Embodiment 1

[0021] as attached figure 1 , 2 As shown, the installation module composed of LTCC components and structural cavity in this embodiment includes structural cavity 1 and LTCC component 2, as attached image 3 As shown, the structural cavity 1 is composed of symmetrical structural plates 11 on the front and back sides, and the surfaces of the structural plates 11 on both sides are provided with weight-reducing grooves 111. The interior of the structural cavity 1 is a hollow cavity for accommodating electronic components. The lower part of the surface of the front and back structural plates 11 has an installation groove 112 for installing LTCC components, and the area of ​​the installation groove 112 is provided with a threaded hole 113, and the orifice of the threaded hole 113 is raised; as attached Figure 4 As shown, the LTCC assembly 2 includes an LTCC template 21 and a tungsten copper plate 22 welded on the back of the LTCC template 21. The left and right edges of the LTCC a...

Abstract

The invention relates to the technical field of designing of a T / R component in active phased array radar, in particular to a mounting module composed of an LTCC component and a structure cavity. The mounting module comprises the structure cavity and the LTCC component. A thread hole is formed in a mounting groove zone for mounting the LTCC component on the surface of a structure plate, namely a component of the structure cavity, in addition, the LTCC component composed of a tungsten copper plate is welded to the back of an LTCC template, a mounting hole is formed in the edge of the LTCC template, the mounting hole is in a semicircular shape, and the radius of a mounting hole in the tungsten copper plate is smaller than that of the mounting hole in the LTCC template. The mode that the tungsten copper plate is pressed through a screw is used for fixing the LTCC component to a mounting groove in the structure plate, through the fixing mode, the LTCC template can be maintained and replaced conveniently, the LTCC template cannot be damaged easily, the tungsten copper plate and the structure plate are arranged through a screw, a certain gap exists, in high-low-temperature working environments, micro expansion / contraction of the tungsten copper plate and the structure plate cannot be limited, and the LTCC template cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of design of T / R components in an active phased array radar, in particular to an installation module composed of an LTCC component and a structural cavity. Background technique [0002] Since the advent of radar in the 1930s, radar technology has achieved rapid development in the Second World War. After the 1990s, active phased array radar has become the mainstream of radar development. Each active phased array radar contains a number of T / R components, which not only complete the receiving task but also complete the transmitting task, and also perform phase scanning on the antenna. Each T / R component is equivalent to a high-frequency head of an ordinary radar. It includes not only a transmitting power amplifier, but also a low-noise amplifier, a phase shifter, and a beam control circuit. Filtering can be added to the receiving channel if necessary. The filter is used to suppress external interference signa...
