Description

Technical Field

[0001] This utility model relates to the field of signal generation module technology, and in particular to a multi-band synthesized signal generation circuit module. Background Technology

[0002] Signal generators are used to produce electrical test signals with specific parameters. These signals can simulate signals in actual circuits and are used in fields such as testing, research and development, repair, measurement, and calibration. They are the best tool for electronic engineers to conduct signal simulation experiments and play a vital role in electronic experiments and test processing.

[0003] The multi-band synthesized signal generation circuit module generates a lot of heat during operation. This is because the multi-band synthesized signal generation circuit module needs to generate and amplify high-frequency signals. These high-frequency signals will generate energy loss when transmitted in the circuit, which will be converted into heat. Therefore, a new multi-band synthesized signal generation circuit module needs to be designed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a multi-band synthesized signal generation circuit module to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a multi-band synthesized signal generation circuit module, including a substrate and pins. Several pins are fixedly connected to the edge of the substrate, and a clock module, a frequency control module, a waveform generation module, a modulation module, an output amplification module, and a control module are mounted on the substrate.

[0007] The control module is located in the center of the substrate, the clock module and the frequency control module are located on one side of the control module, and the waveform generation module, the modulation module and the output amplification module are located on the other side of the control module.

[0008] Through holes are formed at several points on the substrate, and heat sinks are installed in the through holes;

[0009] The bottom of the heat sink is fixedly connected to a chassis, and the bottom of the chassis is fixedly connected to a plurality of heat sinks, which are arranged in a circular array about the axis of the chassis.

[0010] An interface layer is attached to one or both sides of the clock module, frequency control module, waveform generation module, modulation module, output amplification module, and control module. A thermal pad is fixedly connected to the top of the heat sink.

[0011] Preferably, in any of the above embodiments, the substrate is divided into three layers: a top layer, a middle layer, and a heat dissipation layer, which are formed by hot pressing.

[0012] Using the above technical solution: the top layer can be a copper foil layer, the middle layer is an insulating layer, and the heat dissipation layer is an aluminum layer.

[0013] Preferably, in any of the above schemes, the stable clock signal generated by the clock module is input to the frequency control module, and the waveform generation module generates a corresponding signal waveform according to the waveform type and parameters selected by the user, and outputs it to the modulation module.

[0014] The above technical solution employs the following: A clock module provides a stable clock signal, which serves as the reference for the entire signal generator. The stability and accuracy of the clock signal directly affect the frequency and phase of the output signal. A frequency control module adjusts the clock signal frequency according to user-defined frequency parameters via a frequency synthesizer or frequency divider. The frequency synthesizer can be based on Direct Digital Synthesis (DDS) technology, generating waveform data through a digital signal processor to precisely control the frequency of the output signal. A waveform generation module is responsible for generating various types of signal waveforms, such as sine waves, square waves, and triangle waves. These waveforms can be generated using analog or digital circuits. In digital circuits, waveform generation is typically based on DDS technology, storing digital amplitude information of different waveforms in a waveform memory, and then accessing the waveform memory according to the output address of the phase accumulator to obtain the corresponding waveform amplitude value. A modulation module is used to modulate the signal to achieve different communication requirements. Modulation methods include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). The modulation module consists of a modulator and a demodulator. During modulation, the modulation module loads the baseband signal (i.e., the information signal to be transmitted) onto the carrier signal to form a modulated signal. The modulated signal is then amplified and output to external devices or systems. The output amplification module amplifies the generated signal waveform to an appropriate amplitude to meet the needs of different application scenarios. The output amplification module typically consists of a power amplifier and attenuator components.

[0015] Clock signal generation: First, the clock module generates a stable clock signal as the reference for the entire signal generator.

[0016] Frequency control: The frequency control module adjusts the frequency of the clock signal through a frequency synthesizer or frequency divider according to the frequency parameters set by the user.

[0017] Waveform generation: The waveform generation module generates corresponding signal waveforms based on DDS technology or analog circuits, according to the waveform type and parameters selected by the user.

[0018] Modulation processing: If signal modulation is required, the modulation module will modulate the amplitude, frequency or phase of the generated signal.

[0019] Output processing: Finally, the output amplification module amplifies the modulated signal waveform to an appropriate amplitude and outputs it to an external device or system through the output interface.

[0020] Preferably, in any of the above schemes, the output amplification module amplifies the modulated signal waveform to an appropriate amplitude and outputs it to an external device or system. The control module receives control commands input by the user and adjusts the gain and attenuation parameters of the output amplification module according to the commands. The clock module, frequency control module, waveform generation module, modulation module, output amplification module and control module transmit signals to each other via signal lines or buses.

Then, through-holes are made at several points on the substrate, and heat sinks are installed in the through-holes. The bottom of the heat sink is fixedly connected to the chassis, and several heat sinks are fixedly connected to the bottom of the chassis. The heat sinks are arranged in a circumferential array about the axis of the chassis. Then, a thermally conductive interface layer is attached to one or both sides of each module to conduct heat to the heat sink through the hot spot, and then achieve large-area heat dissipation through the numerous heat sinks at the bottom. Heat is quickly conducted from the top layer to the bottom heat dissipation layer, forming a composite structure of "vertical heat conduction column + radial heat dissipation fins", which realizes the efficient heat dissipation of this module. It is suitable for compact spaces and can achieve high heat flux density heat dissipation without the need for external large heat sinks. The circumferential distribution of the heat sinks evens out the temperature of the heat dissipation surface and avoids local overheating.

[0022] Preferably, in any of the above embodiments, the heat sink is bonded or welded to the inner wall of the through hole, and the heat sink is made of copper.

[0023] Preferably, the interface layer and the heating pad are copper foil layers, as described in any of the above schemes.

[0024] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
