Neep help to design a Coupling circuit for Power line communication

[umair121]

Hi

I need help designing a coupling circuit for Power Line communication for home automation. I will be using a powerlines FSK modem in my final project but initially i want to test my coupling circuit.

i am using this coupling circuit


with a basic function generator and an oscilloscope but i am getting a very attenuated output at the receiver. can anyone help me with this problem or suggest me some other simple coupling circuit that can work with frequencies up to 200khz

Thanks

you can use TDA5051 for communication.

Yes TDA5051 is an option but my confusion lies with coupling circuit? can anyone help me with the coupling circuit to be used ?

i will be using
CY8CPLC10 fsk modem for my project from Cypress.

any schematic for a coupling circuit along with the ratings of the components use will be really helpful
