摘要： An integrated circuit (IC) includes a receiver module, a transmitter module, an inbound digital module, and a local oscillation generation module. The receiver module is operable to convert an inbound high frequency signal into a down converted inbound signal based on a receive local oscillation independently of a protocol of the inbound high frequency signal. The inbound digital module is coupled to compensate the down converted inbound signal in accordance with a selected one of the first plurality of wireless communication protocols. The transmitter module is operable to convert a first outbound signal into a first up converted signal based on a transmit local oscillation when a first one of the first plurality of wireless communication protocols is active and to convert a second outbound signal into a second up converted signal based on the transmit local oscillation when a second one of the first plurality of wireless communication protocols is active.

摘要： A high frequency (HF) communication device includes an antenna structure, an integrated circuit (IC), and an off-chip duplexer. The IC includes a receiver section and a transmitter section. The receiver section is operable in a receive portion of a first frequency band to support multiple communication protocols and converts a filtered inbound HF signal into a down converted inbound signal in accordance with the multiple communication protocols. The transmitter section is operable in a transmit portion of the first frequency band to support the multiple communication protocols, converts an outbound signal into a first up converted signal when a first one of the multiple communication protocols is active, and converts the outbound signal into a second up converted signal when a second one of the multiple communication protocols is active. The off-chip multiple protocol duplexer is coupled to filter the inbound HF signal to produce the filtered inbound HF signal and to filter the second up converted signal to produce the outbound HF signal when the second one of the multiple communication protocols is active.

摘要： An adjustable mixer is disclosed that is capable of operating in different modes in order to satisfy the mixing requirement of multiple radio access technologies (RATs). The adjustable mixer includes a LO signal generating portion and a mixing portion. Depending on the mixing requirements of the RAT, the adjustable mixer can operate in any one of multiple modes, each mode having a specific configuration for the LO signal generating portion and the mixing portion. The LO signal generating portion generates a LO signal having a particular duty cycle, depending on the selected mode, for use by the mixing portion. The mixing portion has an adjustable circuit configuration that can be dynamically reconfigured based on the selected mode, and which allows the mixing portion to successfully mix received signals using the corresponding LO signals generated by the LO signal generating portion.
