MOBILE COMMUNICATION CIRCUITRY FOR THREE OR MORE ANTENNAS
First Claim
Patent Images
1. A communication system for at least three antennas, the communication system comprising:
- a first switch configured to communicate with a main low band signal at a first pole of the first switch and to communicate with a second low band signal at a second pole of the first switch;
a second switch configured to communicate with a main high band signal at a first pole of the second switch and to communicate with a second high band signal at a second pole of the second switch;
a first diplexer configured to communicate with a first antenna;
a second diplexer configured to communicate with a second antenna;
a third diplexer configured to communicate with a third antenna; and
wherein the first switch includes a first throw of the first switch in communication with the first diplexer, a second throw of the first switch in communication with the second diplexer, and a third throw of the first switch in communication with the third diplexer, andwherein the second switch includes a first throw of the second switch in communication with the first diplexer, a second throw of the second switch in communication with the second diplexer, and a third throw of the second switch in communication with the third diplexer.

Abstract
Communication circuitry is disclosed that is capable of switching between three or more antennas while providing low harmonic interference during carrier aggregation. In one embodiment, a communication system includes a first switch with two poles and four throws, a second switch with two poles and four throws, and four diplexers associated with four antennas. In a second embodiment, the communication system includes a first switch with three poles and three throws, a second switch with three poles and three throws, and three diplexers associated with three antennas. In the second embodiment, the second switch may have a third pole associated with non-cellular signals such as GPS and WiFi, and one or more of the diplexers may be tunable, for example to efficiently pass 1.575 GHz for GPS signals.
