Description

The SKY66295-21 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 800 to 900 MHz. The active

biasing circuitry is integrated to compensate PA performance over

temperature, voltage, and process variation.

The SKY66295-21 is part of high efficiency, pin-to-pin compatible

PA family supporting all 3GPP bands.

A block diagram of the SKY66295-21 is shown in Figure 1. The

device package and pinout for the 16-pin device 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.
