Description
Technical field
The utility model relates to electronic communication field, particularly a kind of low-frequency range one-to-two power splitter for microwave communication, satellite communication, electronic equipment etc.
Background technology
Existing VHF frequency range is to UHF low-frequency range power divider, mainly there are the problems such as technological obsolescence, technical indicator comparatively fall behind, specifically mainly be reflected in the low frequency deficiency, the aspect such as volume is large, weight is large and reliability is relatively poor, also difficulty is made in existence simultaneously, failure rate is higher, is difficult to satisfy the problems such as ROUHS standard.
Summary of the invention
The utility model is intended to solve the technical problems such as existing low-frequency range power divider exists that low frequency is not enough, volume is large, weight is large and reliability is relatively poor, so that the low-frequency range one-to-two that a kind of output frequency is low, volume is little, lightweight and reliability is high power splitter to be provided.
The purpose of this utility model is achieved through the following technical solutions.
Low-frequency range one-to-two power splitter of the present utility model, the input of impedance matching box 1 connects signal input part, its output connects power match device 3, two outside output signals of output of power match device 3, and between two outputs, cross-over connection has impedance matching box 24; One end span of electric capacity adaptation 2 is connected between impedance matching box 1 and power match device 3, its other end ground connection.
Low-frequency range one-to-two power splitter of the present utility model, wherein said impedance matching box 1 is the 1:4 wire-wound magnetic core, power match device 3 is the 1:1 wire-wound magnetic core.
The beneficial effect of the utility model low-frequency range one-to-two power splitter:
1. has output frequency in the VHF frequency range to the UHF low-frequency range low;
2. volume is little, lightweight, reliability is high;
3. be easy to manufacturing, failure rate is low, satisfy the ROUHS standard.

The number in the figure explanation:
1 impedance matching box one, 2 electric capacity adaptations, 3 power match devices, 4 impedance matching boxs two
Embodiment
The utility model detailed construction, application principle, effect and effect with reference to accompanying drawing 1, are explained by following execution mode.
Consult shown in Figure 1, low-frequency range one-to-two power splitter of the present utility model, the input of impedance matching box 1 connects signal input part, and its output connects power match device 3, two outside output signals of output of power match device 3, between two outputs, cross-over connection has impedance matching box 24; One end span of electric capacity adaptation 2 is connected between impedance matching box 1 and power match device 3, its other end ground connection.Impedance matching box 1 is the 1:4 wire-wound magnetic core, and power match device 3 is the 1:1 wire-wound magnetic core.
Signal enters from input, after impedance matching box 1 and electric capacity adaptation 2, tells two-way phase place, the consistent signal of loss by power match device 3 distributor circuits.
Many technological merits such as therefore low-frequency range one-to-two power splitter of the present utility model is operated in the VHF frequency range to the UHF low-frequency range, and output frequency is low, volume is little, lightweight and reliability is high.
