I'm planning to have these 2 amps and biasing ICs on my design. I need 60 dBc or better isolation between the amplifiers.

 

Are there any VDD biasing designs or parts that can achieve that?

I'm currently using Murata LQP series wirewound inductors as output chokes, but I can't get 60 dBc isolation between the amps.

 

Please help. Thanks.
