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, wherein the shared amplification path comprises an amplifier configured to amplify signals from at least both the first RF band and the first IF band; 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 first RF band to generate a plurality of signals including the one or more signals of the first IF band; a first controllable attenuator in a signal path downstream of the third port of the second N-plexer, wherein the first controllable attenuator is configured to set an overall gain of the one or more amplified signals of the first IF band; and a first IF filter arranged in a signal path between an output of the mixer and the second port of the first N-plexer, wherein the first IF filter is configured to filter the one or more signals of the first IF band and to provide the one or more signals of the first IF band to the first N-plexer.
