High Power, High Frequency Terminators Wraparound termination with non-leaching Nickel barrier PCS-R Series • Single sided flange style • Up to 12.5W power dissipation • High frequency operation to 2.1GHz Ultra stable Tantalum Nitride resistor film system The PCS-R series high power thin film terminator is designed for termination of RF signals as a surface mount coupler load or other RF applications. Typical applications include high power RF amplifiers, and wireless base stations. Higher power dissipation is achieved by attaching a wrap-around flange directly to the heat sink. The thin film construction provides consistent operational stability over temperature and time.
