Maury Microwave 1643M Slide Screw Tuner, 0.8 to 18 GHz, Type N
The Maury 1643M Coaxial Slide Screw Tuner provides a convenient method of matching a wide range of impedances to a 50 ohm transmission line system. The 1643 Tuner consists of a coaxial slot line section with a sliding carriage upon which two adjustable micrometers are mounted. The .001 inch reading micrometer controls a variable reactance element whose magnitude is changed by varying its depth of insertion into the coaxial line and whose phase is varied by sliding the carriage along the line. Carriage travel is greater than one-half wavelength at the lowest operating frequency. A metric scale and vernier is provided to give precise readout of the carriage position to within 1/10 millimeter. Position locks are provided on both micrometer and the carriage. The double probe tuner utilizes two variable reactance elements to achieve an extremely high matching capability over a broad frequency range. In normal operation, only one probe is required to match an impedance having a VSWR of 6:1 or less. Both probes are required only at the lowest frequencies, as much higher VSWR's can generally be matched over most of the operating band. The Maury 1643M Tuner employs precision stainless steel type N female and male connectors. Specifications of the Maury 1643 series of Tuners includes: Frequency Range 0.8 - 18 GHz Insertion Loss (Dissipative) 0.75 dB Max, <0.5 dB typ. Max VSWR with Probe Out: 1.15 Max Nominal Impedance: 50 Ohm Travel at Lowest Frequency: 1/2 Wavelength Minimum Matching Range: 6:1 Minimum Power Handling: CW: 50W Peak: 0.5kW
