[0032] Mounting box 1 is mainly used to install radio frequency front-end components;

[0033] Cover plate 101 is mainly used to seal the installation box 1;

[0034] Mounting slot 102 is mainly used for mounting snap-fit ​​components;

[0036] Example 2: Figure 2As shown, the active phased array radar radio frequency front-end disclosed in Embodiment 2 of this utility model has a structure that is basically the same as that in Embodiment 1. The difference is that the radio frequency front-end assembly includes a radio frequency amplifier 2, which is installed at the bottom of the inner cavity of the mounting box 1. A mixer 201 is installed at the bottom of the inner cavity of the mounting box 1 outside the radio frequency amplifier 2. A local oscillator 202 is installed at the bottom of the inner cavity of the mounting box 1 outside the mixer 201. An amplifier 203 is installed at the bottom of the inner cavity of the mounting box 1 outside the local oscillator 202. A filter 204 is installed at the bottom of the inner cavity of the mounting box 1 outside the amplifier 203. The amplifier 203 and the filter 204 are connected by a magnetic coupling element 205. Optical couplers 206 are installed at the top of both the mixer 201 and the amplifier 203. A circuit board 207 is installed at the bottom of the inner cavity of the mounting box 1.

[0037] The radio frequency amplifier 2 uses high-temperature superconducting materials to reduce energy loss and improve overall performance;

[0038] Mixer 201 is mainly used to mix the received radio frequency signal with the local oscillator signal generated by local oscillator 202 to generate an intermediate frequency signal;

[0039] The local oscillator 202 is mainly used to generate a stable local oscillator signal for use by the mixer 201;

[0040] By setting up the magnetic coupling element 205, the radio frequency signal can be transmitted between the amplifier 203 and the filter 204 without physical contact, thereby reducing signal attenuation and energy loss.

[0041] By setting up the optical coupler 206, which mainly connects the mixer 201 and the amplifier 203, efficient and low-loss signal transmission is achieved through optical signal transmission.

[0042] The magnetic coupling element 205 and the optical coupler 206 use optical coupling technology to realize signal transmission between internal components of the radio frequency front end, reducing signal attenuation and energy loss.

[0043] First, the RF amplifier 2 receives the RF signal from the antenna and amplifies it. Then, the mixer 201 mixes the amplified RF signal with the local oscillator signal generated by the local oscillator 202 to obtain the intermediate frequency signal. Next, the intermediate frequency signal is filtered and amplified by the filter 204 and the amplifier 203, and finally sent to the receiver for processing.

[0045] Example 3: Figure 3As shown, the active phased array radar radio frequency front-end disclosed in Embodiment 3 of this utility model has a structure that is basically the same as that in Embodiment 1. The difference is that the snap-fit ​​assembly includes a rectangular block 3, which is installed in the inner cavity of the mounting groove 102.

A spring 303 is installed on the opposite side of the snap-fit ​​blocks 302.

[0046] When it is necessary to open the cover 101, since there are two sets of locking components, when one set of locking components is pressed inward, the locking block 302 moves relative to the other and the spring 303 is compressed, thereby disengaging the locking block 302 from the inner cavity of the mounting box 1, so that the cover 101 can be opened from one side. When the locking block 302 of the other set of locking components is pressed, the cover 101 can be opened from the other side, so that the cover 101 can be opened from either side.

[0047] When both sets of snap-fit ​​components are pressed simultaneously, the cover plate 101 can be disassembled.

[0048] Example 4: Figure 2 As shown, the active phased array radar radio frequency front-end disclosed in Embodiment 4 of this utility model has a structure that is basically the same as that in Embodiment 1. The difference is that the radio frequency front-end component is made of high-temperature superconducting material.

[0049] By using high-temperature superconducting materials in the radio frequency front-end components, the energy loss of the radio frequency front-end during operation is reduced, thereby improving the overall performance of the components.

[0050] Example 5: Figure 1 As shown, the active phased array radar radio frequency front-end disclosed in Embodiment 5 of this utility model has a structure that is basically the same as that in Embodiment 1. The difference is that grooves 4 are provided on both sides of the cover plate 101.

[0051] By providing the groove 4, when the cover 101 is closed, the user can lift the mounting box 1 through the groove 4.

[0052] Example 6: Figure 2 As shown, the active phased array radar radio frequency front-end disclosed in Embodiment Six of this utility model has a structure that is basically the same as that in Embodiment One. The difference is that the radio frequency front-end components are arranged closely in a horizontal direction.

[0053] like Figure 2 As shown, the radio frequency front-end components are tightly arranged in the same plane using three-dimensional integrated circuit technology, achieving horizontal miniaturization.

[0054] Example 7: Figure 1As shown, the active phased array radar radio frequency front-end disclosed in Embodiment 7 of this utility model has a structure that is basically the same as that in Embodiment 1. The difference is that a reserved hole 5 is provided at the top of the connecting plate 103.

[0055] By setting the reserved hole 5, the inner cavity of the reserved hole 5 is mainly used for installing bolts to fix the inner cavity of the mounting box 1.

[0056] Example 8: Figure 3 As shown, the active phased array radar radio frequency front-end disclosed in Embodiment 8 of this utility model has a structure that is basically the same as that in Embodiment 3. The difference is that one end of the card block 302 is engaged with the inner cavity of the mounting box 1.

[0057] The specific solution is as follows: First, the RF amplifier 2 receives the RF signal from the antenna and amplifies it. Then, the mixer 201 mixes the amplified RF signal with the local oscillator signal generated by the local oscillator 202 to obtain the intermediate frequency signal. Next, the intermediate frequency signal is filtered and amplified by the filter 204 and the amplifier 203, and finally sent to the receiver for processing. When it is necessary to open the cover 101, since there are two sets of snap-fit ​​components, when one set of snap-fit ​​components is pressed inward, the snap-fit ​​component 302 moves relative to the snap-fit ​​component and the spring 303 is compressed, thereby causing the snap-fit ​​component 302 to disengage from the inner cavity of the mounting box 1, so that the cover 101 can be opened from one side. When the snap-fit ​​component 302 of the other set of snap-fit ​​components is pressed, the cover 101 can be opened from the other side, so that the cover 101 can be opened from either side. When both sets of snap-fit ​​components are pressed at the same time, the cover 101 can be disassembled.
