Specific embodiments
Fig. 1 and 2 describes specific embodiment of the invention scheme.Shown in Fig. 1 and 2, the present invention includes input socket (1), accessory power outlet (2), cavity (3) microstrip line (4) and isolation resistance (5) and dielectric-slab (6).
Time the input/output port of power splitter connects matched impedance, there is well isolation mutually without the need to connecing build-out resistor output port.But the circuit of reality generally needs isolation resistance due to process deviation etc.
In order to reach the frequency band of described power splitter, need to carry out more piece quarter-wave impedance transformation, first determine that the frequency of described power splitter is 1.5, frequency and peak frequency/minimum frequency, in conjunction with frequency, determine that by tabling look-up the joint number of 1/4 wave microstrip line is 2 rank, according to impedance matching principle, every one-level 1/4 wavelength line is mated, and then the characteristic impedance value determining every one-level 1/4 wave microstrip line is 1.667 and 1.1998, the present invention adopts Arlon DiClad880 microstrip substrate, the dielectric constant er of medium substrate is 2.2, substrate thickness H is 0.508mm, copper thickness T is 0.037mm, by the dielectric constant of substrate, thickness, the width that ADS software in conjunction with Aglient company calculates each section of microstrip line is respectively 0.614623mm and 1.133mm, the length of microstrip line is then 1/4 wavelength of centre frequency 2250MHz, be 25.0761mm and 24.6192mm, the last isolation resistance according to the separation principle calculating first order is 83.35 Ω, the isolation resistance of the second level is 60 Ω.
Carry out CAD drawing to described power splitter, according to simulation parameter, the printing layout extraction be depicted as by CAD imports to the HFSS 3 D electromagnetic simulation software emulation of Ansoft company, by simulating, verifying correctness of the present invention.
The power splitter of the present invention's composition, indices is better, and structure is simple, and volume is little and have very high reliability, therefore has very strong practicality and competitiveness.
Be more than the description to the present invention and embodiment thereof provided to the engineers and technicians being familiar with field of the present invention, these descriptions should be considered to be illustrative, but not determinate.Engineers and technicians the thought accordingly in invention claims can do concrete operation and implement, and naturally also can do a series of change according to the above to embodiment.And the present invention is not limited to 2100 ~ 2400MHz, structure of the present invention can be transplanted on other different frequency range or more wide band power splitter naturally, and above-mentioned these all should be regarded as coverage of the present invention.
The content be not described in detail in specification of the present invention belongs to the known technology of professional and technical personnel in the field.
