750 to 770 MHz Linear Power Amplifier

The SKYA21050 is a high-linearity power amplifier (PA) with fully matched input/output and high gain. The compact 5 x 5 mm PA is designed for the Japan market 760 MHz vehicle-to-vehicle and infrastructure communication based on the ARIB STD-T109.

The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation as well as an internal coupler for power monitoring.
