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 ? Thanks Pallavi Top

13 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 Top pallavi_d Post subject:

Location: India Hello , 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, Pallavi
