An electronic device, comprising:

• at least one antenna configured to transmit and/or receive signals within a plurality of frequency bands;
• wireless communication circuitry configured to operate in the plurality of frequency bands;
• and
• an antenna switch module configured to pass signals between the antenna and the wireless communication circuitry, the antenna switch module including:
• a plurality of antenna switches configured to selectively operate in one of the plurality of frequency bands in response to a control signal, the plurality of antenna switches including:
• a first antenna switch with a first plurality of pins arranged in a first configuration, the first plurality of pins including a first plurality of signal pins, a first control pin, and a first input/output pin, the first control pin and the first input/output pin arranged on a first side of the first antenna switch,
• a second antenna switch, positioned in series with the first antenna switch, with a second plurality of pins arranged in a second configuration, the second configuration being a mirror image of the first configuration, the second plurality of pins including a second plurality of signal pins, a second control pin, and a second input/output pin, the second control pin and the second input/output pin arranged on a second side of the second antenna switch, the second antenna switch and the first antenna switch located adjacent to opposing sided of the antenna switch module, and
• a plurality of non-overlapping signal paths coupled to the first antenna switch and the second antenna switch without crossing, each signal path being associated with a respective one of the plurality of frequency bands, the at least one of the first or second control pin in each of the first or second antenna switch configured to receive the control signal, the first or second input/output pin in each of the first or second antenna switch configured to pass signals to or from the first or second antenna switch, and the first or second of the plurality of signal pins in each of the first or second antenna switch configured to be selectively coupled to the first or second input/output pin in response to the control signal, each of the first or second signal pin of the first or second plurality of signal pins associated with a respective one of the plurality of frequency bands being coupled to the signal path associated with the same frequency band, and each of the plurality of non-overlapping signal paths comprises a matching network configured to impedance match the first antenna switch with the second antenna switch.
