Latest Patents

One of Donoghue's latest patents is for a Radio Frequency (RF) coupler. This RF coupler, implementable as an integrated circuit, features a first transmission line with both a first and a second line portion. The first end of this transmission line is coupled to an input port for receiving an RF input signal, while the second end is connected to an output port for providing an RF output signal. Additionally, the RF coupler includes a second transmission line formed between the first and second line portions, allowing the magnetic field produced by the RF input signal to envelop the second transmission line. This design includes a coupled port for providing a coupled RF signal and a termination element to form an isolation port.

Another significant patent is the High Directivity Ultra-Compact Coupler. This coupler consists of a substrate and a stack of first and second dielectric layers extending over the top surface of the substrate. The first dielectric layer is made of a different dielectric material than the second layer. Two conductive lines extend over the stack of dielectric layers, formed in the same plane parallel to the substrate's surface. This innovative design enhances the performance and efficiency of RF couplers.
