Abstract:
1. A receiver, comprising: selection circuitry having a plurality of inputs, wherein each input of the plurality of inputs is coupled to a separate signal path of a plurality of signal paths, each signal path receiving a RF signal from among a plurality of RF signals in separate frequency bands, wherein the selection circuitry selectively transmits a RF signal received on an input of the plurality of inputs to an output of the selection circuitry, wherein the selection circuitry comprises a first plurality of transistors, each receiving a separate RF signal from among the plurality of RF signals on a control node and outputting a received RF signal on a current electrode, the current electrodes of all transistors being connected in parallel; and a mixer core coupled to the selection circuitry receiving the selectively transmitted RF signal and reference signals, the mixer combining the selectively transmitted RF signal and reference signals to generate output signals.
