Where can I find bidirectional Rf amplifier? 1

[pucca]

Hi I need to find a bidirectional rf amp, surface mounted at 2.4 GHz. I could use switches and two rf amps but I would rather not to(I have one rx/tx path).I haven't found something though I have searched the net
Thanks in advanced!

So, use switches and ONE RF amp. Presumably, you're not trying to transmit and receive at the same time with the same amplifier.

There is no such thing as a bidirectional amplifier, RF or not. The closest you can get is a transceiver, which is two RF amplifiers with switches.

Bidirectional amplifiers can be used provided there is a frequency band difference. For example, pole-mounted Cable TV amplifier are bi-directional since they carry the back-channel signals (PPV orders, Internet uplink, etc.) from the customers back to the head-end.

Bidirectional amplifiers in the same frequency range are called oscillators.

Hiya-

As VE1BLL mentioned there has to be a frequency difference. It need not be in a different band. In the Ham Radio world at 2 meters the split difference is 600KHz. At 2.4 G I am assuming that the resonators would be rather small. Of course, good isolation is required. Don't think that the Hams are setting up 2.4 GHz repeaters but might be a worthwhile read of their microwave literature.

Cheers,

Rich S.

Very well put! VE1BLL. PLS.

2m Ham repeaters don't normally use 'bidirectional amplifiers'. They'll have a receiver, a transmitter, and a bank of tuned cavity filters occupying roughly half a cubic meter.

Ok I got it..there isn't such amp....thanks alot again for the help guys
