Mumakore achangopfuura, nekukura nekukurumidza kwekutaurirana kwe wireless uye radar tekinoroji, kuitira kuvandudza daro rekutumirwa kwe system, zvakakosha kuwedzera simba rekutumirwa kwe system. Sechikamu che microwave system yese, RF coaxial connectors dzinofanirwa kukwanisa kutsungirira zvinodiwa zvekutumirwa kwe high power ability. Panguva imwe chete, mainjiniya eRF anofanirwawo kuita bvunzo dze high power uye zviyero kakawanda, uye zvishandiso/zvikamu zve microwave zvinoshandiswa pakuedza kwakasiyana-siyana zvinofanirwawo kukwanisa kutsungirira high power. Ndezvipi zvinhu zvinokanganisa simba rekutumirwa kwe RF coaxial connectors? Ngationei.
●Saizi yekubatanidza
Kune masaini eRF ane frequency imwe chete, maconnector makuru ane simba rakanyanya kushivirira. Semuenzaniso, saizi ye connector pinhole ine chekuita nekugona kwe connector kuripo, uko kwakabatana zvakananga nesimba. Pakati pemaconnector akasiyana-siyana anowanzo shandiswa eRF coaxial, 7/16 (DIN), 4.3-10, uye N-type connectors akakura zvakanyanya, uye saizi dze pinhole dzinoenderana dzakakurawo. Kazhinji, simba re connectors dzeN-type rinokwana SMA ka3-4. Pamusoro pezvo, maconnector eN-type anonyanya kushandiswa, ndosaka zvikamu zvakawanda zvisingashande zvakaita se attenuators uye loads dziri pamusoro pe200W zviri N-type connectors.
●Kushanda kakawanda
Kushivirira simba reRF coaxial connectors kuchaderera sezvo frequency yesignal ichiwedzera. Kuchinja kwefrequency yesignal yekutumira kunotungamira zvakananga kukuchinja mukurasikirwa uye voltage standing wave ratio, nokudaro zvichikanganisa kugona kwesimba rekutumira uye mhedzisiro yeganda. Semuenzaniso, general SMA connector inogona kutsungirira inosvika 500W yesimba pa2GHz, uye avhareji yesimba inogona kutsungirira isingasviki 100W pa18GHz.
●Chiyero chemagetsi chakamira
Chinobatanidza RF chinotsanangura hurefu hwemagetsi panguva yekugadzira. Mumutsetse une hurefu hwakaganhurirwa, kana hunhu hweimpedance uye load impedance zvisina kuenzana, chikamu chevoltage ne current kubva kumagumo emutoro zvinoratidzwa zvichidzokera kudivi remagetsi, iro rinonzi wave. Mafungu anoratidzwa; voltage ne current kubva kunobva kuenda kumutoro zvinonzi mafungu ezviitiko. Wave inobuda yewave yezviitiko uye wave inoratidzwa inonzi wave yakamira. Chiyero chehuwandu hwevoltage yepamusoro uye kukosha kudiki kwewave yakamira chinonzi voltage yakamira wave (inogonawo kuva iyo standing wave coefficient). Wave inoratidzwa inogara munzvimbo yekugona kwechiteshi, zvichiita kuti simba rekutumira riderere.
●Kurasikirwa kwekuisa
Kurasikirwa kwekuisa (IL) zvinoreva kurasikirwa kwesimba patambo nekuda kwekuiswa kweRF connectors. Zvinotsanangurwa sechiyero chesimba rekubuda nesimba rekupinda. Pane zvinhu zvakawanda zvinowedzera kurasikirwa kwekuisa kweconnector, zvinonyanya kukonzerwa ne: kusawirirana kwecharacteristic impedance, assembly accuracy error, mating end face gap, axis tilt, lateral offset, eccentricity, processing accuracy uye electroplating, nezvimwewo. Nekuda kwekuvapo kwekurasikirwa, pane musiyano pakati pesimba rekupinda nerekubuda, izvo zvichakanganisawo simba rinogara riripo.
●Kumanikidzwa kwemhepo kwakakwira
Kuchinja kwekumanikidzwa kwemhepo kunokonzera shanduko mukusimba kwe dielectric kwechikamu chemhepo, uye kana mhepo yadzikira, mhepo inogadziriswa zviri nyore kuti ibudise korona. Kana kukwirira kwacho kwakakwira, kumanikidzwa kwemhepo kunoderedza uye simba remagetsi rinenge diki.
●Kuramba kubata
Kuramba kwekubatana kweRF connector kunoreva kuramba kwenzvimbo dzekubatana dzemukati nekunze kweconductors kana connector yabatanidzwa. Kazhinji iri mu milliohm level, uye kukosha kwayo kunofanira kunge kudiki sezvinobvira. Inonyanya kuongorora hunhu hwemakanika ekubatana, uye mhedzisiro yekuramba kwemuviri uye kuramba kwejoini re solder inofanira kubviswa panguva yekuyerwa. Kuvapo kwekurambana kuchaita kuti kubatana kupise, zvichiita kuti zviome kutumira masaini e microwave ane simba guru.
●Zvinhu zvekubatana
Rudzi rumwe chete rwechinobatanidza, uchishandisa zvinhu zvakasiyana, ruchava nekushivirira kwakasiyana kwesimba.
Kazhinji, kana tichitarisa simba reantenna, funga nezvesimba rayo pachayo nesimba reconnector. Kana paine chikonzero chesimba rakawanda, unogonagadzirisachinobatanidza simbi isingatsvi, uye 400W-500W hapana dambudziko.
