RFMD’s 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.

Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical performance or functional operation of the device under Absolute Maximum Rating conditions is not implied.

*Note: Load condition ZL = 50
Operation of this device beyond any one of these limits may cause permanent damage. For reliable continuous operation, the device voltage and current must not
exceed the maximum operating values specified in the table on page one.
Bias Conditions should also satisfy the following expression:
IDVD < (TJ - TL)/RTH, j - l and TL = TLEAD

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.
