PRODUCTION METHOD OF BAND-PASS FILTERS FOR GHZ-BAND

摘要

FIELD: electricity.;SUBSTANCE: band-pass filter (BF) for GHz (gigahertz)-bands are arranged in pattern with input signal line and output signal line designed as conducting bands pass sequentially with close gap on one surface of sheet made by powdered soft-magnetic metal dispersion in polymer matrix. Internal line composed of conducting band with insulating layer added bypasses on signal lines. On reverse side the sheet has passing grounding line. Method provides application of semi-finished part produced by insulating layer attached on both parties of specified input signal line, output signal line and internal line, and inserted on one side of injection press mould enclosure, metal detail for grounding line on the other side of press mould enclosure, and injection of polymer composition to produce moulding product.;EFFECT: automation of small size band-pass filters production with high recovery of required frequency response.;7 cl, 9 dwg
