Abstract
Disclosed herein are apparatus and methods for antenna sharing in a mobile device. In certain configurations, a mobile device includes a switching circuit that controls access of a plurality of transceivers to a plurality of antennas. The switching circuit includes a multi-pole multi-throw switch and a single-pole multi-throw switch, and has a first mode in which the switching circuit electrically connects a WiFi transceiver to a first antenna via a first transmit signal pathway through the multi-pole multi-throw switch. The switching circuit also has a second mode in which the switching circuit electrically connects the WiFi transceiver to a second antenna via a second transmit signal pathway through both the multi-pole multi-throw switch and the single-pole multi-throw switch. The multi-pole multi-throw switch includes an insertion loss component along the first transmit signal pathway to substantially match a total insertion loss of the first and second transmit signal pathways.
