Abstract:
1. A switched multiplexer configured to combine a quantity of signal paths each covering a sub-octave in a frequency range, the switched multiplexer being configured to remove transmitter harmonics of an input signal to create a stable output impedance across the frequency range of from f min to f max , the switched multiplexer comprising: a transmit switch configured to receive the input signal and to generate a transmit signal in response thereto; a plurality of diplexers connected in parallel with one another, each one of the diplexers being comprised of a non-adjacent pair of the signal paths connected in parallel with one another, each one of the diplexer terminating at a resistive attenuator except for the diplexer containing the signal path covering the highest pass band; and a power combiner connected to the diplexers and being configured to sum inputs received therefrom and generate a substantially stable multi-octave output impedance signal in response thereto.
