Abstract
A reflectionless termination design is described which, in principle, can be adapted to wave-guide or coaxial transmission lines. Reflection coefficients of 0.001 were obtained experimentally with X-band wave-guide terminations. The termination comprises a section of transmission line into which is fitted a tunable sliding load. The sliding load is tuned to be reflectionless by means of the ``sliding load'' method of measuring reflection coefficients. The termination can be operated over a wide frequency range but must be retuned each time the frequency is changed. The wave-guide circuit of the load is analyzed and design equations are derived. The reflectionless wave-guide termination is primarily useful as a reference standard for microwave impedance bridges.Keywords
