Providing the required ability of simultaneously transmitting and receiving RF signals, duplexers are one of the key components in the well established 3G (W)-CDMA communication systems. For mobile terminals, duplexers in micro-acoustic filter technology have been used for several years. Generally, these duplexers are composed of two band pass filters and additional passive elements to improve the electrical performance. Based on the prototypical packaging approach which has been used for the… CONTINUE READING
