Characteristically, the RXMC distributes the full RX frequency b<strong>and</strong> to all outputs. The net gain or loss isoften the same <strong>for</strong> all outputs but unequal division is also a design option where the RXMC servesreceivers with differing input level requirements or where the signal will be further divided be<strong>for</strong>e reachingthe receivers.For applications with few outputs – usually just two – a power splitter without LNA is sometimes used.6.7.10 INTEGRATED DEVICES — SAME BAND COMBINERThe generic term Same B<strong>and</strong> Combiner (SBC) refers to a device that passes uplink <strong>and</strong> downlink signals,incorporating some combination of same b<strong>and</strong> transmit combining <strong>and</strong>/or receive signal distribution usingany of the methods described above, excluding power amplifiers. The configurations vary withapplication.<strong>4G</strong> <strong>Americas</strong> <strong>MIMO</strong> <strong>and</strong> <strong>Smart</strong> <strong>Antennas</strong> <strong>for</strong> <strong>Mobile</strong> Systems – October 2012 – All Rights Reserved110
