SGB-2233

Preliminary Data Sheet Product Description Sirenza Microdevices’ SGB-2233 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 3V to 5V supply the SGB-2233 does not require a drop resistor as compared to typical Darlington amplifiers. This robust amplifier features a Class 1C ESD rating, low thermal resistance , and unconditional stability. The SGB-2233 product is designed for high linearity 3V gain block applications that require small size and minimal external components. It is on chip matched to 50 ohm and an external bias inductor choke is required for the application band.
