Technical Specifications

The QM13126 operates at a specific frequency band (which varies depending on the specific application, but typically within cellular bands). It exhibits very low insertion loss in the passband and high attenuation in the stopband. The filter's impedance is typically 50 ohms. The power handling capability is high, enabling it to be used in transmitters. The package type is a surface-mount package designed for automated assembly. The operating temperature range extends from -40°C to +85°C. Consult the Qorvo datasheet for detailed specifications regarding the center frequency, bandwidth, insertion loss, return loss, attenuation, and power handling capabilities. Detailed S-parameter data is crucial for designing the filter into a specific application.

BAW filters like the QM13126 offer superior performance compared to SAW (Surface Acoustic Wave) filters in terms of power handling and temperature stability, making them ideal for demanding wireless applications.
