Description

Technical Field

[0001] This utility model relates to the field of microwave communication, and in particular to a 1-40GHz upconversion component. Background Technology

[0002] In the fields of electronic systems such as communications and radar, upconversion modules play an important role in converting signal frequencies to the required frequency bands to meet the signal frequency requirements of different application scenarios.

[0003] Traditionally, frequency converter modules have a single channel design, capable of outputting only one or a few fixed frequency band signals, making it difficult to process multi-frequency band signals simultaneously. In complex systems, different devices have diverse frequency band requirements, and a single frequency band output cannot meet the diverse application needs, resulting in limited system functionality and inability to fully utilize performance. Furthermore, traditional module signal processing links are simple in design, with insufficient precision in filtering, mixing, and amplification, making it difficult to effectively filter out stray signals and ensure the accuracy of the output signal frequency and the stability of power. Signal quality is degraded during processing, affecting the overall system performance. Utility Model Content

[0004] The purpose of this invention is to provide a 1-40GHz upconversion component with multi-channel output and stable operation.

[0005] The purpose of this utility model is achieved as follows: A 1-40GHz upconversion component includes a main channel and three sets of output channels; the three sets of output channels are respectively a 1-6GHz output channel, a 6-18GHz output channel, and a 33-40GHz output channel; the main channel is composed of a 1.75-1.85G filter, a first mixer, a 4.95-5.05G filter, a first amplifier, a first programmable controller, a second mixer, a second amplifier, a switch group, a second programmable controller, and a third amplifier connected in series; the output terminal of the main channel outputs as a 1-6GHz output channel, a 6-18GHz output channel, and a 33-40GHz output channel respectively through a single-pole triple-throw switch.

[0006] Preferably, the 1-6GHz output channel consists of a 13-18G filter, a third mixer, a 1-6G filter, a third programmable controller, a fourth amplifier, a fourth programmable controller, a fifth amplifier, a fifth programmable controller, a sixth amplifier, a first filter, and a first coupling connected in series.

[0007] Preferably, the 6-18GHz output channel consists of a sixth programmable controller, a seventh amplifier, a seventh programmable controller, an eighth amplifier, a second filter, and a second coupling connected in series.

[0008] Preferably, the 33-40GHz output channel consists of a 6.5-10G filter, a fourth mixer, a 33-40G filter, an eighth programmable controller, a ninth amplifier, a ninth programmable controller, a tenth amplifier, a tenth programmable controller, an eleventh amplifier, a third filter, and a third coupling connected in series.

[0009] Preferably, the first mixer is mixed with a 6.8G local oscillator, the second mixer is mixed with an 11-26G local oscillator, the third mixer is mixed with an 18G local oscillator, and the fourth mixer is mixed with a 26.5 / 30G local oscillator.

[0010] Preferably, the switch group consists of a two-stage single-pole four-throw switch, a 6-9G filter, a 9-12G filter, a 12-15G filter, and a 15-18G filter. The signal is output in four paths after passing through the single-pole four-throw switch. After passing through the 6-9G filter, the 9-12G filter, the 12-15G filter, and the 15-18G filter, the signal is divided into four frequency segments, which are then combined into one signal output by the single-pole four-throw switch.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. Equipped with three output channels: 1-6GHz, 6-18GHz, and 33-40GHz, enabling multiple channels to work simultaneously; the multi-channel design of this module can process signals of different frequency bands at the same time, improving system efficiency and flexibility, and meeting diverse application needs.

[0013] 2. In the main channel, the signal undergoes filtering, mixing, and amplification processes sequentially. Through precise frequency conversion and signal amplification, stray signals are effectively filtered out, ensuring the frequency accuracy and power stability of the output signal. Each output channel is also specifically designed according to the characteristics of different frequency bands to ensure that the signal quality is not compromised during processing.

[0014] 3. By rationally selecting the local oscillator frequency, precise up-conversion of the signal can be achieved, improving the frequency conversion efficiency and output signal quality of the system, and meeting the requirements of high-precision, high-performance communication and radar systems.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 As shown, a 1-40GHz upconversion component includes a main channel and three output channels; the three output channels are a 1-6GHz output channel, a 6-18GHz output channel, and a 33-40GHz output channel, respectively; the main channel is composed of a 1.75-1.85G filter, a first mixer, a 4.95-5.05G filter, a first amplifier, a first programmable controller, a second mixer, a second amplifier, a switch group, a second programmable controller, and a third amplifier connected in series; the output of the main channel is output as a 1-6GHz output channel, a 6-18GHz output channel, and a 33-40GHz output channel respectively through a single-pole triple-throw switch.

