GPS分路放大器的设计

Design of GPS Splitter Amplifier

传统的机载GPS天线与飞行员手持接收机之间存在有线连接,会影响飞行员应急逃生。为解决这个问题,在新的GPS座舱接收系统中加入GPS分路放大器和GPS无源发射天线组成的GPS转发装置,将GPS信号转发给GPS手持机。它是一个无线转发接收系统,当危险状况出现时,有利于飞行员应急逃生。采用成熟的传输线理论和有源电路分析方法对其中的GPS分路放大器进行理论分析和仿真设计,电路实测结果验证了设计方法的可行性和设计参数的正确性。

Because of the cable connection between the traditional airborne GPS antenna and the pilot handset receiver, the pilot emergency evacuation may be affected. To solve this problem, the new GPS cockpit receiving system adds a GPS forwarding device, which consists of the GPS splitter amplifier and the GPS passive transmitting antenna. The GPS signal is transmitted to the GPS handset receiver in the wireless forwarded receiving system. When the dangerous case occurs, the system could help the pilots escape quickly. The GPS splitter amplifier is analyzed and simulated based on the transmission line theory and active circuit analysis method. The circuit measurement results verify the feasibility of the design method and the accuracy of the design parameters.
