Description

Technical Field

[0001] This utility model relates to the field of microwave communication, and in particular to a multi-channel 26-30G frequency conversion component. Background Technology

[0002] In the field of microwave communication, the demand for multi-channel frequency converters in the 26-30 GHz band is growing rapidly. However, existing technologies, when processing signals in this band, face several challenges. First, they struggle to achieve synchronous processing of multiple signals, failing to guarantee the consistency of amplitude and phase between signals. This leads to signal interference and degraded communication quality, failing to meet the stringent requirements for signal synchronization in high-precision communication scenarios (such as 5G millimeter-wave communication testing and advanced radar systems). Second, they lack effective miniaturization and modular design solutions. Traditional components are complex in structure and have low integration, making it difficult to independently manufacture and debug each functional module during production. This not only increases the complexity of the production process and reduces production efficiency but also hinders subsequent maintenance, upgrades, and mass application, failing to meet the demands of modern communication equipment for compact space and flexible assembly. Therefore, a new multi-channel 26-30 GHz frequency converter is urgently needed to solve these technical problems and improve the performance and practicality of frequency band signal processing. Utility Model Content

[0003] The purpose of this invention is to provide a multi-channel 26-30G frequency converter with consistent amplitude and phase.

[0004] The purpose of this utility model is achieved as follows: a multi-channel 26-30G frequency converter component includes four identical single-channel standard components, a metal cavity plate, and a local oscillator module. The four identical single-channel standard components are fixed on the metal cavity plate by an assembly structure. Each single-channel standard component includes a primary filter module, a mixer module, and a secondary filter module connected in series. The local oscillator module is connected to the mixer module in the four single-channel standard components through a power divider.

[0005] Preferably, the primary filtering module is a 26-30G filter and a first low-noise amplifier connected in series, and the output frequency of the primary filtering module is 26-30G.

[0006] Preferably, the mixing module is a mixer and a 3-5GHz filter connected in series, and the output frequency of the mixing module is 3-5GHz.

[0007] Preferably, the secondary filtering module is a second low-noise amplifier, a third low-noise amplifier, and a 3-5GHz filter connected in series, and the output frequency of the secondary filtering module is 3-5GHz.

[0008] Preferably, the local oscillator module is a temperature-controlled crystal oscillator that outputs 23-25GHz and then outputs four local oscillator signals through a 1-to-4 power divider. The four local oscillator signals are then mixed with a 26-30GHz frequency by a mixer before being output.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. By designing the single-channel signal processing path as a standard component and assembling it into the entire frequency conversion assembly, this utility model can ensure the amplitude and phase consistency of the four input and output signals, meeting the requirements of high-precision signal processing.

[0011] 2. This utility model adopts a modular design, which decomposes the frequency converter into multiple standard parts that can be produced and tested independently. This not only simplifies the production process but also improves production efficiency and facilitates mass production and quality control. Attached Figure Description

[0013] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0014] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0015] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1 As shown, a multi-channel 26-30G frequency converter includes four identical single-channel standard components, a metal cavity board, and a local oscillator module. The four identical single-channel standard components are fixed to the metal cavity board by an assembly structure. Each single-channel standard component includes a primary filter module, a mixer module, and a secondary filter module connected in series. The local oscillator module is connected to the mixer module in the four single-channel standard components through a power divider. The single-channel signal processing path is designed as a standard component to ensure the amplitude and phase consistency of the four input and output signals. The entire frequency converter is constructed by assembling multiple standard components to physically ensure the consistency between each channel. After assembly, each component is debugged individually to ensure that the overall performance meets the requirements.

[0017] The primary filtering module consists of a 26-30G filter and a first low-noise amplifier connected in series. The primary filtering module outputs a frequency of 26-30G. The 26-30G filter removes out-of-band interference signals. Subsequently, the first low-noise amplifier amplifies the filtered signal, increasing the signal power to a suitable level, thus laying the foundation for subsequent mixing processing.

[0018] The mixing module consists of a mixer and a 3-5GHz filter connected in series. The output frequency of the mixing module is 3-5GHz. The filter removes out-of-band spurious signals to ensure the spectral purity of the output 3-5GHz intermediate frequency signal and meet the spurious and harmonic index requirements.

[0019] The secondary filtering module consists of a second low-noise amplifier, a third low-noise amplifier, and a 3-5GHz filter connected in series, with an output frequency of 3-5GHz. The signal power is first increased by two stages of low-noise amplifiers; then, it undergoes secondary filtering by the 3-5GHz filter to further suppress residual spurious signals and noise, ensuring that the signal's in-band fluctuation, linear dynamic range, and other indicators meet the requirements, ultimately outputting a compliant 3-5GHz radio frequency signal.

[0020] The local oscillator module outputs a 23-25GHz temperature-controlled crystal oscillator. It then uses a 1-to-4 power divider to output four local oscillator signals. These four local oscillator signals are mixed with a 26-30GHz frequency by a mixer before being output.

[0021] The specific specifications of this utility model are as follows:

[0022] a) Input signal frequency: 26–30 GHz;

[0023] b) Number of input signals: 4;

[0024] c) Input RF signal power: -70~-30dBm;
