Description

Technical Field

[0001] This utility model relates to the field of communication equipment structural design technology, and in particular to an integrated airborne shortwave communication device. Background Technology

[0002] Existing airborne shortwave communication equipment mainly consists of transceivers and antenna tuners, with power amplifier modules and antenna tuners being independent components. These are all functional modules based on a frame design, arranged individually or in an array. The disadvantages of this type of structure are quite obvious. On the one hand, it is limited by the structural design, making it impossible to flexibly expand or shrink the structural size according to the functional modules; on the other hand, this type of chassis cannot simultaneously meet the dual requirements of efficient space utilization and heat dissipation performance.

[0003] As airborne shortwave communication equipment becomes increasingly functional and its integration level continues to rise, the heat flux density of the equipment is rising sharply, making heat dissipation design a crucial aspect of structural design. Furthermore, due to the unique nature of their installation platforms, airborne communication equipment operates in harsh mechanical environments; and to improve aircraft maneuverability, strict weight requirements are also imposed on the equipment. Therefore, integration, miniaturization, and lightweighting have become the development trends for airborne communication equipment.

[0004] To achieve high integration, efficient space utilization, and combined installation of multiple functional modules in airborne shortwave communication equipment, while also considering the system's heat dissipation design, electromagnetic shielding design, vibration reduction, and corrosion prevention requirements, it is urgent to design an airborne shortwave communication device that integrates a power amplifier module and an antenna tuner. This will adapt to the future trend of integrated communication systems and improve the equipment's adaptability to installation. Utility Model Content
