Wide-Band Microwave Transmission Measuring System |
| |
Abstract: | A relatively broad-band balanced microwave measurement system has been built using a traveling-wave tube amplifier which permits automatic phase and amplitude transmission measurements to be made simultaneously as a function of frequency over the frequency range 8.7 kmc-9.6 kmc. A phase accuracy of +-1 degree can be achieved for a change of attenuation in the unknown of 24 db. Loss measurements can be made with an accuracy of +-2 per cent. The bridge is built largely of commercially available components and can be easily duplicated. The basic technique is compatible with additional broad-banding efforts as improved components become available, and it will eventually be applicable to all microwave frequencies. |
