Epcos has developed the all-in-one front-end module for Bluetooth and WLAN applications to the 802.11 b/g/n standard. With an insertion height of 1.4 mm, it has a footprint of 4.5 x 3.2 mm² on the circuit board. The module integrates a WLAN power amplifier, a WLAN-Bluetooth switch, a receive balun, and a bias circuit with ESD protection.

In addition, the coexistence filter allows simultaneous operation of WLAN and Bluetooth applications with all mobile phone standards. The LTCC module, with the designation D6101, thus provides all the required functions between WLAN or Bluetooth RF transceivers and the antenna.
