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.

like to know more about the power detector circuit which is included
in the power amplifiers.
I am more interested in power amplifiers
Can someone suggest some articles on designing the
power detector for the same ?

I would assume that some type of directional coupler is used.
You do not want the detector to affect impedance or S21 params. So using
a driectional coupler would satisfy those requirements. At the pooper
end of the coupler I would think a simple detector diode with temp comp.
But you did mention 802, and I am not versed in the technology so maybe
I should be quiet

I am designing a MMIC PA and i want
a power detector to be added on to the same chip.
Hence i want some
guidelines for designing a power detector.
Any related articles on
power detector would be very helpful.
with best regards,

you designing using GaAs or SiGe?
