Description
The Filtronic LML 221 Limiter is a MIN (Mott) diode limiter featuring low insertion loss, excellent pulse recovery time, and low spike leakage
energy. The diode structure features a very stable Pt / Ti / Au Schottky contact, with low resistance ohmic AuGe / Ni / Au ohmic contacts.
The MIN structure allows for a large diode area for improved maximum burn-out power levels while retaining wide-bandwidth performance.
The MIN diodes do not generate minority carriers, thereby offering superior pulse recovery and spike leakage performance as compared to
standard PIN limiters.
