Seven-channel frequency conversion module applying ADF4360-7 integer frequency division

Abstract

The invention provides a seven-channel frequency conversion module applying ADF4360-7 integer frequency division. The module comprises a high-precision temperature compensation crystal oscillator, anamplifier, a first power divider, a second power divider and a local oscillator unit. The output end of the high-precision temperature compensation crystal oscillator is connected with the input end of the amplifier. The output end of the amplifier is connected with the input end of the first power divider, the output end of the first power divider is respectively connected with the second power divider and the input ends of the three local oscillator units, and the output end of the second power divider is connected with the input ends of the four local oscillator units. According to the seven-channel frequency conversion module, seven-channel design can be completed by only making one board, the requirements of all channels are met by changing individual devices, and the cost is reduced.Meanwhile, the PLL design of integer frequency division is adopted, the isolation between channels can be improved, and the purposes of high phase discrimination frequency and low phase noise are achieved.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a seven-channel frequency conversion module applying ADF4360-7 integer frequency division. Background technique [0002] The seven-channel frequency conversion module is mainly used in the frequency conversion (modulation and demodulation) part of the wireless communication system, especially the multi-channel frequency conversion. In the seven-channel frequency conversion module, it is required that the signal frequencies of each channel are different and the channel spacing is relatively large, but this requirement cannot be met in the prior art. Contents of the invention [0003] To solve the above technical problems, the invention provides a seven-channel frequency conversion module using ADF4360-7 integer frequency division. [0004] In order to solve the problems of the technologies described above, the technical solution adopted by the present invention is: [0005] A sev...
