Thanks to the very good separation of the Tx and Rx signals, the new EPCOS duplexer can be combined with power-saving envelope tracking power amplifiers without any additional prefiltering. This significantly simplifies the design of the front end, leading to major cost benefits. A further advantage of the new duplexer is its low insertion loss of only 1.9 dB in the Tx path, which leads to a further power saving and thus a longer operating life of the battery. Applications are smartphones, tablets as well as LTE USB sticks for notebooks.
