Description

The SKY66319-11 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 TDD 4G LTE

and 5G systems operating from 4400 to 5000 MHz.

The active biasing circuitry is integrated to compensate

PA performance over temperature, voltage, and

process variation.

The SKY66319-11 is part of high-efficiency, pin-to-pin

compatible PA family supporting major 3GPP bands.

A block diagram is shown in Figure 1. The device

package and pinout 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.