[0020] The 1-6GHz output channel consists of a 13-18G filter, a third mixer, a 1-6G filter, a third programmable controller, a fourth amplifier, a fourth programmable controller, a fifth amplifier, a fifth programmable controller, a sixth amplifier, a first filter, and a first coupling connected in series.

[0021] The 6-18GHz output channel consists of the sixth programmable controller, the seventh amplifier, the seventh programmable controller, the eighth amplifier, the second filter, and the second coupling connected in series.

[0022] The 33-40GHz output channel consists of a 6.5-10G filter, a fourth mixer, a 33-40G filter, an eighth programmable controller, a ninth amplifier, a ninth programmable controller, a tenth amplifier, a tenth programmable controller, an eleventh amplifier, a third filter, and a third coupling connected in series.

[0023] The aforementioned multiple programmable amplifiers can precisely adjust and enhance parameters such as signal amplitude and phase according to actual needs, while the first filter and the first coupling ensure the quality and stability of the output signal.

[0024] The first mixer mixes with a 6.8GHz local oscillator, the second mixer mixes with an 11-26GHz local oscillator, the third mixer mixes with an 18GHz local oscillator, and the fourth mixer mixes with a 26.5 / 30GHz local oscillator. By appropriately selecting the local oscillator frequency, precise up-conversion of the signal is achieved, converting the input signal to the required output frequency band, improving the system's frequency conversion efficiency and output signal quality, and meeting the frequency requirements of different frequency band output channels.

[0025] The switch group consists of a two-stage single-pole four-throw switch, a 6-9G filter, a 9-12G filter, a 12-15G filter, and a 15-18G filter. The signal is output in four paths after passing through the single-pole four-throw switch. After passing through the 6-9G filter, the 9-12G filter, the 12-15G filter, and the 15-18G filter, the signal is divided into four frequency segments and then combined into one signal output by the single-pole four-throw switch.

[0026] The working principle of this utility model is explained as follows:

[0027] The input signal first enters the main channel, where it undergoes initial filtering of spurious signals by a 1.75-1.85GHz filter. It is then mixed with a 6.8GHz local oscillator in the first mixer for initial frequency conversion, followed by further purification through a 4.95-5.05GHz filter. The first amplifier amplifies the signal appropriately to meet subsequent processing requirements. The signal then sequentially passes through the first programmable controller, the second mixer (mixed with an 11-26GHz local oscillator), and the second amplifier before entering the switching group. The switching group consists of two stages of single-pole four-throw switches and multiple filters. It outputs the signal in four paths, which are then segmented by filters at 6-9GHz, 9-12GHz, 12-15GHz, and 15-18GHz respectively. These segments are then combined into a single signal, which passes through the second programmable controller and the third amplifier before being distributed to different output channels via a single-pole three-throw switch.

[0028] For the 1-6GHz output channel, the signal is first processed by a 13-18GHz filter, then mixed with an 18GHz local oscillator in the third mixer to convert to the target frequency band. After precise filtering by the 1-6GHz filter, the signal parameters are adjusted by multiple programmable controllers and amplifiers, and finally output after the first filter and first coupling. In the 6-18GHz output channel, the signal is sequentially processed by the sixth programmable controller, the seventh amplifier, the seventh programmable controller, and the eighth amplifier, then output after the second filter and second coupling. In the 33-40GHz output channel, the signal is processed by a 6.5-10GHz filter, then mixed with a 26.5 / 30GHz local oscillator in the fourth mixer to convert to the high-frequency band. After precise filtering by the 33-40GHz filter, the signal is enhanced by multiple programmable controllers and amplifiers, and finally output after the third filter and third coupling. This achieves efficient and precise signal processing from input to multi-band output.

[0029] The actual specifications of this utility model are as follows: a) Input frequency range: 1.75~1.85GHz; b) Output frequency range: 1-18GHz (can be divided into 1-2GHz, 2-6GHz and 6-18GHz), 33-40GHz; c) Input power: -20dBm; d) Input filter suppression: ≥42dBc@≤1.65GHz&≥1.95GHz; e) Output power: 18±3dBm (direct output path); coupled output path, power -10±5dBm; f) Output power fluctuation: ≤±1.5dB (within any 100MHz band) ≤±3dB, where the 1-18GHz band is divided into 1-2GHz, 2-6GHz and 6-18GHz for separate testing; h) In-band spurious emissions: ≤-45dBc (tested in both pulse wave and continuous wave modes, with in-band spurious emissions level ≤-30dBm when there is no signal input); i) Out-of-band rejection: ≥42dBc (tested without harmonics, in both pulse wave and continuous wave modes, with out-of-band spurious emissions level ≤-27dBm when there is no signal input).
