RF/Microwave Limiters

RF/Microwave limiters are electronic devices used to protect sensitive radio frequency (RF) and microwave components from high power or high voltage signals. They are commonly used in RF and microwave communication systems, radar systems, and electronic warfare systems to prevent damage from unwanted signals or transient voltage spikes.

The basic function of a limiter is to pass a low power signal while attenuating any signal that exceeds a predetermined threshold. This is achieved using nonlinear circuits, which become highly resistive when the input power exceeds a certain level. The nonlinear circuitry can be implemented using various technologies, such as diodes, transistors, and ferrite devices.

RF/Microwave limiters have several advantages. They can protect sensitive electronic components from damage caused by high power signals, such as those generated by jamming, electromagnetic pulses, or lightning strikes. They can also reduce intermodulation distortion and improve the dynamic range of RF and microwave systems. Additionally, they can provide reliable and low-cost protection for electronic systems in harsh environments.

There are several types of RF/Microwave limiters available on the market, including PIN diode limiters, Schottky diode limiters, and ferrite limiters. The choice of limiter depends on the specific application requirements, such as the frequency range, power handling capability, and insertion loss. RF/Microwave limiters are an important component in many electronic systems and play a critical role in protecting sensitive components from damage.
