Need help with a project

I need to design a wireless link for transmit audio (mono) over 2MHz carrier to a small distance (10 m). I was thinking to use infra red to do this, using FM modulation. Thoes anyone has a project like this ( Tx and Rx) , ou can anyone sugest a ic for this? I don't have any experience with pll design. Any help is welcome. Thanks.

Hi,

If you want to do it using IR, the 2 MHz carrier does not apply.

I think direct modulation of an IT diode at Tx and phototransistor at Rx should do it. I don't have schematics but I think you can or already have googled for them.

Regards,

Gam
