Title: NON-INTER-BAND UPLINK CARRIER AGGREGATION CIRCUIT AND DEVICE
Abstract:
Disclosed is a non-inter-band uplink carrier aggregation (ULCA) circuit comprises: a combiner receiving radio-frequency signals in various frequency bands; a radio frequency switch; and a mobile industry processor interface (MIPI). The radio frequency switch is controlled by control information inputted from the MIPI. The MIPI receives a control signal determined according to whether a terminal currently has access to an ULCA operation mode and controls the radio frequency switch. An input terminal of the radio frequency switch is connected to an input terminal of the combiner, and an output terminal of the radio frequency switch is connected to an output terminal of the combiner. Also disclosed is a non-inter-band ULCA device.
