asml-5829 schottky assisted low power pin diode limiter data sheet description the asml-5829 is specifcally designed for low power limiter applications, where it can be used to protect the receiver system from being damaged by large input signals, and allow the receiver system to function normally with the absence of large signal. the schottky enhanced limiter will have a lower limiting threshold compared to the more conventional self-biased pin limiter. the pin diode is placed at the input, to protect the schottky from high rf power levels. pin connections, package marking & orientation, sot-323 notes: gb = device code ? = month code indicates the month of manufacture features ? low power limiter with unique combination of pin and schottky diode ? low limiting threshold power (op1db: 6.05 dbm @900mhz) ? semi integrated solution in surface mount sot-323 package C increase fexibility C save board space C reduce cost ? pin diode features: C low capacitance C low resistance at low current C low failure in time (fit) rate [1] ? schottky diode features: C low turn-on voltage (as low as 0.34 v at 1 ma) C low fit (failure in time) rate [1] note: 1. for more information see the surface mount pin reliability data sheet. gb? pin diode schottky diode
