We tried to connect a camera to two tx and we have a problem . It looks like that the signal coming from the camera isn't strong enough for drive to TX. Did somebody already deal with this problem?

Thanks evebody

Hehe
Exactly the same problem than this one.

We actually solved that problem at the ground station. The problem that we want to solve now is on the model airplane. We cannot install that kind of amplifier on the plane , too heavy too big. Any other ideas?.

Thanks

You could use one of Maxim's high speed op amps like the MAX477 as a buffer. With 70mA output current it should hold the load.
Or a MAX4202 buffer.
Have a look at their site, they have many good video muxes/amps/etc. There should be something that fits your needs.

The impedances are all wrong. Actually, Maxim makes some really good video distribution amplifiers which will solve the problem. Go to the MAXIM-IC site and look at the app-notes (yea, been there...done that). Hope this helps.

See attached for a Dual Video Buffer using a Maxim IC. You can get the chip as a free sample from their web site.
