Abstract:
An apparatus including: a plurality of amplifiers having a plurality of output ports, respectively, the plurality of amplifiers configured to amplify radio frequency (RF) signals received from at least one antenna; a plurality of demodulators configured to receive the amplified RF signals at a plurality of input ports, respectively, the plurality of demodulators configured to downconvert the received RF signals; and a plurality of switches configured to couple selected output ports of the plurality of amplifiers to selected input ports of the plurality of demodulators, wherein each switch of the plurality of switches is configured such that at least one of the plurality of output ports of the plurality of amplifiers is selectively coupled to any of multiple input ports of the plurality of input ports of the plurality of demodulators.
