Systems and methods for antenna switches in an electronic device

摘要

Systems and methods are provided for an antenna switch module (300) for an electronic device (302) including wireless communication circuitry (308) and an antenna (304) configured to transmit and receive signals over a plurality of frequency bands. The antenna switch module may include a plurality of antenna switches (310, 312) positioned in series and configured to pass signals between the antenna and wireless communication circuitry and to selectively operate in one of the bands. The first antenna switch (310) may include a plurality of pins (314) arranged in a first configuration, and the second antenna switch (312) may include a plurality of pins (316) arranged in a second configuration that is a mirror image of the first configuration. The antenna switch module may further include a plurality of non-overlapping signal paths (318) configured to selectively deliver signals between the antenna switches, each signal path being associated with a respective band.
