ANTENNA INTERFACE CIRCUIT, DATA CARD, ANTENNA CONNECTION CONTROL METHOD, AND APPARATUS

An antenna interface circuit can improve MIMO performance of a system. The antenna interface circuit includes a main connector and a single-pole double-throw switch, where a common contact of the main connector is used as a terminal of a main receiver; a normally-closed contact of the main connector...

Zusammenfassung:	An antenna interface circuit can improve MIMO performance of a system. The antenna interface circuit includes a main connector and a single-pole double-throw switch, where a common contact of the main connector is used as a terminal of a main receiver; a normally-closed contact of the main connector is used as a terminal of a main antenna; a normally-open contact of the main connector is used as a terminal of an external antenna; a common contact of the single-pole double-throw switch is used as a terminal of a diversity receiver; a normally-closed contact of the single-pole double-throw switch is used as a terminal of a diversity antenna; a normally-open contact of the single-pole double-throw switch is connected to the normally-closed contact of the main connector; and when the common contact of the main connector is connected to the normally-open contact of the main connector, the common contact of the single-pole double-throw switch is connected to the normally-open contact of the single-pole double-throw switch.
