SGC-6489Z Datasheet, PDF (1/5 Pages) SIRENZA MICRODEVICES – 50-3500 MHz Silicon Germanium Active Bias Gain Block

Preliminary Information
Product Description
SGC-6489Z Pb RoHS Compliant
& Green Package
Sirenza Microdevices’ SGC-6489Z is a high performance SiGe HBT MMIC ^{50-3500 MHz Silicon Germanium}
amplifier utilizing a Darlington configuration with an active bias network. The _{Active Bias Gain Block}
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.
