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: sending 20MHZ rf signal

I need to buy a chip that is able to send 20MHz sin wave massage and a receiver chip that
is able to receive that 20 MHz sin wave.
It can use carrier or not, but the idea is for the 20
MHz sin wave to be transmit within 15 m.
Can you pls help on how I can get the chip, I look
everywhere, they only transmit low frequency signal (KHz), or if I need to build one, what the
gain of the amplifier should be?
