Same-band combiner using dual-bandpass channel filters

摘要

Various embodiments relate to an apparatus and related method for transmission and reception of a plurality of a carrier signals comprising one or more dual-band channels through a same-band combiner. A device such as a base station may include a same-band combiner that comprises a plurality of dual-bandpass filters and a combining element to transmit and receive the carrier signal. Each of the dual-bandpass filters may transmit and receive a channel, with each dual-bandpass filter including separate reception and transmission passbands for the separate frequencies in the dual-band channel. The combining element may separate and combine the one or more dual-band channels, with each of the dual-bandpass filters connected in parallel processing separate dual-band channels.
