Description

SKY66297-11 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 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 high-efficiency, pin-to-pin compatible

PA family supporting all 3GPP bands.

A block diagram of the SKY66297-11 is shown in Figure 1.

Table 1 lists the pin-to-pin compatible parts in the PA family. The

device package and pinout are shown in Figure 2. Signal pin

assignments and functional pin descriptions are described in

Table 2.
