The invention provides a radio frequency framework and a mobile terminal. Signals within a first frequency band range, of low-frequency signals received by a master set antenna are transmitted to a receiving port of a transceiver via a first master set low-frequency port and a first master set low-frequency path, and the signals within a second frequency band range, of the received low-frequency signals are transmitted to a transceiving port of the transceiver via a second master set low-frequency port and a second master set low-frequency path. The signals within the first frequency band range, of low-frequency signals received by a sub-set antenna are transmitted to a transceiving port of the transceiver via a first sub-set low-frequency port and a first sub-set low-frequency path, and the signals within the second frequency band range, of the received low-frequency signals are transmitted to the receiving port of the transceiver via a second sub-set low-frequency port and a second sub-set low-frequency path. Due to such arrangement, the part of low-frequency resonance points are placed on the master set antenna, and the part of low-frequency resonance points are placed on the sub-set antenna, so that the two antennas have different resonance points, and thus the whole frequency band is covered.
Description
technical field [0001] The present application relates to a communication technology, in particular to a radio frequency architecture and a mobile terminal. Background technique [0002] In a North American operator, the LTE frequency band supports B2 / 4 / 5 / 12 / 14 / 66 / 71, and carrier aggregation (CarrierAggregation, CA) supports: B2+5, B2+12, B4+12, B2+4, B2 +71. [0003] For existing RF architectures, please refer to figure 1 , the main set antenna 11 is connected to the main set switch 12 , and the main set switch 12 is connected to the transceiver port of the transceiver 14 through the main set path 13 . The diversity antenna 15 is connected to a diversity switch 16 , and a frequency divider is integrated inside the diversity switch 16 , and the diversity switch 16 is connected to a receiving port of the transceiver 14 through a diversity path 17 . [0004] Since the main collector switch is integrated with a frequency divider, it can separate the intermediate frequency an...
