The MST981B35 is a manual slide screw tuner for impedance matching, designed for device characterization and power transfer optimization. It features a dual probe structure with a 3.5 mm precision connector and operates from 0.4 to 4.0 GHz, achieving a maximum VSWR matching range of 25:1. The tuner includes an LCD readout for carriage position and has a maximum insertion loss of 0.2 dB. The probe crossover frequency is 1.4 GHz, and the unit has a physical length of 14.75 inches (37.47 cm). It supports power handling of 250 watts average and 2500 watts peak within its matching range.
Based on precision slide screw technology, Maury’s manual tuners offers great positional repeatability with its LCD readout for carriage position and high matching range utilizing two probes to maintain performance across the band. Our manual tuners are ideal for use as a variable impedance source for applications such as device characterization or for maximizing power transfer between a generator and a load.
