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
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

can some one explain me this circute,and why Rs>RL?

is called L-Pad attenuator, and is used to match between 2 impedance
levels. The ratio doesn't have to be necessarily RL>RS, it can be
also RS>RL, all depends on the application. This attenuator is basically
derived from the T attenuator (with one of the series resistors is reduced
to value of 0-ohm). This attenuator is designed to have minimum attenuation
You can calculate the resistor values of R1, R2 according
to the following formulas:
