Ultra-wide band filter

Features : A non-complicated geometry, relatively high order of filtering,
SIR-combined design, applicable to other broadband filters or channel combiners

Table of the Frequency Response

Item Performance Remarks/Consideration
Frequency range 3.2 GHz – 10.8 GHz
Insertion loss |S21| ≥ -1 dB Planar structure, Dielectric loss
Return loss |S11| ≤ – 15 dB Planar structure, Dielectric loss
Stopband attenuation |S21| ≤ – 20 dB Planar structure, Dielectric loss

*A less lossy substrate adopted, the insertion and return loss of the filter will be surely improved with the quality-factor.
Strengths :

  1. The performance complies to the industrial standards. 성능은 표준규격 만족
  2. The unit stage is half the size of the conventional UWB filter or less 기존여파기의 반 정도 또는 더 작음.
  3. The cost of fabrication is half of that of the conventional UWB filter which employs many layers or complicated coupling elements. 다층구조나 복잡한 결합소자를 쓰는 기존 여파기보다 제작비용이 작음.
