Abstract
(EN)
Provided is a switched multiplexer configured to combine first, second, third and fourth signal paths each covering a sub-octave in a frequency range of from about 2 to about 18 GHz and to remove transmitter harmonics of an input signal to create a stable output impedance across the frequency range. The switched multiplexer comprises a transmit switch, a first diplexer and a power combiner. The first diplexer is connected in parallel with a second diplexer. The first diplexer comprises first and second signal paths. The second diplexer comprises third and fourth signal paths. Each one of the first, second and third signal paths include respective ones of the first switch, a second switch and a third switch, each interconnected to respective ones of a first signal path high-pass filter, second signal path low-pass filter and third signal path low-pass filter by respective ones of a first, second and third filter. Each one of the first, second and third filters have a respective filter capability in the range of from about 6-10.4 GHz, 2-3.5 GHz, and 3.5-6 GHz.
