Description

The SKY66524-11 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 3300 to 3800 MHz.

The active biasing circuitry is integrated to compensate

PA performance over temperature, voltage, and

process variation.

The SKY66524-11 is part of a pin-to-pin compatible

family of high efficiency PAs supporting major 3GPP

bands.

A block diagram of the SKY66524-11 is shown in

Figure 1. Table 1 lists the pin-to-pin compatible PA

family.
