描述 Description

The SKY66391-12 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 1800 to 1900 MHz. The active

biasing circuitry is integrated to compensate PA performance over

temperature, voltage, and process variation.

The SKY66391-12 is part of a high-efficiency, pin-to-pin

compatible PA family supporting all 3GPP bands. Table 1 lists the

pin-to-pin compatible parts in the PA family.

A block diagram of the SKY66391-12 is shown in Figure 1. The

device package and pinout for the device are shown in Figure 2.

Signal pin assignments and functional pin descriptions are

described in Table 2.
