Description
Technical field
The utility model relates to a kind of rectification circuit being applied to microwave energy transfer and Environmental Microwave energy acceptance, particularly relates to a kind of multi-frequency micro-wave rectification circuit.
Background technology
The flying power of battery is a difficult problem for all kinds of intelligent terminal, is also a difficult problem for the sustainable work of wireless senser.How Present Domestic is outer all passes through energy unnecessary in capturing ambient in research, as luminous energy, the temperature difference and vibration homenergic, to convert electric energy to for low power dissipation electron device continuous firing.The energy of catching from environment be continue and free, along with the continuous reduction of components and parts energy consumption, the application prospect of these energy is unanimously had an optimistic view of by everybody.In fact, a kind of invisible energy---microwave is also had around us, microwave energy is free with its mobility, green, and be not subject to the advantages such as the impact of environment round the clock, obtain research extensively and profoundly at home and abroad, to becoming " giving up " into precious, being converted into utilizable electric energy, is various mobile power supply equipment.
The frequency distribution of Environmental Microwave is more wide in range, is mainly distributed in 800-900MHz, 1.7-2.7GHz and 5-6GHz etc., in so wide frequency band, if directly carry out impedance matching to rectifier diode, is impossible substantially.In order to unit are obtains maximum power, be separated with regard to needing the signal received antenna and multifrequency coupling.The research in power amplifier of single channel multi-frequency impedance coupling is many, if be applied in the rectification of Environmental Microwave energy, is difficult to the rectification work realizing multifrequency in a short time.
Current multifrequency and ultra broadband rectification circuit directly diode are received on ultra-wideband antenna, it is allowed directly to carry out the conversion of signal, there is following shortcoming in it: 1) signal input part does not have filter, is difficult to carry out harmonics restraint, reduces the rectification efficiency of diode; 2) there is no impedance inverter circuit, impedance matching can not be carried out to diode, can not high efficiency rectification be realized.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of multi-frequency microwave rectification circuit being applied to microwave energy transfer and Environmental Microwave energy acceptance, to realize the multifrequency coupling of rectifier diode input impedance matching circuit, realize the filtering of input signal, in order to harmonic inhabitation simultaneously.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of multi-frequency micro-wave rectification circuit, comprise input matching network and rectifier diode, described input matching network comprises power splitter, the bank of filters that the impedance transformer group be made up of multiple impedance transformer and multiple filter form, described power splitter comprises an input for microwave input and at least two outputs, each output of power splitter is connected with the input of each impedance transformer, the output of each impedance transformer is connected with the input of each filter, the output of all filters forms a common port exported for direct current, the negative pole of described rectifier diode connects described common port, the plus earth of described rectifier diode.
Compared with prior art, the utility model has the advantage of that the input matching network multilink of rectifier diode works alone, to realize multifrequency or ultra broadband.Diode has different impedances in different frequencies, and the effect of input matching circuit is exactly the working impedance of the input impedance conversion of diode to system, if communication system is 50 ohm, just applies match circuit the impedance transformation of amplifier tube to 50 ohm.But the technology such as common composite left-and-right-hand are difficult to the multifrequency coupling realizing characteristic frequency.And impedance extraction is carried out with multiple filter respectively in the both sides of diode, namely mixer technology realizes, and mixer can realize the impedance-tumed of different frequency, and namely solution common port carries out separately the mutual of impedance matching affects problem.For the input of diode, with impedance transformer, the impedance transformation of filter input end is become system impedance, and be connected with each road of power splitter, achieve the single input of overall input impedance matching circuit and single output, and can multifrequency mate separately.Compare with super-broadband tech with existing multifrequency, the beneficial effects of the utility model are: 1) can either realize multifrequency rectification, also can realize ultra broadband rectification; 2) impedance transformation can be carried out to the impedance of the multiple special frequency channel of diode; 3) can harmonics restraint be realized, improve the rectification efficiency of diode.
