The 1819A is a triple-stub coaxial tuner designed for impedance matching in RF and microwave systems, operating from 0.4 to 1.0 GHz. It features SMA connectors and a maximum stub travel of 15.0 inches (38.1 cm), with inter-stub spacing of 4.6 inches (11.7 cm). Power handling is specified up to 10:1 VSWR at 25°C and sea level, with performance curves available for continuous wave operation. The tuner requires iterative adjustment of three short-circuited stubs to minimize reflection and maximize power transfer.
Stub tuners are impedance transformers designed to introduce a variable shunt susceptance into a coaxial transmission line. Maury offers a comprehensive line of broadband stub tuners designed to satisfy the majority of applications whether its to maximize power transfer between a generator and a load or for introducing a mismatch into an otherwise matched system. Spacing between the stubs of multiple-stub tuners will determine its range of impedances that can be matched and the ease of tuning.
