Taybetmendî:
- Rakirina Rawestandina Bilind
- Small Size
Parzûnek derbasbûna nizm parzûnek hilberandina sînyalê ye ku bi rakirina sînyalên frekansa bilind îşaretên frekansa nizm diparêze. Ew dihêle ku sînyalên bi frekansên ji bendek diyarkirî kêmtir derbas bibin, lê îşaretên bi frekansên ji wê bendekê mezintir red dike.
1. Tenê sînyalên li jêr frekansek taybetî têne destûr kirin ku derbas bibin, lê îşaretên li jor wê frekansê têne fîltrekirin an qels kirin.
2. Dema ku di nav sînyalên frekansa nizm re derbas dibin, di qonaxê de hema hema ti guhertin çênabe.
3. Bi gelemperî, yek an jî çend kondensator û înduktor têne bikar anîn da ku fîlterên kêm-pass ava bikin.
1.sînyala hênik
Parzûna nizm-derbasbûnê bi gelemperî ji bo sivikkirina sînyalê tê bikar anîn, ew dikare dengê di sînyala frekansa bilind de derxîne, da ku îşaret aramtir bibe. Di rewşên ku îşaretek bêkêmasî hewce ye, parzûna kêm-derbasbûnê dikare dengê destwerdana frekansa bilind rake, bi vî rengî pergalê pêbawer û aramtir dike.
2.kêmkirina deng
Parzûna kêm-derbasbûnê dê bandorê li sînyala frekansa nizm neke, dema ku sînyala frekansa nizm bigire, dengê frekansa bilind dikare were fîltre kirin. Di pêvajoya deng an jî hilberandina wêneyê de, fîlterên kêm-derbas dikarin deng derxînin û sînyala pêvajoyî zelaltir bikin.
3.kemkirina xeletiyê
Parzûna kêm-derbasbûnê dikare xeletiyê kêm bike, nemaze ji bo pîvandina amûra rast. Di hin pîvandinên daxwazî de, parzûna kêm-derbasbûnê dikare deng, destwerdan û faktorên din rake, da ku encamên pîvandinê rasttir û pêbawertir bin.
4.berfirehiya sepanê
Parzûna kêm derbasbûnê xwedan cûrbecûr serlêdanan e, ji deng heya wêneyê, ji ragihandinê heya kontrolê, hema hema li her deverê. Mînakî, di hilberandina sînyala baseband de, parzûnek nizm-derbasbûnê pêdivî ye.
Di ragihandinê de, parzûna nizm-derbasbûnê dikare dengê frekansa bilind, destwerdan, hwd., fîlter bike da ku qalîteya ragihandinê peyda bike; Di warê kontrolê de, parzûna kêm-derbasbûnê dikare ji bo sivikkirina nîşanê û fîlterkirina dengan were bikar anîn.
QualwaveParzûnên redkirina rawestgeha bilind a kêm derbasbûnê di rêza frekansa DC-50GHz de peyda dike. Parzûnên derbasbûna kêm di gelek sepanan de bi berfirehî têne bikar anîn.
