Is it possible to make a WLAN amplifier to send/receive on t

[Ole]

Hi

I'm thinking to make a WLAN amplifier that amplifies the signal before
it sends it on.

antenna|->-amplifier---->>---|antenna
|---<<----amplifier-<-|

But I can't think of a way to make it work with one antenna, the
amplifier will amplify booth signals, the signal from the antenna and
the one from the amplifier, in simpler words, it will oscillate.

Is there a way to make it work?

The signal it shall amplify is around 2.4GHz

Regards
Ole

Congratulations Ole,

I think you have just reinvented the oscillator.

Google Simplex, Duplex, Isolator, circulator, duplexor

If the transmit frequency and the recieve frequency
are the same ("simplex") is if you have lots of
physical and electrical isolation between antennas.

If you know when one end is transmitting, (push-to-talk)
you can switch the amplifer so that it only works
one direction at a time.

If you transmit on one frequency, and recieve
on a different frequency ("full-duplex"), you can
use selective filters (duplexer) to provide the
necessary isolation.
