Wideband power combiners and splitters are provided herein. In certain embodiments, a power combiner/splitter is implemented with a first coil connecting a first port and a second port, and a second coil connecting a third port and a fourth port. The first coil and the second coil are inductively coupled to one another. For example, the first coil and the second coil can be formed using adjacent conductive layers of a semiconductor chip, an integrated passive device, or a laminate. The power combiner/splitter further includes a fifth port tapping a center of the first coil and a sixth port tapping a center of the second coil. The fifth port and the sixth port serve to connect capacitors and/or other impedance to the center of the coils to thereby provide wideband operation.
A power combiner/splitter comprising:
A radio frequency system for combining signals, the radio frequency system comprising:
A radio frequency system for splitting signals comprising:
The radio frequency system 14 wherein the power splitter further includes a first capacitor connected between the first port and the third port, and a second capacitor connected between the second port and the fourth port.
The radio frequency system 15 wherein the power splitter further includes a third capacitor connected between the fifth port and a reference voltage, and a fourth capacitor connected between the sixth port and the reference voltage.
The radio frequency system 14 wherein the first conductive coil and the second conductive coil are interleaved.
The radio frequency system 14 wherein the first port and the third port are directly adjacent to one another with no intervening ports, and the second port and the fourth port are directly adjacent to one another with no intervening ports.
The radio frequency system 14 wherein the fifth port is directly adjacent to the third port with no intervening ports, and the sixth port is directly adjacent to the fourth port with no intervening ports.
The radio frequency system 14 wherein the first radio frequency circuit is a peaking amplification stage of a Doherty amplifier, and the second radio frequency circuit is a carrier amplification stage of a Doherty amplifier.
