The SKY66317-11 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 2496 to 2690 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation. The SKY66317-11 is part of high-efficiency, pin-to-pin compatible PA family supporting major 3GPP bands. A block diagram of the SKY66317-11 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.
