Limiters are necessary in situations in which a transmitter delivers signals of peak power on the order of kilowatts or megawatts to an antenna that also connects to the receiver. Receivers, however, ...

This file type includes high-resolution graphics and schematics when applicable. Measuring the signals from extremely high-impedance sensors is a difficult task. Such sensors can have output ...

A Zener diode is the simplest known type of voltage limiter (Figure 1) As soon as the voltage exceeds the rated voltage of the Zener diode, a current can flow through the diode to limit the voltage.

Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems. However, designers still must deal with the upper-frequency limit problem ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...
