Product Description
RFMD’s SGB-2233 is a high performance SiGe HBT MMIC amplifier utilizing a Dar-
lington 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 3Vto5V supply the SGB-2233 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-2233
product is designed for high linearity 3V gain block applications that require small
size and minimal external components. It is on chip matched to 50Ω and an exter-
Optimum Technology nal bias inductor choke is required for the application band.

Description
These are no connect pins. Leave them unconnected on the PC board.
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.
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.
