描述 Description

The SKY66318-11 is a highly efficient, wide instantaneous

bandwidth, fully input/output matched power amplifier (PA) with

high gain and linearity. The compact 5 × 5 mm PA is designed for

FDD and TDD 4G LTE and 5G systems operating from 3300 to

3600 MHz. The active biasing circuitry is integrated to

compensate PA performance over temperature, voltage, and

process variation.

The SKY66318-11 is part of a high-efficiency, pin-to-pin

compatible PA family supporting major 3GPP bands.

A block diagram of the SKY66318-11 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.
