Malangizo：
Choyamba: Zinthu zosungiramo microstrip circulator kwa nthawi yayitali:
1, Kutentha kwapakati: +15℃~+25℃
2, Kutentha kwachibale: 25% ~ 60%
3, Siziyenera kusungidwa pafupi ndi mphamvu zamaginito kapena zinthu za ferromagnetic. Ndipo mtunda wotetezeka pakati pa zinthu uyenera kusungidwa:
Ma microstrip circulators okhala ndi ma frequency pamwamba pa X-band ayenera kulekanitsidwa ndi kupitirira 3mm
Nthawi yodziwika pakati pa ma circulator a C-band microstrip ndi yoposa 8mm
Awiri: Ma microstrip circulators omwe ali pansi pa ma frequency a C-band ayenera kulekanitsidwa ndi kupitirira 15mm
2. Onani mfundo zotsatirazi posankha ma microstrip circulators:
1. Mukalumikiza ndi kufananiza ma circuits, ma microstrip isolators amatha kusankhidwa; Microstrip circulator ingagwiritsidwe ntchito ikamasewera duplex kapena circular mu circuit
2. Sankhani mtundu wa microstrip circulator wogwirizana ndi kuchuluka kwa ma frequency, kukula kwa kukhazikitsa ndi njira yotumizira yomwe yagwiritsidwa ntchito.
3, pamene ma frequency ogwirira ntchito a kukula konse kwa microstrip circulators amatha kukwaniritsa zofunikira za chitsimikizo, mphamvu yayikulu yamagetsi imakhala yokwera.
Chachitatu: Chachitatu, kukhazikitsa microstrip circulator
1. Mukagwiritsa ntchito microstrip circulator, dera la microstrip pa doko lililonse siliyenera kumangidwa kuti lisawonongeke ndi makina.
2. Kusalala kwa malo oyikapo pokhudzana ndi pansi pa microstrip circulator sikuyenera kupitirira 0.01mm.
3. Chozungulira cha microstrip chomwe chayikidwa sichiyenera kuchotsedwa. Ndikoyenera kuti chozungulira cha microstrip chomwe chachotsedwacho chisagwiritsidwenso ntchito.
4. Mukagwiritsa ntchito zomangira, pansi pake sipayenera kukhala ndi zinthu zofewa monga indium kapena tin kuti mbale ya pansi pa chinthucho isasinthe zomwe zimapangitsa kuti ferrite substrate isweke; Limbitsani zomangira motsatizana, mphamvu yoyika: 0.05-0.15Nm
5. Pamene guluu waikidwa, kutentha kwa chotenthetsera sikuyenera kupitirira 150℃. Ngati wogwiritsa ntchito ali ndi zofunikira zapadera (ayenera kudziwitsidwa kaye), kutentha kwa chotenthetsera sikuyenera kupitirira 220℃.
6. Kulumikizana kwa dera la microstrip circulator kumatha kulumikizidwa ndi soldering ya mkuwa kapena golide strip/bonding pamanja
A. Cholumikizira cha lamba wa mkuwa ndi dzanja chomwe chimalumikizidwa ndi lamba wa mkuwa chiyenera kukhala Ω bridge, ndipo kutayikira sikuyenera kulowa m'malo opangira lamba wa mkuwa monga momwe chithunzichi chikusonyezera. Kutentha kwa pamwamba pa ferrite kuyenera kusungidwa pakati pa 60-100℃ musanagwiritse ntchito.
b, kugwiritsa ntchito lamba wagolide/waya wolumikizirana, m'lifupi mwa lamba wagolide ndi wochepera m'lifupi mwa dera la microstrip, palibe kulumikiza kosiyanasiyana komwe kumaloledwa, mtundu wa kulumikiza uyenera kukwaniritsa zofunikira za njira ya GJB548B 2017.1 Nkhani 3.1.5, mphamvu ya kulumikiza iyenera kukwaniritsa zofunikira za njira ya GJB548B 2011.1 ndi 2023.2.
Zinayi: kugwiritsa ntchito microstrip circulator ndi njira zodzitetezera
1. Kuyeretsa kwa microstrip circuit kumaphatikizapo kuyeretsa dera lisanayambe kulumikizidwa ndi kutsuka malo olumikizirana ndi kulumikiza mkuwa pambuyo polumikiza mkuwa. Kuyeretsa kuyenera kugwiritsa ntchito mowa, acetone ndi zinthu zina zosungunulira zosalowerera kuti kutsuke kutuluka kwa madzi, kuti chotsukiracho chisalowe m'dera lolumikizirana pakati pa maginito okhazikika, pepala la ceramic ndi substrate ya dera, zomwe zimakhudza mphamvu ya mgwirizano. Wogwiritsa ntchito akakhala ndi zofunikira zapadera, kutuluka kwa madzi kumatha kutsukidwa ndi kuyeretsa kwa ultrasound ndi zinthu zosungunulira zosalowerera monga mowa ndi madzi osungunuka, ndipo kutentha sikuyenera kupitirira 60 ° C ndipo nthawi siyenera kupitirira mphindi 30. Pambuyo poyeretsa ndi madzi osungunuka, kutentha ndi kouma, kutentha sikuyenera kupitirira 100℃.
2, ayenera kulabadira kugwiritsa ntchito
a. Kupitirira kuchuluka kwa ma frequency ogwiritsira ntchito ndi kutentha komwe kumagwiritsidwa ntchito, magwiridwe antchito a chinthucho adzachepa, kapena sadzakhala ndi mawonekedwe osagwirizana.
b. Chozungulira cha microstrip chikulimbikitsidwa kuti chisawonongeke. Mphamvu yeniyeni ikulimbikitsidwa kuti ikhale yochepera 75% ya mphamvu yoyesedwa.
c. Sipayenera kukhala mphamvu ya maginito yamphamvu pafupi ndi malo oyikapo chinthucho kuti mphamvu ya maginito yamphamvu isasinthe mphamvu ya maginito ya chinthucho ndikupangitsa kuti magwiridwe antchito a chinthucho asinthe.
