摘要： A wireless communication includes multiple transceivers that may be utilized for wireless communication over multiple frequency ranges. One of the transceivers is communicatively coupled to antennas that may be utilized to transmit or receive wireless signals having frequencies in different portions of one of the frequency ranges.

摘要： Electronic devices may be provided with wireless circuitry having an antenna, a primary receiver, and a secondary receiver. The primary receiver may be coupled to the antenna over a first signal path having a low noise amplifier. An input of the primary receiver may be coupled to the first signal path and an input of the secondary receiver may be coupled to a node on the first signal path over a second signal path. The primary receiver may consume more power and exhibit more linearity than the secondary receiver. The secondary receiver may wake while the primary receiver is asleep and may wake the primary receiver when paging signals are received. If desired, the wireless circuitry may be switched between a single-receiver mode and a receiver diversity mode based on wireless performance metric data gathered by the primary receiver and/or the secondary receiver.
