Background
With the continuous development of technology in the communication field, especially the high-speed development of personal mobile communication, the low-end frequency of the radio spectrum is saturated, and even if the capacity of a communication system is enlarged by adopting Gaussian filter minimum shift keying (GMSK) modulation or various multiple access technologies, the utilization rate of the frequency spectrum is improved, so that the requirement of future communication development cannot be met. Therefore, the field of wireless communication is currently developing new spectrum resources towards high-speed, broadband microwave high-end. Millimeter waves have wide application prospects in short-distance communication because of the short wavelength and wide frequency band, and can effectively solve a plurality of problems faced by high-speed broadband wireless access.
In the prior art radio communication radio frequency system, the channel spacing of the radio frequency T/R module is narrower as the frequency is higher, and the ultra-small spacing thereof in the millimeter wave frequency band leads to that the traditional brick type T/R module must be prolonged from the height direction of the whole module structure when the processing structure in the signal transmission channel is arranged, but the method is not applicable to some systems with limited requirements on the height of the whole T/R module at all.
On the other hand, because the T/R module under the millimeter wave frequency band often has a high-density channel spacing, the T/R chips are densely distributed in the T/R module, and the traditional brick structure can cause the back-to-back placement of each T/R chip, and effective heat dissipation measures cannot be adopted, so that the communication system applying the T/R module often has very low power, and cannot meet the development requirements of the current high-power high-density phased array antenna.
Therefore, the conventional millimeter wave frequency band T/R module in the prior art cannot be applied to a radio frequency system with a limitation on the height of the whole module, and the technical problem of low system power caused by the fact that effective heat dissipation measures cannot be implemented is solved.
