Hi,

Pl advise any circuit or specific IC for Voice multiplexing.
I have 4 channels of voice signal, each channel has PTT+, PTT-, Tx+, Tx-, RX+ and RX-.
I need to switch between 4 channels to one output channel which will be connected to HF Radio.
Output impedance will be 600Ω.

Please help me with the circuit.

Thanks in advance.

regards,
Surendra
