Claim:
1. A mobile communication system comprising: a housing comprising an interior region and an exterior region; a display coupled to the housing; a processing device provided within the interior region of the housing; a filter diplexer module comprising an antenna coupled to the rf transmit module and the rf receive module; an antenna control device coupled to the receive path and the transmit path and configured to select either the receive path or the transmit path, wherein the antenna control device is coupled to the filter diplexer module; a power amplifier module coupled to the processing device and the filter diplexer module, the power amplifier module being configured on the transmit path and the receive path, wherein the power amplifier module comprises a plurality of communication bands, each communication band having a power amplifier, wherein the one or more diplexer filter devices are configured to one or more of the plurality of communication bands; a band-to-band isolation between any pair of adjacent communication bands in the plurality of communication bands characterizing the transmit filter such that a difference between a pass band to reject band as measured in relative decibels (dBc) is greater than 10 dBc and less than 100 dBc; an insertion loss characterizing the transmit filter, the insertion loss being less than 3 dB and greater than 0.5 dB; and a center frequency configured to define the pass band; wherein each single crystal acoustic resonator devices of the diplexer filter devices comprises:
