RLM-33+ Limiter 50 Broadband 30 to 3000 MHz The Big Deal Wide Frequency range 30 to 3000 MHz CASE STYLE: TT1224 Excellent limiting beyond +12 dBm input power Very quick recovery time, 10 nsec Low insertion loss, 0.23 dB Product Overview The RLM-33+ is packaged in a miniature size (0.25 X 0.3 in.) and protects against ESD and input power surges over a frequency range 30 to 3000 MHz. Construction is on a micro strip low loss dielectric material and cased into Mini-Circuits high volume, low cost R package for cost efficiencies. The RLM-33+ limiter provides 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 +12 to +30 dBm Protects against strong undesired signals and prevents burn out of amplifiers Frequency coverage 30 to 3000 MHz Protects against many different types of unwanted signals including ESD Surface mount package, miniature size Allows convenient placement in amplifiers incorporating this protective device Provides minimal degradation to amplifier performance, especially for low noise Low insertion loss and VSWR amplifiers where input loss is critical Low Cost A practical solution to incorporate into amplifier design with a minimal affect on cost Notes A.
