SKL-0631831643-SFSF-S1-M is a broadband RF limiter that utilizes a high-performance GaAs Schottky diode MMIC chip that can limit input power up to +43 dBm with a leakage of +16 dBm. The limiter’s function is to prevent damage to sensitive components, such as mixers, low noise amplifiers, switches, etc. from excessive input power. The input and output ports are SMA connectors. Other RF connector types are offered under different model numbers.
