Description

The SKY66525-11 is a highly efficient, wide

instantaneous bandwidth, fully input/output matched

power amplifier (PA) with high gain and linearity. The

compact 5 x 5 mm PA is designed for 5G NR systems

operating from 3450 to 4200 MHz.

The active biasing circuitry is integrated to compensate

PA performance over temperature, voltage, and

process variation.

The SKY66525-11 is part of a pin-to-pin compatible

family of high efficiency PAs supporting major 3GPP

bands.

A block diagram of the SKY66525-11 is shown in

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

family.
