Description
N Type High Power Termination Load Jack (Female) | DC to 4 GHz | 50 Ω | 300 W
The ROSNOL T-N25-4G300WA/H3 is an ultra-high-power N Type termination load jack engineered for RF systems requiring substantial power dissipation up to 4 GHz. Supporting a 50 Ω impedance and a frequency range from DC to 4 GHz, it provides a maximum VSWR of ≤ 1.40 (Return Loss ≥ 15.56 dB). With an average power rating of 300 W at 25°C, this termination load is designed for terminating high-power transmitters, power amplifiers, and system outputs in telecommunications, industrial RF, and broadcast transmitter environments. The screw-lock coupling mechanism ensures stable installation under high thermal and mechanical loads.The center contact is manufactured from phosphor bronze with gold plating to ensure stable conductivity under high-current operation. The connector body is made of brass with nickel plating to deliver excellent mechanical strength and corrosion resistance. A PTFE insulator maintains consistent dielectric performance, while the large aluminum heat sink with black anodized surface is optimized for efficient thermal dissipation during continuous high-power operation. The reinforced mechanical design supports long-term reliability in high-power RF environments.
ROSNOL ultra-high-power RF termination loads are produced under ISO 9001-certified quality management systems and comply with RoHS and REACH requirements. Offering exceptional power handling capability, dependable RF performance, and competitive cost efficiency, ROSNOL termination loads provide reliable alternatives to established European and American RF component manufacturers. Comprehensive customization services are available to support specialized RF and microwave system requirements.
