Description

The SKY66399-11 is a high-efficiency fully input/output

matched power amplifier (PA) with high gain and

linearity. The compact PA is designed for FDD and TDD

2G/3G/4G LTE small-cell base stations operating from

1900 to 2000 MHz.

The active biasing circuitry is integrated to compensate

PA performance over temperature, voltage, and

process variation.
