With the rapid development of radar electronic technology, the requirements for miniaturization, lightweight, high integration and high reliability of the equipment are constantly improving. RF power division network plays the role of interconnecting the different channels of phased array radar and the discrete modules in the whole telecommunication link, and its integration degree is one of the keys to realize miniaturization and high integration degree of radar equipment. In the traditional electronic system equipment, The signal transmission between each functional module or unit is mainly connected by cables.         Due to the complexity of radar system, the number of signal channels, and the high-frequency transmission requirements, the high-frequency signal transmission between each functional module almost relies on rigid cables and high-frequency connectors, making its structure volume large, Low integration. The RF feed network based on the vertical interconnection technology of buttons can greatly reduce the number of interconnection cables and connectors, and realize the three-dimensional vertical interconnection. Because it has the advantages of no welding, repeatable disassembly and repair, it can also ensure the good connection and high reliability in the vibration environment, In recent years, it has been widely used in aerospace and military fields
       Based on the elastic interconnection technology of the button, a 1:16 X-band power division network is designed, which can greatly reduce the number of interconnection cables and connectors, realize three-dimensional vertical interconnection, and has the advantages of no welding, repeated disassembly and repair. The Wilkinson power divider, the vertical transition of metallized holes and the vertical interconnection of buttons are modeled and simulated. The test fixture of the button to button connector is designed and manufactured. The test results show that the amplitude consistency among the standing wave, insertion loss and taps is tested and verified. The test results show that the standing wave is less than 1.4 and the insertion loss is less than 16.5db in the frequency band of 8-12ghz.
