FIELD: radio engineering. ^ SUBSTANCE: pass-band filter includes hollow metal screen (MS) (1) on the ends of which there installed are connectors (2) to circuits of supply lines, n open disc (OD) dielectric resonators (3), where integral number nëÑ1, holders in the form of metal pins (MP) (4) the end surfaces of which are soldered to inner surface (5) of hollow MS (1). Flat surface of OD dielectric resonators (3) of equal length is bonded to opposite end surfaces of each of three MP (4). After connectors (2) are connected to the circuit with the propagating SHF wave, extreme OD dielectric resonators (3) enable the input and output of energy in filter - transmission line system. Hollow MS (1), which is out-of-limit in the service band of the filter, excludes out-of-band transmission of energy between input and output and provides electromagnetic communication of OD dielectric resonators (3) to each other. ^ EFFECT: improving heat removal from open disc dielectric resonators at maintaining high effective basic Q of resonant filter sections and high electric characteristics of the filter. ^ 6 cl, 5 dwg |
