3550 to 4200 MHz Wide Instantaneous Bandwidth High-Efficiency Power Amplifier

The SKY66523-11 is a 200 MHz instantaneous bandwidth, fully input/output matched 30 dBm power amplifier (PA) with high gain and linearity. The compact 5 × 5 mm PA is designed for 5G NR systems operating from 3550 to 4200 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation.

The SKY66523-11 is part of high-efficiency, pin compatible PA family supporting major 3GPP bands.
