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?
