ASML-5822
Schottky Assisted Low Power PIN Diode Limiter
Data Sheet
Description
The ASML-5822 is specifically 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.
Features
