With a center frequency of 737.5 MHz, the filter achieves insertion loss as low as 1.5 dB typical in the Band 12 Rx passband and provides high out-of-band attenuation of 48 dB minimum (57 dB typical) against the Band 12 Tx frequencies. The 0402 footprint represents Murata's industry-leading miniaturization, enabling denser RF front-end layouts in modern smartphones. The R1X suffix denotes tape-and-reel packaging with 10,000 pieces per 178mm reel.","working_principle":"The SAFFB742MAA0F0AR1X uses Surface Acoustic Wave (SAW) technology to filter RF signals. An input interdigital transducer (IDT) converts the electrical RF signal into a mechanical acoustic wave that propagates along the piezoelectric substrate surface. The frequency-dependent propagation characteristics of the SAW and the geometry of the output IDT determine the filter passband. Frequencies within the passband (729-756 MHz) are efficiently converted back to electrical signals at the output, while out-of-band frequencies are not phase-matched and are attenuated. The 5-pin unbalanced configuration simplifies impedance matching and PCB routing compared to balanced designs.","pin_description":"\n
