Abstract

The invention relates to a class F power amplifying circuit and a RF (radio frequency) power amplifier for 5G networks, and belongs to the field of wireless communication. The circuit comprises an input matching network, a DC bias circuit, a preamplifier circuit, a power stage amplifying circuit, and an output matching network. The current multiplexing technique is employed in the preamplifier circuit to increase the gain and stability of the power amplifier. A third-order resonant network is added to the output impedance matching network of the RF power amplifier to control the secondary andthird harmonics of the input signals, thereby improving the efficiency of the RF power amplifier. The two-stage structure achieves high gain and high efficiency of the power amplifier and improves thestability of the circuit.

Description

technical field [0001] The invention relates to a radio frequency power amplifier suitable for 5G networks, belonging to the field of wireless communication. Background technique [0002] With the rapid development of the mobile Internet and the evolution of new terminal forms, the demand for data services is showing an explosive growth trend. The existing 4G technology can no longer meet such a huge data service transmission demand. Therefore, the research and development of 5G technology has been neglected. on the agenda. However, as the next generation wireless mobile communication network, 5G needs to have the characteristics of low cost, low energy consumption, safety and reliability. In order to meet the needs of future 5G wireless communication networks, modern mobile communication terminals will also undergo major changes, especially in terms of their performance, which will require high-efficiency and energy-saving features. RF Power Amplifier (PA) exists at the e...
