ROHO CONNECTOR LIMITED

    The relentless growth of 5G and the impending dawn of 6G are pushing radio frequency (RF) infrastructure to its limits. In this high-stakes environment, a specific component is gaining prominence for enabling denser, more efficient, and powerful networks: the 4.3-10 Attenuator. Industry leaders like ROHO are at the forefront, driving adoption with a class of fixed attenuators engineered for superior performance in congested signal paths. Classification: Defined by Robustness and Application     Unlike consumer-facing tech, attenuators are often classified by their connector interface and core functionality. The 4.3-10 series stands out as a specialized category designed to meet modern demands. Connector Interface: The name "4.3-10" itself is a key differentiator. It refers to a compact, lightweight connector interface that offers a superior alternative to traditional 7/16 types, allowing for higher port density in cellular base stations and other space-constrained infrastructure . Fixed Attenuation Design: Currently, the 4.3-10 attenuators available on the market are predominantly Fixed Attenuators . This means they provide a single, precise value of signal loss, which is crucial for consistently and predictably setting signal levels in a circuit. Models are available in standard attenuation values such as 3 dB and 10 dB . Panel Mount Construction: Engineered for robust infrastructure deployment, these attenuators feature a panel mount design . This ensures a secure and stable physical connection, vital for withstanding environmental stress and vibration in outdoor or industrial settings.     Performance Characteristics: Built for Power and Precision     The performance profile of 4.3-10 attenuators is tailored for high-power, broadband applications. Key parameters from datasheets highlight their capabilities: Broad Frequency Operation: These components support a wide frequency range, typically from as low as 100 MHz up to 6000 MHz (6 GHz) . This broad spectrum coverage makes them suitable for a vast array of applications, from legacy systems to modern 5G bands. Excellent Impedance Matching: A critical parameter for any RF component is the Voltage Standing Wave Ratio (VSWR). A low VSWR indicates good impedance matching and minimal signal reflection. 4.3-10 attenuators maintain a maximum VSWR of 1.4, ensuring efficient power transfer and signal integrity across their operating band . High Power Handling: A standout feature is their ability to handle significant RF power. With a characteristic impedance of 50 Ω—the standard for most communication systems—these attenuators can manage continuous wave (CW) input power levels exceeding 50 dBm (approximately 100 watts) in some high-power models . This high power tolerance is essential for transmitter stages and power amplifier conditioning. Ruggedized for Har...

    In an era of advancing 5G networks, satellite communication, and industrial IoT, the demand for reliable and durable RF components is higher than ever. Among these, the N-Type attenuator continues to be a preferred choice for engineers requiring performance in demanding environments. Today, we break down the classifications and key performance characteristics that make this component a perennial industry workhorse.     The N-Type connector, invented in the 1940s, set a standard for durability with its threaded coupling mechanism and characteristic 50-ohm impedance. N-Type attenuators built upon this foundation, offering a robust solution for reducing signal power (attenuation) with minimal distortion. Their ability to handle higher power levels and their superior weatherproofing make them indispensable in telecommunications infrastructure, military and aerospace applications, and high-power test setups.     N-Type attenuators are primarily classified based on their functionality and power handling capabilities:     1. Fixed Attenuators: These are the most common type, designed to provide a single, precise value of signal loss (e.g., 3 dB, 10 dB, 20 dB). They are valued for their simplicity, excellent electrical performance, and reliability. Fixed attenuators are further segmented by their power ratings, from small-signal benchtop models to high-power units capable of handling hundreds of watts.     2. Variable Attenuators: This category offers adjustable attenuation levels. Manual Step Attenuators: These devices allow users to select from a set of precise attenuation values using a rotary switch. They are critical in laboratory settings for calibration and testing, offering exceptional accuracy and repeatability. Continuously Variable Attenuators: These provide smooth adjustment over a specified range (e.g., 0-20 dB), allowing for fine-tuning of signal levels in circuit design and optimization.     3. DC Blocking vs. DC Passing: A crucial design distinction. Some N-Type attenuators are engineered to block DC bias voltages from passing through, protecting sensitive equipment. Others are designed to allow DC current to pass alongside the RF signal, which is essential for certain antenna systems like those used in GPS.     When specifying an N-Type attenuator, engineers focus on several critical parameters: High Power Handling: This is the standout feature of N-Type attenuators. They are routinely available in models that can handle average power levels from 2 Watts to over 100 Watts, and some specialized units can manage kilowatts of power, making them ideal for transmitter sites. Frequency Range: While excellent for applications up to 11 GHz, precision N-Type designs perform reliably up to 18 GHz, covering most cellular and C-band satellite frequencies. Low VSWR (Voltage Standing Wave Ratio): High-quality N-Type attenuators maintain a ...
