; The utility model can be realized the bandwidth of band, can be widely used in 5G mobile communication power splitter etc. to the strict place of signal performance requirement.Can reduce passband external noise, improve the stability of electronic circuit.
Description
Technical field
The utility model belongs to transformer application field, particularly one and realizes broadband impedance transformer.
Background technology
In field transformer, improving the anti-short ability of transformer is to improve the key measure of operation of power networks reliability, and high broadband impedance transformer is because its short-circuit capacity is compared with the favor that is day by day subject to by force power consumer.In the last few years, carried out a series of research about transformer both at home and abroad.Obtain a lot of achievements in research, be especially used in mobile communication technology, used at broadband impedance transformer and can effectively solve that system linear degree is low, narrow bandwidth, problem that passband external noise is large.But its project organization can only use in specific frequency range, and bandwidth is less, signal attenuation is larger, causes having to increase the number of power amplifier, makes system bulk larger, versatility is not strong.Simultaneously traditional transformer is due to the problem of its structure, makes temperature sensitivity extremely strongly, and applicability is very limited.The utility model, for above problem, can effectively solve, and to meet system requirements, and stability is high, volume is little, processing is simple, applied widely.
Summary of the invention
The utility model provides a kind of have ultra broadband, the broadband impedance transformer that simple in structure, volume is little, stability is high.
The technical scheme that realizes the utility model object is: a kind of broadband impedance transformer, comprises by two multiport transformer XF1 and XF2, two parallel resonator unit
and two complex impedances
realize.Wherein, impedance
two ends be connected with the two ends of transformer XF1 respectively, 3 ends of transformer XF1 and 4 ends respectively with parallel resonance unit
two ends be connected; Parallel resonance unit
two ends be connected with 4 ends with 5 ends of transformer XF1; 4 ends of transformer XF1 and 5 ends respectively with parallel resonance unit
two ends be connected; Parallel resonance unit
two ends be connected with 3 ends with 4 ends of transformer XF2; Two complex impedances
be 50 ohm.
Compared with prior art, the utility model provides a kind of have broadband, the feature that simple in structure, volume is little, stability is high.
