SGC-4386Z_1 Datasheet, PDF (1/5 Pages) SIRENZA MICRODEVICES – 50-4000 MHz Active Bias Silicon Germanium Cascadable Gain Block

SGC-4386Z
Product Description
Sirenza Microdevices’ SGC-4386Z is a high performance SiGe HBT MMIC
amplifier utilizing a Darlington configuration with a patented active bias
50-4000 MHz Active Bias Silicon
network. The active bias network provides stable current over temperature _{Germanium Cascadable Gain Block}
and process Beta variations. Designed to run directly from a 3V supply, the
SGC-4386Z does not require a dropping resistor as compared to typical
Darlington amplifiers. The SGC-4386Z is designed for high linearity 3V gain
block applications that require small size and minimal external components.
It is internally matched to 50 ohms.
