Both RF filters and limiters are integral components in RF circuits, contributing to signal quality & system performance. RF filters are devices that selectively allow or block specific frequencies within an RF signal. They play a critical role in shaping the frequency response of a system, ensuring that only desired frequencies pass through while attenuating unwanted frequencies. Filters are used to remove interference, improve signal quality, and comply with regulatory standards. Common types of RF filters include low-pass, high-pass, band-pass, and band-stop filters, each serving specific filtering requirements in RF applications. RF limiters are devices that protect sensitive electronic components from high-power or high-amplitude signals. They limit the amplitude of incoming RF signals to prevent damage to receivers or other components that may be sensitive to excessive power levels. RF limiters are commonly used in applications where there is a risk of exposure to high-power signals, such as in radar systems, communication receivers, and electronic warfare systems. They help maintain the integrity and reliability of RF systems by preventing signal overload.
