Abstract

The invention provides a high-power lumped element power divider with -45-degree phase delay. The high-power lumped element power divider comprises an input port and two output ports, an matching inductor one end of which is connected to the input port, and the other end is grounded; the transfer capacitors which are respectively connected between the input port and the two output ports; and an isolation unit which is connected between the two output ports, and comprises an isolation inductor and an isolation resistor, wherein the isolation inductor and the isolation resistor are connected inparallel between the two output ports, or the isolation inductor and the isolation resistor are connected in series between the two output ports. According to the invention, the problem that the classic Wilkinson power divider is not suitable for high-power signal transmission is solved.

Description

technical field [0001] The invention relates to the field of radio frequency / microwave technology, in particular to a high-power lumped element power divider with a phase delay of -45°. Background technique [0002] A power divider (referred to as a power divider) is one of the basic components of a microwave circuit. It has a multi-port microwave network that decomposes the input signal power into several isolated equal or unequal power signals, or vice versa. Signals of equal or unequal power are combined into one way, so it is sometimes called a power divider / combiner. Power splitters are widely used in circuits and systems such as power amplification and synthesis, signal testing, quadrature mixing demodulation, and antenna beamforming, and their performance will affect the communication quality of the entire circuit or system. [0003] Among the microstrip power splitters, the Wilkinson (Wilkinson) power splitter has good characteristics due to its own structural chara...
