Embodiment 1

[0046] We design a card-type multi-channel digital receiving module by using the button array with compact pins and adjustable connection height as the board-to-board connector. A compact high-speed digital receiving module, including 2 control and data processing sub-boards, 2 analog-to-digital conversion sub-boards and a clock management and power management sub-board, such as figure 1 shown. Each board adopts button array to interconnect the high-speed digital differential signal and power supply between the boards. The analog-to-digital conversion sub-board receives the intermediate frequency signal transmitted by the antenna and the frequency conversion part through the button array, and after sampling through the high-speed ADC, transmits the high-speed differential digital signal to the control and data processing sub-board through the button array. The maximum transmission rate of the fur button array can reach 12Gbps.

[0047] The clock management and power manageme...

Embodiment 2

[0053] In the application of detection systems with high precision and wide scanning range, a single antenna unit can no longer meet the requirements, and x*y antenna units are required to form an antenna array to meet the application requirements. Wherein, the aperture area of ​​a single antenna is a*b, and the area of ​​the antenna front is (a*x)*(b*y). Each antenna unit contains a digital receiver module. The digital receiving module is composed of 5 sub-boards, each sub-board has a width of b, and the total thickness of the 5 sub-boards is a when they are stacked in parallel. They are vertically interconnected with the antenna and the frequency conversion module to form an antenna unit, such as figure 2 shown. On the whole, one side of the digital receiving module is connected to the antenna and frequency conversion module to receive the radio frequency signal to be sampled and provide coherent clock and wave control for the front end; the other side is connected to the ...

Abstract

The invention provides an adjustable fuzz button array data receiving device and method, and the device comprises an adjustable fuzz button array which is a specification-adjustable signal transmission device and is used for adjusting the installation aperture parameter of the adjustable fuzz button array so as to adapt to the installation parameter of the adjustable fuzz button array, an antenna frequency conversion module and a sub-board module; the antenna frequency conversion module is a signal receiving device; the daughter board module is an integrated signal processing device and is vertically coupled to the antenna frequency conversion module; the analog-to-digital conversion daughter board is used for sampling and processing a wireless signal so as to obtain and send a high-speed differential digital signal to the control and data processing daughter board; the control and data processing daughter board is used for receiving and transmitting the high-speed digital differential signal; and the clock management and power management daughter board is used for providing a sampling clock, a system clock and various power supplies for the analog-to-digital conversion daughter board and the control and data management daughter board. The data receiving device has the advantages that interconnection is achieved through the adjustable fuzz button array, and the same aperture, expansion and reconstruction of the data receiving device are achieved.

Description

technical field [0001] The present invention relates to a compact high-speed digital receiving module, in particular to an adjustable hair button array data receiving device and method that can be used in a miniaturized high-speed analog-to-digital conversion and signal processing system. Background technique [0002] For applications in broadband, high-speed, multi-channel digital receiving systems, multiple analog-to-digital conversion chips and FPGAs with high sampling rates are often required; requirements for the integration, scalability, reconfigurability, and modularization , and the digital receiving system needs to have the same aperture as the antenna unit. Patent No. CN203827598U's invention "A Microwave Vertical Interconnection Circuit Connected by Buttons" adopts the microwave vertical interconnection circuit connected by buttons, and uses each group of buttons arranged in 3×4 to connect the LTCC substrate and the pin-planting PCB distribution board. Use the fu...
