+10 to +37 dBm Limiter RLM-43-5W+ 50 Broadband 20 to 4000 MHz CASE STYLE: TT1224 The Big Deal Broadband, 20 MHz to 4 GHz Low output power leakage, +12 dBm Excellent limiting range,+10 to +37 dBm 0.3 dB output / 1 dB i nput Product Overview Mini-Circuits RLM-43-5W+ is a passive PIN diode RF limiter ideal for protecting sensitive receiver circuitry from high-power signals, while allowing low-powered signals to be received. Providing limiting range from +10 to +37 dBm and +12 dBm typical output power, the RLM-43-5W+ is ideal for many situations where unwanted signals prevail such as manufacturing sites, train tunnels, radar transceivers and more. The limiter is housed in a durable, surface mount plastic enclosure measuring 0.25 x 0.31 x 0.16, accommodating tight PCB layouts. Key Features Feature Advantages Wideband operation, from 20 to 4000 Ideal for a variety of applications where there is a need to protect sensitive receiver circuitry from MHz unwanted signals as well as control ESD and power surges on the network. Excellent limiting range from Prevents undesired signals from passing through the network and damaging sensitive electronic +10 to +37dBm components. Low delta output per 1 dB delta input maintains signal stability in the presence of volatile input 0.3 dB output / 1 dB input signal conditions. Minimal downtime after unwanted signals are removed with very quick restoration of standard Rapid recovery, 33ns operating levels. Low loss insertion, 0.36 dB Preserves the strength of low-power signals in the receive path. Low output power prevents saturation of receiver circuitry and provides extra protection for low-output power loss, +12 dBm sensitive components. Notes A.
