I would like to know more about the power detector circuit which
is included in the power amplifiers.
I am more interested in
power amplifiers for 802.11a/b/g.
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

I am designing a MMIC PA and
i want a power detector to be added on to the same chip.
i want some guidelines for designing a power detector.
articles on power detector would be very helpful.

Check the following Paper
Are you designing using GaAs or SiGe?
