Description

Product Overview

The SAFFB742MAA0F0AR1X is a SAW (Surface Acoustic Wave) single filter manufactured by Murata Electronics, designed for LTE Band 12 and Band 13 receiver filtering in a 0402 (1.0 x 0.5 mm) ultra-compact package. With a center frequency of 737.5 MHz, this unbalanced 5-pin filter provides excellent insertion loss of 1.5 dB typical and high out-of-band attenuation up to 57 dB, making it ideal for multiband smartphone front-end modules.

Features

  • Ultra-compact 0402 footprint for high-density smartphone RF front-end design
  • Dual-band support for Band 12 and Band 13 LTE receiver paths
  • Low insertion loss of 1.5 dB typical for minimal receiver sensitivity degradation
  • High out-of-band attenuation up to 57 dB for excellent Tx rejection
  • 5-pin unbalanced configuration for simplified PCB layout

Applications

  • LTE smartphone Band 12/13 receiver front-end filtering

The SAFFB742MAA0F0AR1X from Murata is a SAW single filter designed for LTE Band 12 and Band 13 receiver paths in an ultra-compact 0402 (1.0 x 0.5 mm) 5-pin package. 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.

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 Name Type Function
1 IN RF Input Unbalanced RF signal input from antenna switch
2 GND Ground Ground connection for substrate shielding
3 OUT RF Output Filtered RF output to LNA/receiver
4 GND Ground Ground connection
5 GND Ground Ground connection
  • LTE smartphone Band 12 (700 MHz lower A) receiver path filtering between antenna switch and LNA
  • LTE smartphone Band 13 (700 MHz upper C) receiver path filtering for Verizon/AT&T networks
  • IoT gateway LTE modem Band 12/13 Rx filtering for North American deployments
  • Automotive telematics control unit LTE receiver front-end module
  • Tablet and laptop LTE module Band 12/13 receive filtering
