EPCOS has developed the most compact all-in-one front-end module for Bluetooth and WLAN applications to the 802.11 b/g/n standard. According to EPCOS, the LTCC based front-end module is the world’s smallest for WLAN and Bluetooth. With an insertion height of 1.4 mm, it has a footprint of only 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, designated D6101, provides all the required functions between WLAN or Bluetooth RF transceivers and the antenna. It consequently reduces the development time for terminals while occupying less space.
