Bandwidth of TEM Diode Limiters

To date diode limiters are either parametric frequent devices or simply diodes shunting a transmission line. The parametric limiters are narrow band because they must be made using cavities. Future techniques might improve their bandwidth but it is felt that in the limit their bandwidth would approach that of the techniques discussed here. The derivation of the bandwidth of a limiter consisting of diodes shunting a TEM transmission line is similar to the derivation of the bandwidth of a series diode switch. The attenuation a of an admittance G + jB shunting a transmission line of characteristic admittance Y/sub o/ is given by the equation.
