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 :
- The performance complies to the industrial standards. 성능은 표준규격 만족
- The unit stage is half the size of the conventional UWB filter or less 기존여파기의 반 정도 또는 더 작음.
- 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.
