جودة وحدة تشويش الإشارة & الـ (PCB) المضطرب للإشارة الصانع

The data processing circuit consists of AD digital to analog conversion ADC0809, AT89C51 microcontroller, and display circuit. ADC0809 is an eight bit eight channel single-chip AD successive approximation converter made using CMOS technology. The successive approximation converter includes one comparator, one digital to analog conversion controller, one successive approximation register (SAR), and one logic control unit. The successive approximation in the conversion is controlled by the logic unit according to the principle of division. Its principle is simple, easy to implement, and there is no delay problem. AT89C51 is a high-performance 8-bit microcontroller with 4K bytes of FLASH programmable erasable read-only memory. Its instruction system is fully compatible with MCS-51, making it easy to apply in various control fields. In the design, P0 port serves as the data port, P1 port serves as the switch input/output control, P2 serves as the display module and address control line for ADC0809, and the IN terminal serves as the keyboard interrupt input terminal, thus forming a simple microcontroller measurement system. The voltage signal after LM331F/conversion is sent to ADC0809 for digital to analog conversion. The AT89C51 microcontroller reads the converted data in real time, calculates it through internal software, and sends the results to the display screen for display. The displayed content mainly includes the current of each power amplifier tube, power supply voltage, output power, and reflected power. The input switch detection signal is directly sent to the P1 port of AT89C5 after photoelectric isolation. The display circuit adopts a 16x2 character dot matrix LCD display module, which has 192 built-in characters (5x7 dot font), strong indication function, can form various input, display and shift modes, and has the characteristics of simple interface with MCS-51 series microcontrollers and simple software programming.

In today's world, wireless threats are constantly evolving. A static, single-purpose jamming system may have been enough in the past, but with a growing number of communication frequencies and new technologies, adaptability is key. So, how can you ensure your jamming system is ready to face modern threats and future-proof your security? The answer lies in the core of your system: the Signal Jammer Module. A Signal Jammer Module is a modular, high-performance component designed to generate specific jamming signals. It is the building block that allows for a truly flexible and scalable solution. Our modules provide the adaptability you need for several reasons: Frequency Agility: Each module is designed to target a specific frequency band, such as 2G/3G/4G, Wi-Fi, Bluetooth, or GPS. By selecting and integrating different modules, you can create a custom jammer that addresses a wide range of threats simultaneously. Scalability: The power and range of your jamming system can be easily adjusted. You can start with a few modules for a small, portable jammer and add more to cover a larger area, all without replacing the entire unit. Rapid Deployment: When a new threat emerges, you don't need to redesign your entire system. Our modular design allows you to quickly integrate a new module to counter the new frequency, ensuring your security is always up-to-date. By choosing our Signal Jammer Module, you're not just buying a component; you're investing in a future-ready, adaptable, and professional-grade security solution.

تردد التشغيل لمضخمات القدرة RF مرتفع جدًا، لكن النطاق الترددي ضيق نسبيًا. تستخدم مضخمات القدرة RF بشكل عام شبكة اختيار التردد كدائرة القطع السلبية. يمكن تصنيف مضخمات القدرة RF إلى ثلاث حالات عمل: A و B و C وفقًا لزوايا التوصيل المختلفة للتيار. زاوية التوصيل لتيار مضخم الفئة A هي 360 درجة، وهي مناسبة لتضخيم الإشارات الصغيرة منخفضة الطاقة. زاوية التوصيل لتيار مضخم الفئة B تساوي 180 درجة، بينما زاوية التوصيل لتيار مضخم الفئة C أقل من 180 درجة. كل من الفئة B والفئة C مناسبتان لظروف العمل عالية الطاقة، حيث تتمتع الفئة C بأعلى قدرة إخراج وكفاءة بين حالات العمل الثلاث. تعمل معظم مضخمات القدرة RF في الفئة C، ولكن تشويه شكل موجة التيار لمضخمات الفئة C كبير جدًا ولا يمكن استخدامه إلا لتضخيم القدرة الرنانة للحمل باستخدام الدوائر المضبوطة. نظرًا لقدرة الترشيح لدائرة الضبط، لا يزال التيار والجهد في الدائرة يقتربان من شكل موجة جيبية بأقل قدر من التشوه.
