Imikorere yimikorere ya RF

Guhindura RF na microwave birashobora kohereza ibimenyetso neza muburyo bwo kohereza.Imikorere yibi bisobanuro irashobora kurangwa nibintu bine byibanze byamashanyarazi.Nubwo ibipimo byinshi bifitanye isano nimikorere ya RF na microwave, ibipimo bine bikurikira bifatwa nkibyingenzi kubera isano ikomeye:

Kwigunga
Kwigunga ni attenuation hagati yinjiza nibisohoka byumuzunguruko.Ni igipimo cyo guca intege imikorere ya switch.

Igihombo
Igihombo cyo gushiramo (nanone cyitwa gutakaza igihombo) nimbaraga zose zabuze iyo switch iri muri leta.Igihombo cyo gushiramo nikintu gikomeye cyane kubashushanya kuko gishobora kuganisha ku kwiyongera kw urusaku rwa sisitemu.

Guhindura igihe
Guhindura igihe bivuga igihe gikenewe cyo kuva kuri "kuri" leta ukajya kuri "kuzimya" no kuva kuri "kuzimya" ukajya kuri "kuri" leta.Iki gihe gishobora kugera kuri microseconds ya power power switch na nanosekonds ya power power yihuta.Igisobanuro gikunze kugaragara cyo guhinduranya igihe nigihe gikenewe kuva kwinjiza kwinjiza voltage igera kuri 50% kugeza kumashanyarazi ya nyuma ya RF agera kuri 90%.

Ubushobozi bwo gutunganya ingufu
Byongeye kandi, ubushobozi bwo gukoresha ingufu busobanurwa nkimbaraga nini ya RF yinjiza ishobora guhinduka idashobora kwangirika kwamashanyarazi ahoraho.

Guhindura leta ikomeye ya RF
Guhindura leta ikomeye ya RF irashobora kugabanwa muburyo butagaragaza nubwoko bwo gutekereza.Ihinduramiterere ridahwitse rifite ibikoresho bya 50 ohm bihuza na résistor kuri buri cyambu gisohoka kugirango ugere ku gipimo gito cya voltage ihagaze (VSWR) haba muri leta no hanze yacyo.Ikirangantego cyimyanya ndangagitsina cyashyizwe ku cyambu gisohoka gishobora gukuramo ingufu zerekana ibimenyetso, mugihe icyambu kidafite aho gihurira nacyo kizerekana ibimenyetso.Iyo ibimenyetso byinjira bigomba gukwirakwizwa muri switch, icyambu cyafunguwe hejuru cyahagaritswe kuva kuri terefone ihuye na rezistor, bityo bigatuma ingufu z'ikimenyetso zikwirakwizwa rwose uhereye kuri switch.Guhindura ibintu bikwiranye na porogaramu aho echo yerekana isoko ya RF igomba kugabanywa.

Ibinyuranyo, ibyerekanwa byerekana ntabwo bifite ibikoresho birwanya imbaraga zo kugabanya igihombo cyo kwinjiza ibyambu bifunguye.Guhindura ibintu birakwiriye kubisabwa bitumva imbaraga za voltage ihagaze hejuru yikigereranyo.Mubyongeyeho, muburyo bwo guhinduranya ibintu, guhuza impedance bigerwaho nibindi bice usibye icyambu.

Ikindi kintu kigaragara kiranga leta-ihinduranya ni disiki zabo.Ubwoko bumwebumwe bukomeye-leta ihinduranya hamwe ninjiza igenzura voltage.Iyinjiza igenzura voltage logic leta yabashoferi irashobora kugera kubikorwa byihariye byo kugenzura - gutanga ibyangombwa bikenewe kugirango tumenye neza ko diode ishobora kubona reaction cyangwa imbere ya bias voltage.

Imashanyarazi ya elegitoroniki kandi ikomeye-ya RF irashobora gukorwa mubicuruzwa bitandukanye bifite uburyo butandukanye bwo gupakira hamwe nubwoko bwihuza - ibicuruzwa byinshi bya coaxial bihinduranya hamwe na frequence ikora kugeza kuri 26GHz ikoresha SMA ihuza;Kugera kuri 40GHz, 2.92mm cyangwa K-ubwoko bwa K bizakoreshwa;Kugera kuri 50GHz, koresha 2.4mm umuhuza;Kugera kuri 65GHz koresha 1.85mm ihuza.
