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
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. pallavi_d Post subject: Power Detector in Power Amplifiers Posted: Thu Oct 06, 2005 4:27 am Captain Joined: Thu Oct 06, 2005 3:45 am Posts: 7 Location: India Hi all, 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 ? Thanks Pallavi Top attenuator Post subject: Posted: Thu Oct 06, 2005 10:05 pm Captain Joined: Mon Sep 26, 2005 7:29 pm Posts: 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: Power Detector in Power AmplifiersPosted: Fri Oct 07, 2005 1:26 am Captain Joined: Thu Oct 06, 2005 3:45 am Posts: 7 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 Top Arul Post subject: On Chip RF Power DetectorPosted: Sun Oct 16, 2005 5:57 pm Hi, Check the following Paper http://www.ireap.umd.edu/MURI-2001/Revi ... gailis.pdf Are you designing using GaAs or SiGe?
