SKY66186-11 Linear PA Block Diagram Description The SKY66186-11 is a high-linearity power amplifier (PA) with fully matched input/output and high gain. The compact 5 x 5 mm PA is designed for FDD 3G/4G LTE small cell base stations operating from 728 to 768 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation as well as an...
