NS
RFMD’s SGB-4333 is a high performance SiGe HBT MMIC amplifier utilizing a Darlington configuration with an active bias network. The active bias network provides
stable current over temperature and process Beta variations. Designed to run
directly from a 3 V to 5 V supply the SGB-4333 does not require a drop resistor as
compared to typical Darlington amplifiers. This robust amplifier features a Class 1C
ESD rating, low thermal resistance, and unconditional stability. The SGB-4333
product is designed for high linearity 3 V gain block applications that require small
size and minimal external components. It is on chip matched to 50 Ω and an external bias inductor choke is required for the application band.

RF input pin. A DC voltage should not be connected externally to this pin
An extra ground pin that is connected to the backside exposed paddle. Connection is optional.
RF Output pin. Bias is applied to the Darlington stage thru this pin.
NS
This pin sources the current from the active bias circuit. Connect to pin 10 thru an inductor choke.
This is Vcc for the active bias circuit.
The backside exposed paddle is the main electrical GND and requires multiple vias in the PC board to GND. It is also the
main thermal path.
