SKY66522-11 High-Efficiency Power Amplifier IC Chip with 36.5 dB Gain and 2300MHz To 2690MHz Frequency Range

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 a high-efficiency, pin-to-pin compatible PA family supporting major 3GPP bands.
