Abstract
Integrated Doherty power amplifiers are provided herein. In certain implementations, a Doherty power amplifier includes a carrier amplification stage that generates a carrier signal, a peaking amplification stage that generates a peaking signal, and an antenna structure that combines the carrier signal and the peaking signal. The antenna structure radiates a transmit wave in which the carrier signal and the peaking signal are combined with a phase shift.
Claims20
A radio frequency antenna structure that combines and phase shifts a carrier signal and a peaking signal, the antenna structure including a patch antenna element and an impedance transformer having a first metal region and a second metal region of different widths, the second metal region connecting the first metal region to the patch antenna element.
A mobile device comprising:
- a transceiver configured to generate a radio frequency input signal;
- and
- an antenna structure that combines and phase shifts a carrier signal and a peaking signal, the antenna structure including an impedance transformer having a first metal region and a second metal region of different widths, the second metal region connecting the first metal region to a patch antenna element.
