Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: what is limiter and its application

Recently my work involves so-called limiter. I am quite confused of its characteristics and application in the digital communication system(QPSK, etc). Can any expert give some hints?

There are two components you may be referring to.
One is a high power protection device using PIN diodes. The purpose is to clamp a high power signal to avoid damaging sensitive components on the front end of the receiver.
The other is a limiting amplifier, also referred to as a limiter. This is an amplifier operating in saturation, providing a fixed output level over a wide range of iput power.
