SIRENZA SGC

SGC-4486Z
Product Description
Sirenza Microdevices’ SGC-4486Z is a high performance SiGe HBT MMIC
amplifier utilizing a Darlington configuration with a patented active bias
network. The active bias network provides stable current over temperature
and process Beta variations. Designed to run directly from a 3V supply, the
SGC-4486Z does not require a dropping resistor as compared to typical
Darlington amplifiers. The SGC-4486Z is designed for high linearity 3V gain
block applications that require small size and minimal external components.
It is internally matched to 50 ohms.

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.
Caution: ESD sensitive
Appropriate precautions in handling, packaging
and testing devices must be observed.
Bias Conditions should also satisfy the following expression:
