Magnetic coil power or voltage supply stabilizing device for filter in spectrum analyzers, has Hall sensor for detecting magnetic fields, and resonator i.e. yttrium iron garnet resonator, and sensor commonly arranged in body of filters

摘要

The device (1) has a Hall sensor (4) for detecting magnetic fields produced by a magnetic coil (23). A ferromagnetic or ferrimagnetic resonator i.e. yttrium iron garnet resonator, and the sensor are commonly arranged in a filter body of filters. The sensor is arranged in a recess of the filter body. The recess is provided at the filter body in a near surrounding of a resonator chamber, where the resonator chamber contains the resonator or resonators. The sensor is radially arranged at a longitudinal axis corresponding to symmetrical axis of the filter body in a displaceable manner.
