B, C is constant；A, the width with line before and after B is respectively transformer section, C are the length of transformer section.
The radian section is designed according to above-mentioned functional relation, impedance matching can be realized in wider frequency band, in turn
It realizes and opens up wide band function.
8-18GHz ultra wide band No. two power divider of the invention, is made of three ports in total.Micro strip is placed in cavity
Among, power-devided circuit is etched in micro strip surface, signal input port and two signal output ports be divided into through cavity wall and
The power-devided circuit on micro strip surface is connected, and isolation resistance is placed between two output ends of power-devided circuit.When work, input letter
Number two paths of signals of the constant amplitude with phase is divided into after power-devided circuit by signal input port feed-in, respectively by two signals
Output port output.
8-18GHz ultra wide band No. two power divider of the invention has compact-sized, bandwidth, isolation height, amplitude
The advantages that phase equalization is high solves the problems, such as that existing power divider is unable to satisfy the output of ultra wide band and requires.
Another aspect of the invention also provide it is a kind of include above-mentioned 8-18GHz ultra wide band No. two power divider solid-state
Transmitter.
Beneficial effects of the present invention are as follows:
8-18GHz ultra wide band No. two power divider provided by the invention, realizes the band of more than two octaves or more
