+5 to +30 dBm Limiter RLM-512-4WL+ 50 Broadband 50 to 512 MHz The Big Deal Very high CW input power, 4 W Very low limiting output power, 3 dBm typ. CASE STYLE: CK1246-1 Very fast response time, 2 nsec Product Overview The RLM-512-4WL+ protects against ESD and input power surges over a frequency range of 50 to 512 MHz, at power up to 4 W. Construction is on a micro strip low loss dielectric material and cased into a high volume, low cost package for cost efficiencies. Measuring 0.5 x 0.5 x 0.18 high, these tiny units provide excellent protection of low noise amplifiers in hostile environments where unwanted signals prevail, such as in manufacturing sites, train tunnels, etc. Key Features Feature Advantages Limiting abilities from 5 to +36 dBm RF Protects against strong undesired signals and prevents burn out of amplifiers and highly input sensitive components 3 dBm typ. output power Low power output prevents saturation of amplifiers following the limiter Frequency coverage 50 to 512 MHz Protection against many sources generating unwanted signals Response time 2 nsec Reacts almost instantaneously to limit unwanted high-level signals Minimal downtime after unwanted signals are removed, with very quick restoration of Recovery time 8 nsec standard operating levels Small surface-mount package Allows convenient placement in amplifiers incorporating this protective device Practical, low-cost solution to protect expensive amplifiers or other sensitive applica- Low cost tions from burning out Notes A.
