Embodiment Construction

[0027] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0028] Such as figure 2 As shown, the present invention discloses a broadband four-power divider, including: port 1, port 2, port 3, port 4, port 5, a first transformer, a second transformer, a third transformer, a first isolation resistor, a second Two isolation resistors, an optional first compensation capacitor, and an optional second compensation capacitor.

[0029] The primary coil of the first transformer is connected to the input port, that is, port 1, and the two ends of the secondary coil are respectively connected to one end of the primary coil of the second transformer and one end of the primary coil of the third transformer; The radio frequency signal is converted into two signals with opposite phase and equal amplitude;

[0030] The first transformer is essentially a 1:1 balanced unbalanced converter (BULUN), which divides the radi...

Abstract

The invention discloses a broadband four-power divider, which includes a first transformer, a second transformer, and a third transformer; the primary coil of the first transformer is connected to an input port, and the two ends of the secondary coil are respectively connected to the primary coil of the second transformer One end of the primary coil of the third transformer and one end of the third transformer; the first transformer is used to convert the input radio frequency signal into two signals with opposite phases and equal amplitudes; the second transformer and the third transformer are respectively used It is used to convert the input signal into two output signals, and finally realizes four power divisions of the input signal; compared with the existing power divider, the structure is simple and the loss is low.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a broadband four-power divider. Background technique [0002] The power divider / combiner is a power distribution and synthesis component in the field of radio frequency and microwave technology, and is widely used in broadcasting and television systems, communication systems, radar systems and other fields. Commonly used power divider technologies mainly include power divider technology based on ferrite core transformer, power divider technology based on transmission line (microstrip power divider, coaxial line power divider, waveguide power divider, etc.), and There are LC splitter technologies for narrower frequency bands or resistive splitter technologies for larger losses. In some broadband applications, the working frequency band often includes HF and UHF and higher frequency bands at the same time. Due to the long wavelength included, it is more suitable to use th...
