Spectrum Elektrotechnik GmbH offers a new line of Miniature Phase Adjusters, operating in the frequency range DC - 40.0 GHz (2.92 mm), DC - 50.0 GHz (2.4 mm) and DC - 63.0 GHz (1.85 mm). The products, as the standard units, which start at 2.0 GHz, are designed for constant impedance of 50 Ohms over the whole adjustment range. The precision mechanical mechanism guarantees continuous adjustment over the entire frequency range, and a locking mechanism ensures stability of the desired position during vibration.
