一种使用FPGA实现的微波开关阵列适配器模块OA

In order to automatically connect the microwave communication link between the calling party and the called party in the low orbit satellite communication network,we build a specialized microwave PBX to achieve this function,and the microwave switch array adapter is a key component of the equipment.The adapter modular is designed on the PXI bus.Its system controller accesses the local I/O adapter following the ISA bus specification through the PCI bus bridge,thereby realizing the on/off control and telemetry status detection operation of the microwave switches.The PCI bus bridge is implemented using low-cost PCI9052,while the local ISA bus logic signal generation and I/O adapter circuit are programmed using a domestically produced FPGA circuit.After the modular development is completed,the main functions and performance are tested in the laboratory,satisfying the performance targets.
