The SKY66289-11 is a high-efficiency fully input/output matched power amplifier (PA) with high gain and linearity. The compact 5 x 5 mm PA is designed for FDD and TDD 2G/3G/4G LTE small cell base stations operating in two frequency ranges: 791 to 821 and 750 to 850 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation.
