What is the indoor distribution system? Indoor distribution system is used to cover the indoor blind area of the system, the signal into the indoor through indoor installation of antennas, feeders, power dividers, couplers and other devices to achieve the purpose of coverage Indoor distribution system is a successful scheme for indoor user groups to improve the mobile communication environment in ...

In wireless communications, radar systems, RF testing, and other fields, the directional coupler stands as a critical passive component, enabling unique signal separation and monitoring capabilities that make it indispensable in modern electronic systems. This article delves into the working principles, core advantages, and real-world applications of directional couplers across industrie...

The radio on the airplane is generated by radio signals transmitted through radio transmitters (beacon stations). These signals assist the aircraft in navigation and communication. The Application of Radio in Aircraft Aviation radio communication: including satellite communication, very high frequency ground to air communication, etc., providing various voice communication, radar signal connection...

In RF and microwave systems, power distribution is a critical aspect that directly impacts system performance, reliability, and design flexibility. Two of the most commonly used passive components for signal splitting and power monitoring are directional couplers and tappers. While they serve similar purposes in many systems, they differ significantly in structure, application, and performance. Un...

In RF and microwave systems, signal routing, splitting, and combining require high-precision components that minimize losses and distortion. One such essential component is the hybrid coupler. But why use a hybrid coupler instead of standard power dividers or directional couplers? This article explores the purpose, benefits, and applications of hybrid couplers—especially in systems where signal ph...

In the world of wireless communications, signal integrity and system protection are paramount. An RF attenuator plays a crucial role in both areas. Whether you’re working in a lab environment, designing a base station, or setting up an indoor DAS system, RF attenuators help manage signal strength and ensure long-term reliability. What Is an RF Attenuator? An RF attenuator is a passive component de...

In RF and microwave communication systems, precise control over signal strength is critical. A coaxial variable attenuator is a key component used to adjust the amplitude of RF signals without distorting the waveform. Whether you're testing signal paths, protecting sensitive equipment, or balancing signal levels in a network, variable attenuators offer both flexibility and accuracy. What Is a Coax...
