Problems solved by technology
The disadvantage is that if there are, for example, signals in eight frequency bands in the application scenario, the design scheme must design corresponding eight-channel signal receiving links, which increases the difficulty of the design scheme. It is necessary to ensure that no mutual interference occurs on each link and To ensure the performance consistency of each link, new investment and requirements will be added to the design cost

A multi-band signal reception selection control circuit includes: an antenna for receiving external signals; a broadband power divider coupled to the antenna, used to divide the signal received by the antenna into at least two signals with the same power as each other; The at least two RX receiving signal channels of the power divider are used to correspondingly receive the at least two signals with the same power through the input terminal for signal processing; the broadband combiner coupled to the RX receiving signal channel is used for Combining and outputting the signals after branching processing; and a microprocessor control circuit, which is coupled to the switch provided on each RX receiving signal path through the RX channel bus, and controls the communication of the switch according to an enabling signal. to perform band selection.
Description
【Technical field】 [0001] The present invention is mainly aimed at the technology that communication equipment needs to receive signals of multiple frequency bands and select one or more applicable frequency bands in a communication system, especially in the coexistence mode of multiple frequency bands, providing a receiving device can realize multiple A circuit and method for selecting and receiving signal frequency bands. 【Background technique】 [0002] In the usage scenario of a general communication system, the link used as a receiving signal is basically designed as a single independent system, which is not suitable for receiving signals with multiple frequency bands and different bandwidths. A receiving system suitable for multiple frequency bands is usually designed with receiving chains for multiple frequency bands. Such a system design scheme is generally used in a conventional receiver system, so this type of design scheme reflects the disadvantages of relatively e...
