Ii-IQ Mixers RF Microwave Millimeter Wave High Frequency Radio
IiMicrowave Mixers luhlobo olukhethekileyo lomxube oluqulathe iindlela ezimbini zesignali zesigaba esihambelanayo ezibizwa ngokuba yi-"In-phase" (I) kunye ne-"Quadrature" (Q). Iimpawu zayo zezi zilandelayo:
1. Nika ulwazi lwesigaba kunye nobukhulu: Ngenxa yokubandakanywa kweetshaneli ze-I kunye ne-Q, umxube we-IQ werediyo unokubonelela ngolwazi lwesigaba kunye nobukhulu bomqondiso. Oku kubalulekile kwiinkqubo ezininzi zonxibelelwano ezingenazingcingo kunye neenkqubo zokuguqula kunye nokunciphisa amandla.
2. Qaphela ukusetyenzwa kwesignali ye-orthogonal: Iitshaneli ze-I kunye ne-Q ze-RF mixers ziyakwazi ukusetyenzwa kwesignali ye-orthogonal, oko kukuthi, imiqondiso enomahluko wesigaba sama-90 degrees. Oku kwenza i-radio frequency mixer ibe luncedo kakhulu kwiindlela ezininzi zokuguqula kunye nokunciphisa, ezifana ne-orthogonal frequency division multiple access (OFDM) kunye ne-quadrature amplitude modulation (QAM).
3. Ukuphazamiseka kokumamela okuncitshisiweyo: Umxubi we-IQ unako ukwahlula i-signal kunye ne-interference spectrum ngenxa yokufakwa kweendlela ezimbini ezihambelanayo zesigaba. Oku kuyenza ikwazi ngakumbi ukulwa nokuphazamiseka kokumamela.
4. Uluhlu oluphezulu lwe-dynamic: Ngenxa yokusetyenziswa kweendlela ezimbini, abaxubi be-IQ bahlala benoluhlu oluphezulu lwe-dynamic olunokuhlangabezana nezicelo zokucubungula isignali ezifunekayo.
Umxubi we-IQ usetyenziswa ngokubanzi kwezi zinto zilandelayo:
1. Iinkqubo zonxibelelwano ezingenazingcingo: I-Millimeter wave mixer isetyenziswa kakhulu kwiinkqubo zonxibelelwano ezingenazingcingo, kuquka iinkqubo zonxibelelwano eziphathwayo, iinkqubo zonxibelelwano lwesathelayithi kunye neenethiwekhi zengingqi ezingenazingcingo. Isetyenziselwa ukunciphisa isignali efunyenweyo, ukuguqula isignali ethunyelweyo, kunye nokufezekisa ukuchithwa, ukuguqulwa kunye nokuguqulwa kwamaza omqondiso.
2. IiModem:Ii-IQ mixers zizinto ezibalulekileyo ezifumaneka rhoqo kwiimodem ezisetyenziselwa ukuxuba imiqondiso yebaseband kwi-RF range ukuze zidluliselwe, okanye ukuxuba imiqondiso yeRF efunyenweyo kwibaseband ukuze kususwe amandla.
3.Ukuhanjiswa kwedatha ngesantya esiphezulu: Ngenxa yokuba abaxubi be-IQ banokuphatha imiqondiso ye-orthogonal, banezicelo ezibalulekileyo ekuhanjisweni kwedatha ngesantya esiphezulu. Umzekelo, kwiinkqubo zonxibelelwano lwe-optical kunye nonxibelelwano lwedijithali olukhawulezayo, ukuguqulwa kwe-QAM kunye nokususwa kwedatha kusetyenziswa abaxubi be-IQ kunokwenza ukuba ukuhanjiswa kwedatha ngesantya esiphezulu nangomthamo ophezulu kusebenze.
4. Uhlalutyo lokuphazamiseka kwe-carrier: Abaxubi be-IQ bangasetyenziselwa uhlalutyo lokuphazamiseka kwe-carrier, olunokunceda ekuchongeni umthombo wokuphazamiseka nokuphelisa ukuphazamiseka ngokulinganisa nokuhlalutya ulwazi lwesigaba kunye nobukhulu besignali.
I-QualwaveI-Inc. ibonelela nge-IQ-mixers esebenza ukusuka kwi-1.75 ukuya kwi-26GHz.
