Shaandheynta Pim Hoose

RF shaandhada baasaska yar ee PIM Shaandhaynta gees-goynta ah waxaa loogu talagalay inay bixiso waxqabad heersare ah, shaandhaynta calaamadaha aan loo baahnayn iyo yaraynta isdhexgalka nidaamka saddexaad (IMD-dalabka 3aad) ee nidaamyada RF.

Marka laba calaamadood oo ku jira nidaamka toosan ay la falgalaan arrimo aan toos ahayn, habka saddexaad ee isdhexgalka ayaa dhacaya, taas oo keenta calaamado been abuur ah. Shaandhooyinkeena RF Low ee PIM Bandpass waxaa loo habeeyey si ay u bixiyaan shaandhayn heer sare ah oo ay yareeyaan saamaynta qallooca isdhexgalka, si wax ku ool ah loo yareeyo arrintan.

Naqshaddooda horumarsan iyo injineernimada saxda ah, filtarradayada bandpass waxay bixiyaan doorasho heer sare ah, taasoo u oggolaanaysa kaliya calaamadaha RF ee la doonayo inay gudbaan iyadoo la yareynayo soo noqnoqoshada aan loo baahnayn. Tani waxay hubinaysaa in nidaamkaaga RF uu ku shaqeeyo hufnaan ugu fican iyo faragelin yar, hagaajinta tayada calaamadaha iyo waxqabadka guud.

Haddi aad ka shaqaynayso isgaadhsiinta, isku xidhka bilaa-waayirka ah, ama codsi kasta oo RF ah, filtarradayada bandpass-yar ee RF ee hooseeya ayaa ah xalka ugu fiican ee gudbinta signalada la isku halayn karo. Dhismaheeda qallafsan iyo qaybaha tayada sare leh ayaa ka dhigaya mid ku habboon xaalado badan oo deegaan iyo shaqo.

Marka lagu daro awoodooda shaandhaynta sare, filtarradayada bandpass waxaa loogu talagalay in si fudud loogu daro nidaamyada RF ee jira, iyaga oo ka dhigaya xal la taaban karo oo la taaban karo oo codsiyo kala duwan ah. Waxqabadkooda la isku halayn karo iyo dhismahooda waara, waxaad ku aamini kartaa RF-yadayada shaandhada baasaska yar ee PIM si ay u keenaan natiijooyin joogto ah oo dalbanaya deegaan RF.

Khibrad u yeelo kala duwanaanshaha filtarrada baasaska yar ee RF ee hooseeya waxay u keeni karaan nidaamkaaga RF. U cusboonaysii xalkan sifaynta cusub oo u qaado waxqabadkaaga RF heerka xiga.
