N Plug (Male) Termination Load, DC-4GHz 25W VSWR 1.15

N Type Termination Load Plug (Male) | DC to 4 GHz | 50 Ω | 25 W

The ROSNOL T-N15-4G25WA/144 is a high-power N Type termination load plug developed for RF systems requiring higher power dissipation up to 4 GHz. Featuring a nominal impedance of 50 Ω and a frequency range from DC to 4 GHz, it delivers a maximum VSWR of ≤ 1.15 (Return Loss ≥ 23.13 dB), ensuring excellent impedance matching across the operating band. Rated for 25 W average power handling at 25°C, this termination load is suitable for terminating RF transmitter outputs, power amplifier ports, and test equipment interfaces in telecommunications infrastructure and RF measurement systems. The screw-lock coupling mechanism ensures secure attachment under operating conditions.

The center contact is manufactured from brass with gold plating over a nickel underlayer to provide low contact resistance and stable performance at elevated power levels. The connector body is constructed from brass with a copper–tin–zinc alloy finish, offering durability and corrosion resistance. An integrated aluminum heat sink with black anodized coating enhances thermal dissipation during continuous operation. The PTFE insulator maintains reliable dielectric performance. This mechanical configuration supports long-term stability in high-power RF environments.

ROSNOL high-power RF termination loads are produced in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Designed to deliver reliable RF performance, effective thermal management, and competitive cost efficiency, ROSNOL termination loads provide practical alternatives to leading European and American RF component manufacturers. Customization services for power handling, materials, plating, and mechanical design are available to support specialized RF and microwave system requirements.
