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.
Post subject: output power loss due to VSWR Posted: Sun Jan

In my Tx chain i have at the end
a PA (power amplifier) with output VSWR of 2:1
then I have a losses
due to RF cables of 1dB, and at the end of the chain there is antenna
with VSWR of also 2:1
my question is if the output power of the amplifier
is 50dBm, what will be the output power from the antenna.(assume the
gain of the antenna is 1dB) caused by the impedance mismatch.

It depends on the exact impedances and length of the transmission line.
The details matter.
