采用RFID(射频识别)芯片IA4420设计了一款主动式应答器,主要应用于矿井安全生产管理。其工作中心频率为905 MHz,数据通信的核心部分是印刷偶极子天线,从仿真结果来看:其相对带宽约为40%,增益约为4.236 dB,输入阻抗接近纯电阻 50 Ω,性能参数较好。 ...
给出一种实时互锁式无线抢答手柄的设计应用实例,使无线抢答器的死区时间由通常的40 ms锐减为40 μs。其基本思路是:在每只抢答手柄中增加一片射频接收模块和一个电子开关、配以相应的附属电路,使该电子开关受控于接收模块输出信号的有无,并决定手柄中的射频发射模块是否通电工作,从而实现各抢答手柄之间...
Radio frequency (RF) can be a complex subject to navigate, but it does not have to be. If you are just getting started with radios or maybe you cannot...
