Band-pass filter with loop forming electrodes - forming magnetically coupled unit, while another electrodes is fitted to other side of plate

摘要

The loop electrodes (41-43) are magnetically coupled while another electrode (5) is flat and formed on a plate on the obverse side of the first electrodes. The dielectric plate is sandwiched between the two electrode types. From each first electrode an earth terminal (6a-c) extends in the direction of the plate end section (A). An outwardly leading terminal (7a,b) from the first electrodes is arranged with a preset impedance w.r.t. the earth terminal in a spacing from the plate end section. From the second electrode another earth terminal (8a-c) extends in the direction of the plate end section. USE/ADVANTAGE - Dielectrically laminated band pass filter, with high quality and negligible mounting attenuation, and adjustable pass band mean frequency.
