RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Power Detector in Power Amplifiers - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including 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?
