2026 Top 10 RF Limiter Manufacturers in China - Blog

Introduction to RF Limiter

RF (Radio Frequency) limiters are crucial components in RF and microwave systems. Their primary function is to protect sensitive RF components, such as low - noise amplifiers (LNAs), mixers, and receivers, from high - power RF signals. When the input RF signal power exceeds a certain threshold, the RF limiter starts to limit the output power, ensuring that the subsequent components are not damaged by excessive power. RF limiters are widely used in various fields, including wireless communication, radar systems, satellite communication, and electronic warfare.
