851 – 894 MHz Linear Power Amplifier: SKY66185-11

The SKY66185-11 is an 851 – 894 MHz high-linearity lower amplifier designed for FDD 3G/4G LTE small cell base stations that operate within the 851 – 984 MHz frequency range. It is also useful for active distributed antenna systems, cellular repeaters, and driver amplifiers. The amplifier features fully matched input/output, high gain, and an active biasing circuitry that is integrated to compensate its performance over temperature, voltage, and process variation.
