OSTI ID:10176171
A resistive match has been developed as part of the measurement setup to determine the longitudinal coupling impedance of RHIC devices. Even though various calibration techniques have been implemented the broadband resistive match provides a smooth transition from the 50 {Omega} impedance of the HP8753C Network Analyzer to the 188 {Omega} characteristic impedance of the setup and can allow for valid measurements with a simple through reference calibration. The match has been tested for accuracy using both a narrowband quarterwave cavity and a broadband prototype bellow. In both cases an analytical approximation could be used together with a computer model to check the measured results. The errors in the calibrated measurement method have been tested to be less than 10% for frequencies up to 2 GHz.
