Description
SKY66291-11 is a high-efficiency fully input/output matched
power amplifier (PA) with high gain and linearity. The compact
5  5 mm PA is designed for FDD and TDD 2G/3G/4G LTE small
cell base stations operating from 1805 to 1880 MHz. The active
biasing circuitry is integrated to compensate PA performance over
temperature, voltage, and process variation.
The SKY66291-11 is part of high-efficiency, pin-to-pin compatible
PA family supporting all 3GPP bands.
A block diagram of the SKY66291-11 is shown in Figure 1. The
device package and pinout are shown in Figure 2. Table 1 lists
the pin-to-pin compatible parts in the PA family. Signal pin
assignments and functional pin descriptions are described in
Table 2.
