Kuphatikiza pa mzere wa mzere wa RF Nthawi zambiri timakhala mu thumba la makadi ambiri osindikizidwa. Tsatirani mfundo zina:

A) wosanjikiza aliyense wa RF PCB imakutidwa ndi malo akulu osakhala ndi ndege. Zigawo zapamwamba komanso zotsika kwambiri za rf zotupa ziyenera kukhala ndege zoyambira.

Ngakhale ndi bolodi yokhala ndi digito-analog yosakanikirana, gawo la digito limatha kukhala ndi ndege yamagetsi, koma malo a RF amayenerabe kukwaniritsa zofunika kwambiri pa malo ambiri.

B) Kwa rf pagawo lapamwamba, pamwamba pa siginecha yosanjikiza, ndipo nthaka yapansi ndi ndege.

Awiri-wosanjikiza rf mmodzi bolodi, malo apamwamba ndi osanjikiza, zigawo zachiwiri ndi zisanu ndi zinayi zimakhala ndi ndege zapansi, ndipo gawo lachitatu ndi lamphamvu ndi mizere yamagetsi. M'malo mwapadera, mizere ina ya RF itha kugwiritsidwa ntchito pa gawo lachitatu. Zigawo zina za RF Boards, ndi zina zotero.
C) kwa RF Backplane, zigawo zapamwamba ndi m'munsi zonse zili pamalo. Pofuna kuchepetsa zomwe simumatha chifukwa cha mawu ndi zolumikizira, chachiwiri, chachitatu, chachinayi, ndi magawo asanu amagwiritsa ntchito zizindikiro za digito.

Zigawo zina zam'madzi pansi pali zigawo zonse zapansi. Momwemonso, zigawo ziwiri zoyandikana za RF Zizindikiro za RF ziyenera kukhala pansi, ndipo chilichonse chosanjikira chimayenera kuphimbidwa ndi dera lalikulu.

D) kwa mabodi apamwamba, okwera-a RF, ulalo wa RF wamkulu uyenera kuyikidwa pamwamba ndikulumikizidwa ndi mzere wa microstript.

Izi ndizothandiza kutentha kutentha ndi kusintha kwa mphamvu, kuchepetsa zolakwika za waya.

E) ndege yamphamvu ya digito iyenera kukhala pafupi ndi ndege yokhazikika ndikukonzekera pansi pa ndege.

Mwanjira imeneyi, kuchuluka kwa mbale ziwiri zachitsulo kumatha kugwiritsidwa ntchito ngati kaputi yothira mafuta, ndipo nthawi yomweyo, ndege ya nthaka ikhoza kutchingira ma radiation pa ndege yamagetsi.

Njira yogawika kapena njira yogawika ndege yomwe ingatanthauze zofuna za "2005018 zopangidwa ndi EMC-EMC zakuti" zidatsimikizika ndi dipatimenti ya Eda yopanga, komanso mfundo za pa intaneti zidzachitika.

RF Board Viring zofunika
2.1 ngodya

Ngati zizindikiro za RF zizindikiro zimapita kumanja, mzere wolimba umakulirakulira, ndipo choponderezana chimakhala chopanda tanthauzo ndikuyambitsa mawonekedwe. Chifukwa chake, ndikofunikira kuthana ndi ngodya, makamaka mu njira ziwiri: kudula ndi kuzungulira.

(2) Mutu wa arc uyenera kukhala waukulu wokwanira. Nthawi zambiri, onani: r> 3w.

2.2 micRostrip

Wosanjikiza wapamwamba wa PCB amanyamula chikwangwani cha rf, ndipo ndege yomwe ili pansi pa chikwangwani cha RF iyenera kukhala ndege yonse kuti ipange mawonekedwe a micressrip. Kuonetsetsa kuti kukhulupirika kwa mzere wa microstript, pali zofunikira:

. Ndipo mu magawo 3w, palibe mitundu yopanda basi.

(2) Mtunda pakati pa mzere wa microstrip ndi khoma loteteza liyenera kusungidwa pamwamba pa 2w. (Chidziwitso: W ndiye mtunda wa mzere).

. Bowo lalitali limakhala lochepera λ 20, ndipo adakonzedwa.

Mphepete mwa nthaka yamkuwa iyenera kukhala yosalala, yathyathyathya, ndipo palibe buledi wakuthwa. Ndikulimbikitsidwa kuti m'mphepete mwa mkuwa wapansi ndizambiri kuposa kapena wofanana ndi m'lifupi mwake 1.5w kapena 3h kuchokera m'mphepete mwa mzere wa microstpirit, ndipo H imayimira kukula kwa micRosrip.

2.3
Zizindikiro za Radialy nthawi zina zimadutsa pakati pa pcb. Chofala kwambiri ndi kuchokera pa gawo lachitatu. Zigawo zachiwiri ndi zisanu ndi zinayi ziyenera kukhala ndege yathunthu, ndiye kuti, kapangidwe kazinthu zokhala ndi eccentric. Kukhulupirika mwadongosolo kwa mzere wa Mzere kudzatsimikizika. Zofunikira zidzakhala:

.

. Bowo lalitali limakhala lochepera λ 20, ndipo adakonzedwa. Mphepete mwa nthaka yamkuwa iyenera kukhala yosalala, yosalala komanso yopanda kutentha.

Ndikulimbikitsidwa kuti m'mphepete mwa chikopa cham'mtengo wapatali ndi chachikulu kuposa kapena chofanana ndi m'lifupi 1 1.5w kapena mulifupi wa 3h kuchokera pamphepete mwa mzere wa Strip. H imayimira makulidwe athunthu am'mimba ndi otsika ma sekondale a mzere wa Strip.
