2490 to 2690 MHz High-Efficiency 4 W Power Amplifier

SKY66297-11 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 from 2490 to 2690 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation.

The SKY66297-11 is part of a high-efficiency, pin-to-pin compatible PA family supporting all 3GPP bands.
