![]() For economical reasons the components have been engineered for these different frequency bands. ![]() Phase Adjusters are available for different frequency ranges (DC - 2.0 GHz, DC - 12.4 GHz, DC - 18.0 GHz, DC - 26.5 GHz, DC - 40.0 GHz, DC - 50.0 GHz and DC - 65.0 GHz). The designs of Spectrum Elektrotechnik GmbH employs air lines, whenever possible. Using an air line results in low insertion loss and good VSWR. For higher frequencies or shorter adjustments, only a straight line may be sufficient. For lower frequencies or longer phase adjustments, a trombone line is usually used. The phase shifters are mechanical devices, therefore the change of phase depends on the adjustment of the elctrical length of a line. A wide selection of components is available, offering different mechanical configuration, frequency range, electrical length and/or connector configuration. A secure locking mechanism is furnished with every unit. ![]() A precision mechanical movement provides for smooth and accurate adjustment over the entire frequency range. The Precision Phase Shifters - or Phase Adjusters - allow the adjustment of the electrical separation between components.
