Description

The SKY66522-11 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 5G NR and 4G LTE systems

operating from 2300 to 2690 MHz.

The active biasing circuitry is integrated to compensate

PA performance over temperature, voltage, and process

variation.

The SKY66522-11 is part of high-efficiency, pin-to-pin

compatible PA family supporting major 3GPP bands.

A block diagram of the SKY66522-11 is shown in Figure

1. Table 1 lists the pin-to-pin compatible parts in the

PA family.
