Abstract
An RF coupler implementable as an integrated circuit includes a first transmission line having a first line portion and a second line portion. A first end of the first transmission line is coupled to an input port for receiving an RF input signal. A second end of the first transmission line is coupled to an output port for providing an RF output signal. The RF coupler further includes a second transmission line formed between the first line portion and the second line portion such that magnetic field produced due to the RF input signal in the first line portion and the second line portion envelops the second transmission line. A first end of the second transmission line is configured as a coupled port for providing a coupled RF signal, and a second end of the second transmission line is coupled to a termination element to form an isolation port.
