10kw FM Combiner-Duplexer

Stability and reliability of multiplexer products   One. Features of FM multiplexer(Our FM multiplexer series products have the following characteristics.)1.Various structural forms.The basic structural units of FM multiplexers produced by our company include various structural forms, such as bridge type (constant impedance type), star type (star point type), delay type (phase sensitive type), improved bridge type, and hybrid structure composed of various basic units. At present, the design of FM multiplexer has been fully modularized. We can customize FM multiplexer products for users according to their different needs.2. Multiple power levels. Our company provides users with multiple power levels of FM duplexer units, including 1kW, 2kW, 3kW, 5kW, 10kW, 20kW, etc. The application of these unit modules can easily form various FM duplexers required by users.3. All indicators are excellent. Our company uses high-quality raw materials and advanced processing technology to produce FM multiplexers with excellent technical indicators. For example, the central frequency insertion loss of the FM duplexer FSCC200 applied to the 10kW power level is less than 0.15dB.4. The frequency is adjustable in full frequency band. At present, the working frequency of all FM multiplexers designed and produced by our company is adjustable in the full frequency band of 87~108MHz. If the user needs to change the frequency of the multiplexer, our engineers can complete the frequency change within 30 minutes without replacing any parts of the multiplexer after arriving at the user's site.5. Meet CDR standards. The FM multiplexers produced by our company have been optimized and designed. Except for some special products, the standard multiplexer products meet the requirements of the CDR standard and can realize the synthesis of CDR channels.6. The best synthesis scheme. Our company designs the optimal multiplexer synthesis scheme for users according to their different frequency and power requirements, taking into account their special requirements for multiplexer volume, scalability, project budget and other factors. The filters in the FM multiplexer include three cavity, three cavity band cross coupling, four cavity band cross coupling and other different structures, which can achieve channel synthesis with a minimum frequency interval of 0.4 MHz.7. Compact structure design. The structure of FM multiplexers produced by our company has been carefully designed and optimized to ensure the rationality of product layout, improve the space utilization rate as much as possible, and reduce the floor area and product weight.8. Special specification customization. According to the different needs of users, our company makes scientific analysis and fine design to tailor the FM multiplexer to meet the special needs of users.Two. Stability and reliability of FM multiplexer(For the following reasons, our FM multiplexer products have first-class stability and reliability.)1. Our company has strong R&D strength to ensure that multiplexer products have excellent stability and reliability at the beginning of design. All multiplexer products of the company, as well as various component-level products (such as filters, couplers, dummy loads, connecting accessories, etc.) that constitute multiplexers, must go through a strict computer simulation stage. On the premise of ensuring that the technical indicators of various products meet the design requirements, engineers will also focus on the distribution of electric and magnetic fields and heat dissipation of various products. We will accurately analyze the distribution of electric field and magnetic field in the product, find out the position where the electric field is the strongest and the most likely to occur, and make targeted modifications to the product structure, so that the product can achieve the maximum power capacity and improve the reliability of the product on the premise of ensuring excellent technical indicators. At the same time, the company's engineers will also simulate the heat dissipation of the product at work, the purpose of which is also to find the weak link in the heat dissipation of the product during the design process and focus on improving it. The following are the computer simulation results of some FM filters and 3dB couplers completed by our company. FM filters and 3dB couplers are the core components of FM multiplexers.Computer Simulation Results of Electric Field Distribution of 10kW FM Bandpass FilterComputer simulation results of heat dissipation of 10kW FM bandpass filterComputer Simulation Results of Electric Field Distribution of 50kW FM 3dB Coupler2. Experience and concept advantages. Our core team has nearly 20 years of experience in the development and production of radio and television passive equipment, and has produced more than 2000 sets of FM and TV multiplexers. The sales of multiplexer products cover all provinces, autonomous regions and municipalities dire
