M'makina oyesera ma microwave, ma switch a RF ndi ma microwave amagwiritsidwa ntchito kwambiri poyendetsa ma siginecha pakati pa zida ndi ma DUT.Pakuyika chosinthira mu makina osinthira matrix, ma siginecha ochokera ku zida zingapo amatha kupita ku DUT imodzi kapena zingapo.Izi zimathandiza kuti mayesero angapo amalize kugwiritsa ntchito chipangizo chimodzi choyesera popanda kufunikira kwa kulumikizidwa pafupipafupi ndi kulumikizanso.Ndipo imatha kukwaniritsa makina oyesera, potero imathandizira kuyezetsa bwino m'malo opanga zinthu zambiri.
Zizindikiro zazikulu za ntchito zosinthira zigawo
Kupanga kothamanga kwambiri kwamasiku ano kumafuna kugwiritsa ntchito zida zosinthira kwambiri komanso zobwerezabwereza pazida zoyesera, malo olumikizirana, ndi makina oyesera okha.Masiwichi awa amatanthauzidwa molingana ndi izi:
Nthawi zambiri
Ma frequency osiyanasiyana a ntchito za RF ndi ma microwave amayambira 100 MHz mu semiconductors mpaka 60 GHz mumayendedwe a satana.Zomata zoyeserera zokhala ndi ma frequency ambiri ogwirira ntchito zawonjezera kusinthasintha kwa makina oyesera chifukwa chakukulirakulira kwa kuphimba pafupipafupi.Koma kuchuluka kwa magwiridwe antchito kumatha kukhudza magawo ena ofunikira.
Kutayika kolowetsa
Kutayika kolowetsa ndikofunikiranso pakuyesa.Kutayika kwakukulu kuposa 1 dB kapena 2 dB kudzachepetsa msinkhu wa chizindikiro, kuonjezera nthawi yokwera ndi kugwa.M'malo ogwiritsira ntchito maulendo apamwamba kwambiri, kufalitsa mphamvu zogwira mtima nthawi zina kumafuna mtengo wokwera kwambiri, choncho zotayika zowonjezera zomwe zimayambitsidwa ndi kusintha kwa electromechanical mu njira yosinthira ziyenera kuchepetsedwa momwe zingathere.
Bwererani kutaya
Kutayika kobwerera kumawonetsedwa mu dB, yomwe ndi muyeso wa voltage Stand wave ratio (VSWR).Kutayika kobwerera kumachitika chifukwa cha kusagwirizana pakati pa mabwalo.Munthawi ya ma frequency a microwave, mawonekedwe azinthu ndi kukula kwa magawo a netiweki amatenga gawo lofunikira pakuzindikiritsa kufananitsa kapena kusagwirizana komwe kumachitika chifukwa cha kugawa.
Kusasinthika kwa magwiridwe antchito
Kusasinthika kwa magwiridwe antchito otsika otayika kumatha kuchepetsa zolakwika zomwe zachitika mwachisawawa panjira yoyezera, potero kumapangitsa kuti muyeso ukhale wolondola.Kusasinthika ndi kudalirika kwa kusintha kwa magwiridwe antchito kumatsimikizira kulondola kwa kuyeza, ndikuchepetsa mtengo wa umwini pokulitsa mizere yoyezera ndikuwonjezera nthawi yoyeserera.
Kudzipatula
Kudzipatula ndiko kuchepetsedwa kwa ma siginecha opanda ntchito omwe amapezeka padoko la chidwi.Pamaulendo apamwamba, kudzipatula kumakhala kofunika kwambiri.
Chithunzi cha VSWR
VSWR ya switch imatsimikiziridwa ndi makulidwe amakina ndi kulolerana kwa kupanga.VSWR yosauka ikuwonetsa kukhalapo kwa zowunikira zamkati zomwe zimayambitsidwa ndi kusagwirizana, ndipo zizindikiro za parasitic zomwe zimayambitsidwa ndi izi zimatha kuyambitsa kusokoneza kwa chizindikiro (ISI).Zowunikirazi nthawi zambiri zimachitika pafupi ndi cholumikizira, kotero kufananiza kolumikizira bwino ndi kulumikizidwa koyenera ndizomwe zimafunikira kuyesa.
Kusintha liwiro
Kuthamanga kwa switch kumatanthauzidwa ngati nthawi yofunikira kuti doko losinthira (sinthidwe mkono) lichoke ku "kuya" kupita ku "kuzimitsa", kapena kuchokera "kuzimitsa" kupita ku "kuyatsa".
Nthawi yokhazikika
Chifukwa chakuti nthawi yosinthira imangotchula mtengo womwe umafika pa 90% ya mtengo wokhazikika / womaliza wa chizindikiro cha RF, nthawi yokhazikika imakhala ntchito yofunika kwambiri ya masinthidwe olimba pansi pa zofunikira za kulondola ndi kulondola.
Kukhala ndi mphamvu
Mphamvu yonyamula imatanthauzidwa ngati mphamvu yosinthira kunyamula mphamvu, yomwe imagwirizana kwambiri ndi mapangidwe ndi zipangizo zomwe zimagwiritsidwa ntchito.Pakakhala mphamvu ya RF/microwave pa doko losinthira pakusintha, kusintha kwamafuta kumachitika.Kusintha kozizira kumachitika pamene mphamvu ya chizindikiro yachotsedwa musanasinthe.Kusintha kozizira kumachepetsa kupsinjika kwapamtunda komanso moyo wautali.
Kuthetsa
M'mapulogalamu ambiri, kuyimitsa katundu wa 50 Ω ndikofunikira.Chosinthiracho chikalumikizidwa ku chipangizo chogwira ntchito, mphamvu yowonekera yanjirayo popanda kuyimitsa katundu ikhoza kuwononga gwero.Kusintha kwamagetsi kumatha kugawidwa m'magulu awiri: omwe ali ndi kuletsa katundu ndi omwe alibe kuletsa katundu.Zosintha zolimba zitha kugawidwa m'mitundu iwiri: mtundu wa mayamwidwe ndi mtundu wowunikira.
Video kutayikira
Kutulutsa kwamavidiyo kumatha kuwonedwa ngati ma siginecha a parasitic omwe akuwonekera pa switch RF port pomwe palibe chizindikiro cha RF.Zizindikirozi zimachokera ku ma waveforms opangidwa ndi dalaivala wosinthira, makamaka kuchokera ku ma spikes amagetsi akutsogolo omwe amafunikira kuyendetsa chosinthira chothamanga kwambiri cha PIN diode.
Moyo wothandizira
Moyo wautali wautumiki udzachepetsa mtengo ndi zovuta za bajeti pakusintha kulikonse, kupangitsa opanga kukhala opikisana kwambiri pamsika wamasiku ano wovuta kwambiri.
Kapangidwe ka switch
Mitundu yosiyanasiyana ya masinthidwe imapereka kusinthasintha pomanga ma matrices ovuta komanso makina oyesera odziyimira pakugwiritsa ntchito ndi ma frequency osiyanasiyana.
Amagawidwa m'modzi mwa awiri (SPDT), amodzi mwa atatu kunja (SP3T), awiri awiri kunja (DPDT), ndi zina zotero.
