Info

Characteristically, the RXMC distributes the full RX frequency band to all outputs. The net gain or loss isoften the same for 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 before 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 Band Combiner (SBC) refers to a device that passes uplink and downlink signals,incorporating some combination of same band transmit combining and/or receive signal distribution usingany of the methods described above, excluding power amplifiers. The configurations vary withapplication.4G Americas MIMO and Smart Antennas for Mobile Systems – October 2012 – All Rights Reserved110
