The 2W SMA Attenuator is a fixed RF component designed for signal management in applications spanning DC to 18 GHz, with attenuation levels adjustable from 1 to 30 dB. It features a nominal impedance of 50 ohms, ensuring compatibility with standard RF systems, and a maximum average power rating of 2 watts. The VSWR of 1.20 minimizes reflection loss, making it suitable for high-frequency environments where signal integrity is critical.
This attenuator is constructed with SMA connectors, a standard interface for RF equipment, and is built to withstand industrial temperature ranges. Typical attenuators in this category use resistive elements with thin-film technology for precision and stability across the frequency spectrum. The compact design allows for easy integration into test benches, telecommunications equipment and broadcasting systems.
Buyers in telecommunications, broadcasting and testing laboratories source these attenuators for signal level adjustment, impedance matching and system calibration. The component is particularly useful in scenarios where signal strength must be reduced without distorting the waveform. Trade terms such as MOQ, packaging and incoterms are not specified in the listing and should be confirmed directly with Yicheng Technology.

Yicheng Technology Co., Ltd. is located in the Baotian Industrial Zone, Shenzhen, Guangdong Province, China. The company operates as an imported-tier supplier specializing in RF and microwave components, including attenuators, connectors and adapters. Shenzhen is a major hub for electronics manufacturing, providing access to advanced production facilities and supply chains.
The supplier’s profile indicates a harbor trust tier, with a current response rate of 0.00% and no recorded average response time. This suggests that buyers may need to proactively follow up on inquiries. The listing does not provide details on certifications, production capacity or client references, so these should be requested directly to assess the supplier’s reliability and quality control processes.

Before ordering, confirm the exact frequency range and attenuation values required for your application, as the 2W SMA Attenuator covers DC to 18 GHz but may not be suitable for all sub-ranges. Request the supplier’s datasheet to verify the attenuator’s performance at your specific frequencies, particularly at the upper end of the range where insertion loss and VSWR can degrade. Ensure the connector type (SMA male/female) matches your system’s requirements to avoid compatibility issues.
Discuss logistics terms with Yicheng Technology, including the Incoterms (e.g., FOB Shenzhen), packaging method (e.g., anti-static bags, foam inserts) and lead time for production and shipping. RF components are sensitive to electrostatic discharge (ESD), so confirm that the packaging provides adequate protection. For large orders, ask about bulk packaging options and any discounts for volume purchases.
Perform quality checks upon receipt, including visual inspections for physical damage, connector integrity and proper labeling. Use a vector network analyzer (VNA) to test the attenuator’s performance across your frequency range, verifying attenuation accuracy, VSWR and insertion loss. Request all relevant documentation, such as calibration certificates, material datasheets and compliance certifications, to ensure the product meets your technical and regulatory requirements.
