No picture available

TDK Corporation presents the new highly integrated EPCOS D5058 front-end module for smartphones. In addition to the conventional GSM bands at 850, 900, 1800 and 1900 MHz, it also covers WCDMA bands 1, 2, 4 and 5, as well as LTE bands 2, 4, 5 and 17. Apart from three conventional SAW filters and five duplexers, the module contains the band selection switches and decoders as well as an ESD protection circuit for up to 4 kV at the antenna output. This new front-end module thus offers the highest level of integration possible today.

In addition to its high integration density, the D5058 front-end module is characterized by highly compact dimensions of only 8.0 x 4.95 x 1.0 mm³. Depending on the band and filter, the insertion loss is between 1.2 and 3.8 dB.

These integrated EPCOS front-end solutions allow developers to implement smartphones and conventional mobile phones in the usual compact dimensions despite the integration of additional functions. In comparison with discrete solutions, EPCOS front-end modules permit the footprint on the board to be reduced by up to 40 percent.

Main features and benefits

  • Covers the most important GSM, WCDMA and LTE bands
  • Integration of three SAW filters and five duplexers
