Abstract: In an example, an apparatus includes first and second antennas and a switched extractor coupled to the first antenna. The switched extractor includes an extractor configured to extract an extraction frequency band, a bypass line, and switching circuitry. The switching circuitry is configured to selectively establish a bypass signal path including the bypass line or a concurrent signal path including the extractor. The apparatus also includes first and second transceiver units (TRXUs) and a processor. The first TRXU is coupled to the first antenna via the switched extractor. The second TRXU is coupled to the first antenna via the switched extractor and coupled to the second antenna. The processor is configured to cause the switching circuitry to selectively connect the first TRXU to the first antenna via the bypass or the concurrent signal path based on the extraction frequency band and an operational frequency band associated with the first TRXU.

Abstract: Certain aspects of the disclosure related to communications apparatus provides isolation between wireless protocols when operating currently while incurring the additional insertion loss based on providing the isolation only when needed. In an aspect, an apparatus include a switched filter coupled to an antenna where the switched filter includes a filter and a bypass line along with switching circuitry configured to selectively establish a bypass signal path including the bypass line or a filtered signal path including the filter. The apparatus further includes a switched filter controller configured to cause the switching circuitry to selectively connect a transceiver unit to the antenna via the bypass signal path or via the filtered signal path based at least on a frequency band of a carrier signal and a bandwidth of the carrier signal.
