Sirenza Microdevices’ SGC-6489Z 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 5V supply, the SGC-6489Z
does not require a dropping resistor as compared to traditional Darlington
amplifiers. The SGC-6489Z product is designed for high linearity 5V gain
block applications that require small size and minimal external components.
It is internally matched to 50 ohms.

Mounting Instructions
1. Solder the copper pad on the backside of the
device package to the ground plane.
2. Use a large ground pad area with many plated
through-holes as shown.
3. We recommend 1 or 2 ounce copper. Measurements
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.
