Abstract
The utility model discloses a kind of C-band band pass filter, wherein, half lumped wave filter and microstrip filter are located in described printed board respectively, soldering of printed boards is in main cavity, upper cover plate is seal-installed on the opening of main cavity, input connector and out connector are located at the two ends of main cavity respectively, and input connector, half lumped wave filter, microstrip filter and out connector are electrically connected successively.The utility model with half lumped wave filter for high pass filter, take microstrip filter as low pass filter, high pass filter and low pass filter can require to select different frameworks according to different suppression, redundant circuit is less, flexible design is convenient, can obtain surveying index comparatively accurately by the design of Simulation of routine, so be easy to debugging; Half lumped wave filter, microstrip filter and printed board are placed in main cavity, are beneficial to and reduce volume and improve signal shielding effect.
Description
Technical field
The utility model relates to a kind of band pass filter, particularly relates to a kind of C-band band pass filter.
Background technology
One section of frequency band of C-band to be frequency be 4.0-8.0GHz, as the frequency range of communication satellite downstream transmission signals.C-band band pass filter is a Primary Component in electronic communication application, for selecting the useful signal of system requirements in the electromagnetic environment of complexity, filters out unwanted useless interference simultaneously, reduces system to the response of unwanted signal.
, there is following shortcoming in traditional C-band band pass filter:
1., when low frequency, because the volume of microstrip capacitor is comparatively large, the volume of whole filter is bigger than normal;
2. lumped wave filter is when designing, and owing to being difficult to obtain model comparatively true to nature, the debugging difficulty of final filter is larger.
Utility model content
The purpose of this utility model being just to provide a kind of small volume to solve the problem, being easy to the C-band band pass filter of debugging.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of C-band band pass filter, comprise main cavity, printed board, upper cover plate, input connector, half lumped wave filter, microstrip filter and out connector, described half lumped wave filter and described microstrip filter are located in described printed board respectively, described soldering of printed boards is in described main cavity, described upper cover plate is seal-installed on the opening of described main cavity, described input connector and described out connector are located at the two ends of described main cavity respectively, described input connector, described half lumped wave filter, described microstrip filter and described out connector are electrically connected successively.
As preferably, the electric capacity of described half lumped wave filter is lumped parameter patch capacitor, and inductance is micro-band inductance.
All connected by bead between described input connector and described printed board, between described printed board and described out connector.
The beneficial effects of the utility model are:
The utility model with half lumped wave filter for high pass filter, take microstrip filter as low pass filter, high pass filter and low pass filter can require to select different frameworks according to different suppression, redundant circuit is less, flexible design is convenient, can obtain surveying index comparatively accurately by the design of Simulation of routine, so be easy to debugging; Half lumped wave filter, microstrip filter and printed board are placed in main cavity, are beneficial to and reduce volume and improve signal shielding effect.
Accompanying drawing explanation
Fig. 1 is the circuit structure block diagram of C-band band pass filter described in the utility model;
Fig. 2 is the overall structure schematic diagram of C-band band pass filter described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, C-band band pass filter described in the utility model comprises main cavity 3, printed board 5, upper cover plate 4, input connector 1, half lumped wave filter (not showing in Fig. 2), microstrip filter (not showing in Fig. 2) and out connector 6, half lumped wave filter and microstrip filter are also located in printed board 5 respectively as high pass filter and low pass filter respectively, printed board 5 is welded in main cavity 3, upper cover plate 4 is seal-installed on the opening of main cavity 3, input connector 1 and out connector 6 are located at the two ends of main cavity 3 respectively, input connector 1, half lumped wave filter, microstrip filter and out connector 6 are electrically connected successively, wherein, the electric capacity of half lumped wave filter is lumped parameter patch capacitor, and inductance is micro-band inductance, all connected by bead 2 between input connector 1 and printed board 5, between printed board 5 and out connector 6.
Printed board 5 is directly welded on main cavity 3, does not need other devices to fix, more can save space.After having debugged, carry out closed shield by upper cover plate 4, whole filter is in the shielding main cavity 3 of a sealing.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
