inside the package to the backside ground paddle. It is recom-
mended to also ground them external to the package to achieve the specified performance.
2
VC1
This is the collector of the first stage.
3
VBIAS12
This is the supply voltage for the active bias circuit of the 1st and 2nd stages.
4
NC
This pin is not connected inside the package, but it is recommended to connect it to GND to
achieve the specified performance.
6
RFIN
This is the RF input pin. It is DC grounded inside the package. Do not apply DC voltage to this pin.
8
VPC1
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.
9
VPC2
Power up/down control pin for the 2nd 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.
13, 38
VC2A, VC2B
These two pins are connected internal to the package to the 2nd stage collector. To achieve spec-
ified performance, the layout of these pins should match the Recommended Land Pattern, pg. 9.
14,15, 36, 37
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
VB3A, VB3B
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, pg. 9.
19
VPC3
Power up/down control pin for the 3rd 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 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
RFOUT
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.
