Description & Specification
2.92mm Precision Adapter
DC to 40 GHz | VSWR ≤ 1.20 | Model: 2.92-JJG
The 2.92-JJG is a high-performance coaxial adapter featuring a precision 2.92mm (K-type) interface layout, professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for millimeter-wave applications. Operating across an ultra-wide spectrum from DC to 40 GHz, this instrumentation-grade component guarantees exceptional signal integrity with an industry-leading maximum V.S.W.R profile of ≤ 1.20 : 1. Designed for high-frequency repeatability, its rugged air-dielectric core setup provides mode-free operation while ensuring mechanical compatibility with standard SMA and 3.5mm interfaces. Built from premium structural materials in Taiwan, it thrives under strict thermal limits from -55°C up to +165°C, making it a critical asset for 5G millimeter-wave infrastructures, satellite communication networks, aerospace systems, and high-fidelity lab setups.
