Claim Text:
1. An apparatus comprising: a first N-plexer arranged to perform frequency multiplexing, the first N-plexer comprising: a shared amplification path having an input node and an output node, wherein the input node is coupled to the third port of the first N-plexer, the shared amplification path comprising: a second N-plexer arranged to perform frequency demultiplexing, the second N-plexer comprising: a mixer configured to multiply a local oscillator (LO) signal with signal(s) comprising the one or more amplified signals of the RF band to generate a plurality of signals including the one or more signals of the IF band; and an IF filter arranged in a signal path between an output of the mixer and the second port of the first N-plexer, wherein the IF filter is configured to filter the plurality of signals to extract the one or more signals of the IF band and to provide the one or more signals of the IF band to the first N-plexer.
