Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
The utility model provides Integrative Radar frequency microwave assembly, and as shown in Figure 2 to 4, this assembly comprises intermediate plate, active parts and metal shielding board.The one side of intermediate plate is processed into active parts cavity 1, another side is processed into passive component.The degree of depth of active parts cavity 1 is 7.9mm.Active parts comprises transceiver channel and frequency source, and be installed in active parts cavity, metal shielding board covers on active parts cavity.Passive component comprises cavity body filter and cavity circulator.Passive component is processed with four kinds of cavitys altogether, the first cavity 4 the degree of depth be 6.9mm, the degree of depth of the second cavity 5 is 0.5mm, and the degree of depth of the 3rd cavity 6 is 4.5mm, and the degree of depth of the 4th cavity 7 is 1.2mm.
Be provided with dividing plate 2 in active parts cavity 1, the upper surface of dividing plate 2 flushes with intermediate plate integral surface.Dividing plate 2 and intermediate plate are integral type structure, are separated between each active parts by dividing plate 2.Intermediate plate is provided with through hole 3.
Passive and active parts merge and integration by the utility model, are integrated in an intermediate plate.Mainly through carrying out NC milling to monoblock magnalium plate blank material both sides, form two cavitys, a cavity is provided with source block (comprising transceiver channel, frequency source), another cavity is directly processed into passive component (comprising cavity body filter, cavity circulator), and centre is for fixing and heat radiation.
This frequency microwave Components integration degree is very high, and heat density is comparatively large, in order to improve component operation stability and reliability, should be noted heat radiation.Because passive component is to temperature-insensitive, also substantially can not produce heat, after passive component and active parts integration, substantially do not have thermal resistance, passive component may be used for the heat radiation of active parts.
The utility model also provides the method for making of Integrative Radar frequency microwave assembly, and the method comprises the following steps:
(1) first by the one side of a monoblock magnalium blank according to the structure of passive component, carry out numerical control milling, form a cavity;
(2) another side of this magnalium blank being processed into active parts cavity, when being processed with source block cavity, reserving corresponding dividing plate according to the size of each active parts;
(3) active parts is arranged in active parts cavity, covers metal electric barricade.
The utility model method is specifically implemented as follows:
Frequency microwave modular construction cavity is made up of active parts cavity and passive component cavity, signal as shown in Figure 2, cavity processing mainly comprises the processing of passive component (comprising cavity body filter, cavity circulator) cavity and active parts (comprising transceiver channel, frequency source), for the passive component of high band, inside cavity need ensure machining precision and surfaceness.
Passive component is directly made up of cavity, and the inside is without any other device.First by the one side of magnalium blank according to passive component structure as shown in Figure 3, carry out numerical control milling, form a cavity, this cavity has higher machining precision and the requirement of surfaceness.
Finally be processed with source block face, its structural drawing as shown in Figure 4, because transceiver channel and frequency source are put together by active parts, device density is higher, structure is more complicated, and in assembly, comprise multiple functional module, for the outside radiated electromagnetic wave of reduction module causes the electromagnetic effect to other module, when carrying out NC milling to cold drawing, corresponding dividing plate is reserved according to the size of each module, machining stress will be reduced simultaneously, ensure machining precision, cold drawing is avoided to be out of shape warpage, reduce cold drawing surfaceness, to reduce the thermal contact resistance of radio frequency component, improve radiating efficiency.Assembly voltage plane and radio frequency surface cover adopt metal electric barricade, metal shielding board is for shielding electromagnetic leakage, the outside radiated electromagnetic wave of reduction module causes the electromagnetic effect to other parts, and metal shielding board has excellent physical strength and rigidity simultaneously, prevents due to stress deformation or damage, shell has certain degree of protection, prevent human body from touching or close to live part, prevent from causing deleterious effect into water, structural member surface Nickel Plating Treatment, improve corrosion resistivity, ensure long-term low resistance connection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
