A specialised RF (Radio Frequency) power combining method called a Doherty combiner, sometimes referred to as a Doherty amplifier or Doherty power amplifier, is used to increase the efficiency and linearity of power amplifiers. It is frequently used to amplify signals with great efficiency and little distortion in wireless communication systems, such as cellular base stations.
The Doherty combiner is widely used in RF power amplification applications. It is especially useful in situations where strong linearity and high output power and efficiency are required.
A Doherty combiner’s main goal is to produce high efficiency and linearity by combining the outputs of two amplifiers, commonly known as the main and peaking amplifiers.
The main path and the peaking path are separated from the input signal to create the two pathways that make up the Doherty combiner. The peaking amplifier is only engaged when a greater output power is necessary since the main amplifier runs constantly and manages the majority of the input power.
The primary amplifier of the Doherty design runs in Class-AB mode, offering high linearity and efficiency at low to moderate output power levels. In a Class-C mode, which offers great efficiency but reduced linearity, the peaking amplifier runs.
The Global Doherty Combiner Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Xinger brand Doherty combiners are significantly smaller than printed Doherty combiners while maintaining performance that is at least as good. They are surface-mountable, low-impedance, perfect for handling high power, and provide outstanding wideband performance from 700 to 2700 MHz.
We provide Femto (20W), Pico (50W), and E-size (200W) Doherty combiners. Doherty combiners made by Xinger® feature a universal footprint that may be applied to any frequency bands. They may be used with TTM’s affordable 2-5dB couplers to make asymmetrical Doherty combiners with ease.
The Doherty power amplifier (DPA)’s bandwidth must be expanded if it is to work with future wireless communication systems. In order to provide an ultra-wideband DPA, a redesigned combiner combined with a complicated combining impedance is used in this research.
In the meanwhile, a thorough investigation of the suggested approach is conducted. It is shown that the suggested design technique can provide power amplifier (PA) designers additional flexibility when putting ultra-wideband DPAs into practice.
