Abstract
The utility model relates to an equalizer and in particular relates to a miniaturized equalizer, comprising a first microwave radio-frequency joint and a second radio-frequency microwave joint, wherein the first microwave radio-frequency joint and the second radio-frequency microwave joints are fixedly arranged on a first connection plate and a second connection plate. A telescopic connection piece is connected between the first connection plate and the second connection plate. The miniaturized equalizer provided by the utility model has the advantages of small size, light weight, simple structure, convenient use, low cost and high reliability and can be widely applied to various radar-signal simulator systems and radar electronic-countermeasures systems. With development of a radar technology, the miniaturized equalizer will have a relatively wide application scope.
Description
Technical field
The utility model relates to equalizer, specifically is a kind of miniaturization equalizer.
Background technology
At present, wide-band microwave radio frequency analog device is because signal band is wideer, and the response of the Frequency and Amplitude of various microwave radio devices is all different, has caused the imbalance of output signal power amplitude, for the wasting of resources of the last power amplifier of system.Technical staff's processing method adds amplitude equalizer or a saturated amplification output signal that volume is bigger often in link in actual applications, now just towards the development of miniaturization integrated direction, above method can not well be pressed close to this trend to the microwave radio simulation system.
The utility model content
Primary and foremost purpose of the present utility model is to provide a kind of volume little, in light weight, simple in structure, easy to use, with low cost, the miniaturization equalizer that reliability is high, and concrete scheme of the present utility model is as follows for achieving the above object:
A kind of miniaturization equalizer comprises:
The first microwave radio joint, the second frequency microwave joint, the described first microwave radio joint, the second frequency microwave joint are fixedly arranged on first connecting plate, second connecting plate respectively;
Be connected by scalable connector between described first connecting plate and described second connecting plate.
Preferably, described scalable connector is connected to tuning screw.
The miniaturization equalizer volume that the utility model provides is little, in light weight, simple in structure, easy to use, with low cost, the reliability height can be widely used in various radar signal simulator systems and radar electric countermeasure system, along with the development of Radar Technology, this utility model will have more wide applications.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment
As shown in Figure 1, a kind of miniaturization equalizer, the first microwave radio joint 11, the second frequency microwave joint 12, the first microwave radio joint 11, the second frequency microwave joint 12 are respectively equipped with the gold-plated joint 13 that is oppositely arranged, be respectively equipped with winding by hand inductance coil 14 on the gold-plated joint 13, the described first microwave radio joint 11, the second frequency microwave joint 12 are fixedly arranged on first connecting plate 21, second connecting plate 22 respectively; Be connected by scalable connector between described first connecting plate 21 and described second connecting plate 22, as the preferred version in the present embodiment, described scalable connector is tuning screw 3.
The operation principle of this equalizer adopts the LC oscillation circuit to form the high frequency high pass filter of single order, make working frequency range be in outside the low-frequency band of high pass filter, form reflection echo, with more the reflecting back of the signal of lower frequency, thereby reach the effect little to the high-frequency signal Insertion Loss greatly to the low frequency signal Insertion Loss, reach the purpose of balanced broadband signal power magnitude.Wherein the micro gap between two joints is as the electric capacity in the circuit, and available tuning screw 3 adjusts its stiffness of coupling, winding by hand inductance coil 14 analogue ground inductance, thus form the LC oscillation circuit.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
