5150 to 5925 MHz High-Efficiency 4 W Power Amplifier

Please note: SKY66288-11 is being discontinued and is not recommended for new designs.

The SKY66288-11 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 the unlicensed spectrum of LTE-advanced small-cell base stations operating from 5150 to 5925 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation.

The SKY66288-11 is part of the high-efficiency, pin-to-pin compatible PA family supporting all 3GPP bands.
