ACLM-4769F Pin Diode Low Leakage Limiter Data Sheet Revision Date: 12/22/2015 The most important thing we build is trust DESCRIPTION: Feedback limiters are designed to have lower threshold and leakage levels than those of conventional limiters in order to protect more sensitive components. They incorporate input PIN diode limiters which are driven by one or more schottky detector diodes. Most circuits include DC blocks, which are required for proper operation. In some very low frequency models, it is not possible to include DC blocks. The application must be such that no low impedance DC path from the center conductor to ground exists outside the unit. The limiter threshold (1dB compression) is typically +5dBm. Feedback limiters will also handle peak power levels above 100W (1usec pulse width, 0.001 duty cycle, and 1kHz repetition rate). Peak leakages are higher than CW leakages as they are with conventional limiters. This becomes exaggerated at frequencies below 2GHz.
