Description

Technical Field

[0001] This utility model relates to the field of radio frequency front-end test platforms, specifically a signal receiving and processing device for radio frequency front-end test platforms. Background Technology

[0002] RF front-end chip testing systems are specialized testing equipment for highly complex integrated circuit designs. These systems are primarily used for testing mobile application processors, digital baseband processors, and high-data-rate RF transceivers. With the rapid development of modern wireless communication technologies such as 5G, IoT, and autonomous driving, the RF front-end module, as a core component of wireless devices, directly impacts signal transmission quality and overall device functionality. As a key device for verifying and optimizing module performance, RF front-end testing platforms place higher demands on testing accuracy, stability, and maintenance efficiency. Existing RF front-end testing platforms' signal receiving and processing devices suffer from the following technical challenges in practical applications:

[0003] Traditional devices often employ a one-piece or multi-bolt-fixed casing. Repairing or replacing internal components requires disassembling numerous screws or using specialized tools to separate the casing, making the process cumbersome and time-consuming. This not only reduces equipment maintenance efficiency but can also lead to problems such as stripped threads and casing deformation due to frequent disassembly, further impacting the equipment's lifespan. Some devices with a modular design have weak locking mechanisms or unreliable locking methods, making them prone to loosening and casing separation under prolonged use or external vibration. This not only exposes internal components to dust and moisture but can also cause signal interference, affecting the accuracy of test results.

[0004] During testing, components such as high-speed circuits and cooling fans inside the device will vibrate. If there is no effective buffer and energy absorption structure, the vibration will not only accelerate the aging of components, but also generate noise pollution through the cover shell 4. Especially in precision testing environments, noise may interfere with the detection of weak signals, reduce test resolution and reliability. Therefore, it is necessary to design a signal receiving and processing device for the RF front-end test platform to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figure 1-5As shown, this utility model provides a signal receiving and processing device for an RF front-end test platform, including a frame 1. A support member for supporting a mounting shell 2 is fixedly installed on the inner side of the frame 1. The support member is used to absorb and dissipate the dynamic potential energy of vibration. Fixing plates 3 are fixedly connected to the top of the mounting shell 2 and near both sides. A cover shell 4 is snapped onto the top of the mounting shell 2. The cover shell 4 and the mounting shell 2 are both U-shaped and interlocked. Locking fasteners for fixing the cover shell 4 are installed on both sides of the frame 1. A signal receiving and processing module is installed on the bottom inner side of the mounting shell 2.

[0025] It should be added that frame 1 is a rectangular ring, and the support is installed and fixed to frame 1 by multiple bolts. The support supports the mounting shell 2 and cover shell 4. The support can also absorb and dissipate kinetic energy, reduce the sway amplitude of the support and reduce noise, and avoid the signal processing module being affected by vibration, which would cause inaccurate testing. The locking fasteners can lock and fix cover shell 4, mounting shell 2 and frame 1, improving the convenience and stability of disassembling and assembling cover shell 4.

[0026] Specifically, the signal receiving and processing module includes an RF front-end module, a frequency conversion module, an intermediate frequency (IF) processing module, and a digital processing module. The module's collaborative workflow is as follows: Signal reception: Antenna captures RF signal → LNA amplification → Filter suppresses interference; Frequency conversion: Mixer converts RF signal to IF → LO provides local oscillator signal; Intermediate frequency processing: IF amplifier amplifies → IF filter performs fine filtering; Digital processing: ADC sampling → DDC down-conversion → DSP / FPGA performs digital signal processing; Data output: Processing results are transmitted to the test system via interface; Control feedback: MCU configures the parameters of each module according to the host computer's instructions.

[0027] More specifically, the support components include a support frame 5 fixedly connected to the inside of the frame 1, a pad 6 fixedly connected to the top of the support frame 5 for supporting the mounting shell 2, a plurality of evenly arranged support feet 7 fixedly connected to the bottom of the support frame 5, a plurality of rectangularly arranged shock absorbers 8 fixedly connected to the inside of the support frame 5, springs 9 being fitted on the outside of the shock absorbers 8, the two ends of the support frame 5 being installed and fixed by a plurality of bolts, a plurality of evenly arranged support strips 18 fixedly connected to the inside of the support frame 5, and anti-slip pads 20 being laid on the bottom of the support feet 7.

[0028] It should be supplemented that the support frame 5 is installed and fixed to the frame 1 by bolts. The backing plate 6 can be fitted to the mounting shell 2. The support feet 7 support the mounting shell 2 on the top of the backing plate 6 through the support frame 5. The shock absorber 8 in the support frame 5 can absorb and consume the dynamic potential energy generated by the vibration of the support frame 5 and reduce the swaying amplitude of the mounting shell 2. The spring 9 and multiple support bars 18 can support the support frame 5 to increase the compressive strength of the support frame 5. The anti-slip pads 20 at the bottom of the support feet 7 can increase the anti-slip property of the support feet 7.

[0029] Furthermore, the locking fastener includes movable cavities 10 respectively opened on both sides of the cover housing 4. A sliding plate 11 is slidably connected to the inner side of the movable cavity 10. A plurality of sliding rods 12 arranged uniformly are fixedly connected to one side of the sliding plate 11. An elastic frame 13 is fixedly connected between the sliding plate 11 and the movable cavity 10. Two groups of locking columns 14 arranged uniformly are fixedly connected to the other side of the sliding plate 11. A plurality of locking grooves 15 arranged uniformly are respectively opened on both sides of the mounting shell 2 and both sides of the cover housing 4. Each group of locking columns 14 includes multiple ones, and the locking columns 14 and the locking grooves 15 correspond to each other one by one. Fixed grooves 16 are respectively fixedly connected to both sides inside the cover housing 4. A fixing strip 17 is fixedly connected to one side of the fixing plate 3. The fixed grooves 16 and the fixing strip 17 are slidably connected. A plurality of elastic pieces 19 arranged uniformly are fixedly connected to the inner side of the elastic frame 13.

[0030] Among them, the elastic frame 13 in the movable cavity 10 can push the sliding plate 11 by extrusion. The sliding rods 12 can respectively drive the multiple locking columns 14 on one side of the sliding plate 11 to insert into or disengage from the locking grooves 15. The multiple elastic pieces 19 can push the elastic frame 13 by extrusion to increase the strength of the locking columns 14 on one side of the sliding plate 11 embedded in the locking grooves 15. The cross-sections of the fixed grooves 16 and the fixing strip 17 are both "convex" shaped to increase the stability of the fixed grooves 16 embedded in the fixing strip 17.

[0031] Working principle: First, the cover housing 4 is snapped onto the top of the mounting shell 2. At this time, the fixed grooves 16 are embedded in the fixing strip 17. Then, the sliding rods 12 are slowly released. At this time, the multiple elastic pieces 19 push the elastic frame 13 by extrusion. At the same time, the elastic frame 13 pushes the locking columns 14 on one side of the sliding plate 11 by extrusion. Then, the two groups of locking columns 14 are respectively inserted into the locking grooves 15 on one side of the mounting shell 2 and the cover housing 4. Then, the support feet 7 are placed on the operating table. The support feet 7 support the mounting shell 2 on the top of the backing plate 6 through the support frame 5. At the same time, the shock absorber 8 in the support frame 5 absorbs and consumes the dynamic potential energy generated by the vibration of the support frame 5 and reduces the swaying amplitude of the mounting shell 2.
