Abstract: An apparatus is disclosed with an absorptive filter. In an example aspect, an apparatus has a filter including a first filter port and a second filter port. The filter also includes a hybrid coupler, a signal combiner, a first filter unit, and a second filter unit. The hybrid coupler includes a first hybrid port, a second hybrid port, and a third hybrid port, with the first hybrid port coupled to the first filter port. The signal combiner is coupled to the second filter port. The first filter unit is coupled between the second hybrid port and the signal combiner. The second filter unit is coupled between the third hybrid port and the signal combiner.

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.
