Okulambika okutwaliza awamu
SMB 75 Ohm PCB Male Connector ekoleddwa kkampuni ya Zhenjiang Tongda ye kiyungo kya RF coaxial ekitono nga kirimu enkola ya push-on quick-connect mechanism ne characteristic impedance ya 75Ω. Ekoleddwa okuteeka PCB, ekola ekigere ekitono, okwanguyirwa okugiteeka, n’omutindo gw’okutambuza ogutebenkevu.
Ensengeka y’ebyuma
1. Nyiga-ku Enkola y'okusiba
Okwawukanako n’ensengeka y’ebiyungo bya SMA ebiriko obuwuzi, ebiyungo bya SMB birina ekiyungo kya laasitiki eky’omunda munda mu nnyumba. Bwe kiyingizibwa mu jack enkazi eya SMB, collet egaziwa n’oluvannyuma n’edduka n’edda okukwata bbugwe ow’ebweru, okusobozesa okugatta okw’amangu, okwesiba nga tekyetaagisa kussaako wuzi. Ekuuma amaanyi g’okusiba era ekakasa okukwatagana okwesigika ne bwe wabaawo enzirukanya y’okugatta ezisukka mu 500.
2. Ensengeka y’Omuyungo Omusajja
Ekiyungo eky’ekika kya J- (ekisajja) kirina ppini ennywevu eya wakati efuluma ekoleddwa okuyingiza mu socket ya jack ey’ekikazi, okuteekawo okukwatagana kw’amasannyalaze okwesigika. Ensimbi ezikwatagana zisiigiddwa zaabu-okukendeeza ku buziyiza bw’okukwatagana n’okuwa obuziyiza bw’okukwatagana (oxidation resistance).
3. PCB Okuyita mu-Enzimba y’okussaako ebituli (E-ekika kya Straight Mount) .
Center pin: Esolder ku PCB signal pad okutambuza signals za RF;
Amagulu ag’oku ttaka ag’okumpi: Gasoda okuyita mu paadi z’oku ttaka eza PCB, nga gawa okuyungibwa ku ttaka okujjuvu, okumpi-ekkubo eri ennyumba y’ekiyungo;
Omulimu: Efunza grounding loop, ekendeeza ku RF return path impedance, eyongera ku shielding performance, era egaba mechanical stability against vibration.
Ebikulu ebipimo
| Pulojekiti | Parameter |
| Impedansi ey’engeri | 75Ω |
| Frequency y’okukola | DC-2GHz |
| VSWR | Ekitono oba ekyenkana 1.30 |
| Okuziyiza insulation | Okusinga oba okwenkana 1000MΩ |
| Gumira vvulovumenti | 750V |
| Okuziyiza okukwatagana | Pini ya wakati Entono oba yenkana 5 mΩ, ennyumba Entono oba yenkana 2.5 mΩ |
| Obulamu bw’enzirukanya y’okugatta | Okusinga oba okwenkana emirundi 500 |
| Ebbugumu ly’okukola | -65 diguli ~ +165 diguli |
Ebikozesebwa n’Obuyiiya
1. Omubiri: Ekintu eky’omusingi eky’ekikomo nga kiriko zaabu; rust-egumira, egumira nnyo okukwatagana, era nnyangu okusolder.
2. Pini wakati: Ekikomo oba ekikomo kya Beryllium nga kiriko zaabu; elasticity enywevu.
3. Insulator: PTFE (ebbugumu erya waggulu-, erya waggulu-frequency dielectric).
Ebirungi Ebiva mu Bikozesebwa
1. Sayizi entono-entono okusinga SMA-esaanira ensengeka za PCB eza density enkulu-.
2. Enkola ya Push-ku self-locking mechanism esobozesa okugatta n'okutagatta amangu nnyo okusinga ebiyungo bya SMA/BNC ebiriko threaded.
3. Okukwatagana okutuufu okwa 75Ω impedance kukakasa nti signal attenuation entono ku vidiyo ne CCTV applications.
4. Okunyweza okuyita mu-kituli soldering kiwa stable board-side connections n'okuziyiza okukankana.
5. Ebbeeyi ntono ate nga esaanira nnyo okufulumya mu bungi.
Ensonga enkulu ez’okukozesa
1. Okulondoola kwa analog n’okutambuza vidiyo ya coaxial HD (RG59/RG6 cable-ku-okuyungibwa ku bboodi)
2. Ku-board interfaces za cable TV ne signals eziweereza ku mpewo
3. Module za vidiyo transceiver ne modulation/demodulation circuit boards
4. Okuyungibwa kwa board-ku-ku waya ez'omunda ez'ebikozesebwa n'ebyuma ebigezesa RF
5. Emiryango gya RF egya kkamera z’ebyokwerinda ne vidiyo encoders
