US 2013/0157717 A1 · Wireless communications circuitry with a triplexer for separating radio-frequency signals in adjacent frequency bands

Abstract

A wireless electronic device may be used to communicate using multiple wireless standards in adjacent frequency bands. The wireless standards may include Wi-Fi® and cellular standards such as Long Term Evolution (LTE). The wireless electronic device may be provided with wireless communications circuitry that handles Wi-Fi® and cellular signals in adjacent frequency bands such as the Wi-Fi® 2.4 GHz frequency band and LTE bands 38 and 40. The wireless communications circuitry may include a triplexer interposed between transceiver circuitry and an antenna. The triplexer may be used to handle radio-frequency signals in adjacent frequency bands by separating the radio-frequency signals into signals associated with each frequency band. The triplexer may include filters that each pass signals in a respective one of the frequency bands between the transceiver circuitry and the antenna.
