Abstract
The invention relates to an electric bridge power splitter which belongs to the technical field of electronic communication and aims to solve the technical problems of large size, heavier weight, poor reliability, narrow frequency bandwidth and the like of the traditional electric bridge power splitter. The electric bridge power splitter comprises an electric bridge 3, a power splitter 4 and a power splitter 5. The power of an input signal which enters the electric bridge 3 by a port 1 is split by the electric bridge 3 so as to obtain signals with a phase difference of 90 DEG C; the signals are outputted into antenna ports 8 and 9; the power of an input signal which enters the electric bridge 3 by a difference port 2 is split by the electric bridge 3 to obtain signals with a phase difference of 90 DEG C; and the signals are outputted into antenna ports 6 and 7. The electric bridge power splitter is suitable for the fields of microwave communication, electronic equipment and the like.
Description
Technical field

The radar of pulse system forms and the difference beam network on the X-band of array antenna at present, mainly adopts waveguiding structure, and mainly there are the following problems for this class formation:
1. bulky;
2. weight is heavier;
3. poor reliability;
4. frequency band width.
Summary of the invention
The present invention is intended to solve bulky, the technical problems such as weight is heavier, poor reliability, frequency band width that exist in the existing electric bridge power splitter product, and a kind of volume is little, in light weight to provide, good reliability, wide frequency range, finished product high conformity, electric bridge power splitter that stability is high.
The objective of the invention is to be achieved through the following technical solutions.
Electric bridge power splitter of the present invention is made of electric bridge 3, power splitter 4 and power splitter 5, by entering the input signal of electric bridge 3 with port one, obtains the signal of phase phasic difference 90 degree after electric bridge 3 is divided equally as signal power, and it is outputed to antenna port 8 and 9; Enter the input signal of electric bridge 3 by difference port 2, after electric bridge 3 is divided equally as signal power, obtain the signal of phase phasic difference 90 degree, it is outputed to antenna port 6 and 7.
