Systems, apparatuses, and methods for transceiver filters

A transceiver apparatus connectable to at least one filter, the transceiver apparatus comprising:

• a housing comprising:
• a transmitter,
• a receiver,
• a transceiver switch,
• a filter switch assembly,
• an antenna port,
• at least one filter of a receiver path,
• a filter send port of the receiver path, and
• a filter return port of the receiver path,
• wherein a transmitter path in the housing connects the transmitter to the antenna port and the receiver path in the housing connects the receiver to the antenna port,
• wherein the receiver path comprises an unfiltered path and a filtered path,
• wherein the at least one filter is positioned external to the housing and between the filter send port and the filter return port,
• wherein the filtered path connects the filter send port to the at least one filter and the at least one filter to the filter return port, and
• wherein one of the filter send port and the filter return port is antenna-side and the other of the filter send port and the filter return port is receiver-side,
• wherein the transmitter is isolated from each of the filter send port and the filter return port,
• wherein the filter switch assembly is configured to connect the receiver and the antenna port through (i) the at least one filter, or (ii) an unfiltered path isolated from each of the filter send port and the filter return port, and
• wherein the transceiver switch is configured to connect the antenna port to (i) the transmitter, or (ii) the receiver.

A method for filtering a signal comprising:

• switching, by a controller, in response to a first signal, a receiver disposed in a housing of a transceiver system from an unfiltered path connected to an antenna port disposed in the housing to a filtered path connected to the antenna port, a transmitter path in the housing connects a transmitter disposed in the housing to the antenna port and a receiver path in the housing connects the receiver to the antenna port, and wherein the receiver path comprises the unfiltered path and the filtered path;
• and
• switching, by a controller, in response to a second signal, the receiver from the filtered path to the unfiltered path,
• wherein the filtered path comprises a filter positioned external to the housing and between a filter send port of the filtered path and a filter return port of the filtered path, wherein the filtered path connects the filter send port to the filter and the filter to the filter return port, and
• wherein the filtered path is isolated from a transmitter of the transceiver system.
