Shaandheeyaha daloolka RF ee la habeeyey 437.5Mhz Band Gudbitaanka Shaandheeyaha
Filters-ka godka ayaa lagama maarmaan u ah shuruudahaaga isgaarsiineed. Keenlion, warshadeena hormuudka ka ah, waxay ku takhasustay soo saarista qalab isgaarsiineed oo tayo sare leh. Shaandhooyinkeena godka waxaa loo habeeyay si ay u bixiyaan khasaare hoose, yarayn sare, iyo awoodaha awood adag, taas oo ka dhigaysa mid ku haboon warshadaha isgaarsiinta mobilada iyo saldhigyada saldhiga. Shaandhooyinkan la beddeli karo ee Cavity-ga waxaa loo habeeyey si ay u wanaajiyaan waxqabadka nidaamkaaga isgaarsiineed, buuxinta baahiyaha gaarka ah iyo shuruudaha.
Dulmarka alaabta
Shaandhaynta godka, qayb lama huraan u ah baahiyahaaga isgaadhsiineed. Warshadayada, Keenlion, waa soo saare hormuud u ah agabka isgaadhsiinta oo tayo sare leh. Shaandhooyinkayaga godka waxaa loogu talagalay inay bixiyaan khasaaro hooseeya, attenuation sare, iyo awood sare oo awood, samaynta iyaga ku haboon ee warshadaha isgaarsiinta mobile iyo saldhigyada saldhiga.Our godka Filters waxaa loogu talagalay si kor loogu qaado waxqabadka nidaamka isgaarsiinta aad. Badeeco la beddeli karo, waxay buuxisaa baahiyaha iyo shuruudaha shakhsi ahaaneed.
Codsiyada caadiga ah
Nidaamka isgaarsiinta 1.Wireless - Filter Cavity waxaa loo isticmaali karaa hagaajinta soo noqnoqda iyo shaandhaynta hababka isgaarsiinta wireless, waxayna xaqiijin kartaa gudbinta calaamadaha waxqabadka sare.
2.Base station - Cavity Filter waxaa loo isticmaali karaa qaboojinta calaamadaha iyo shaandhaynta saldhigga saldhigga si loo hagaajiyo awoodda dareenka calaamadaha shabakada wireless.
3.Satellite isgaarsiinta - Cavity Filter waxaa loo isticmaali karaa shaandhaynta calaamadaha ee nidaamyada isgaarsiinta dayax-gacmeedka si loo hagaajiyo tayada calaamadaha iyo waxtarka gudbinta.
4.Aerospace - Cavity Filter waxaa loo isticmaali karaa nidaamyada isgaarsiinta diyaaradaha iyo shaandhaynta calaamadda radar ee garoonka hawada.
5. Isgaarsiinta Milatariga - Filter Cavity waxaa loo isticmaali karaa qaboojinta calaamadaha iyo shaandhaynta hababka isgaarsiinta milatariga si loo hubiyo gudbinta calaamadaha hufan iyo sirta.

Sawirka dulucda
Waa kuwan waxa aad u baahan tahay inaad ka ogaato waxyaabaha ku saabsan shaandhaynta godkayaga:
- Xadka soo noqnoqda: Waxaan bixinaa Filters Cavity si ay u waafajiyaan shuruudahaaga gaarka ah.
- Luminta Gelitaanka: Shaandheeyayaasha daloolkeena waxay bixiyaan khasaare gelin hoose, oo u dhaxaysa 0.2dB ilaa 2dB.
-Attenuation: Shaandhooyinkeena daloolku waxay bixiyaan feejignaan sare, oo u dhaxaysa 70dB ilaa 120dB.
- Xakamaynta Awoodda: Shaandhooyinkayaga godka waxaa loogu talagalay in lagu xakameeyo tamarta sare, oo u dhaxaysa 10W ilaa 200W.
