Abstract:
1. Front end circuitry comprising: a first duplexer configured to pass transmit signals about a first operating band between a first transceiver node and a first switching node and pass receive signals about a first portion of the first operating band between the first switching node and a second transceiver node, while attenuating other signals; a first receiver filter configured to pass receive signals about the first portion of the first operating band between a second switching node and a third transceiver node, while attenuating other signals; a second receiver filter configured to pass receive signals about a second portion of the first operating band between a third switching node and a fourth transceiver node, while attenuating other signals; a third receiver filter configured to pass receive signals about the second portion of the first operating band between a fourth switching node and a fifth transceiver node, while attenuating other signals; and front end switching circuitry coupled between each one of the switching nodes and at least four antenna nodes, the front end switching circuitry configured to place each one of the switching nodes in contact with a different one of the antenna nodes.
