Amplifier yamphamvu kwambiri ya RF MM0810P47B

Chojambulira champhamvu cha RF MM0810P47B ndi chinthu cha RF cha multi-octave chomwe chimagwira ntchito pakati pa 800 MHz ndi 1000 MHz. Chimapereka mphamvu zambiri zosinthika ndi mphamvu ya saturated ya 50 Watts, ndipo mphamvu yowonjezera ndi 47dB. Kusalala kwa mphamvu ya chojambulira champhamvu ichi ndi ±1dB, zomwe zimapangitsa kuti chizindikiro cha RF chisasokonezeke kwambiri ndipo chimapereka kukhazikika kwa chizindikiro komanso khalidwe labwino. Ndi kutayika kwa kubweza kwa input mpaka -10dB, ma amplifiers amphamvu a Mars RF ali ndi mwayi wokhala ndi zizindikiro zolandirira ndi kutulutsa zokhazikika komanso magwiridwe antchito abwino a antenna. Chojambulira champhamvu cha RF ichi chili ndi kuletsa ndi kutulutsa kwa 50 ohms ndipo chimatha kulumikizidwa bwino ndi makina amagetsi.

Amplifier iyi yamphamvu kwambiri imagwiritsa ntchito ma transistors a LDMOS. Mu ma amplifiers a RF, LDMOS imagwiritsidwa ntchito kwambiri m'malo olumikizirana ndi ma wailesi oyenda kutengera ubwino wa mtengo wotsika, kuphatikiza kwakukulu, komanso DPD (Digital Pre-Distrotion) yabwino kwambiri. Pakati pawo, malo olumikizirana ndi malo olumikizirana ndi gawo lalikulu kwambiri la LDMOS.

Mkati mwa chipangizochi cha MM0810P47A chothandizira mphamvu zambiri chimapangidwa ndi aluminiyamu, chomwe chimathandiza kuchepetsa kulemera kwa chinthu chonse cha RF, komanso chili ndi mphamvu zabwino kwambiri, komanso kukana dzimbiri, komanso kuwala kwambiri. Chimatetezedwa ku infrared ndi RF radiation ndipo chimakhala cholimba komanso cholimba kuposa zipangizo zina.

Chojambulira champhamvu cha RF cha Mars chilinso ndi ntchito yoteteza dera, yomwe imayamba kugwira ntchito yokha ngati mphamvu yamagetsi yakwera kwambiri, kutentha kwa chojambulira champhamvu kwambiri kupitirira 85°C, ndipo magetsi ndi > 32V. Chitetezo cha dera chikayamba kugwira ntchito, wogwiritsa ntchito ayenera kuzimitsa chizindikiro cholowera ndi magetsi, ndikudikirira kuti chojambulira champhamvu kwambiri chizizire ndikuyambiranso. Ngati chitetezo cha dera chikayamba kugwira ntchito kachiwiri, chonde onani ngati katundu ndi kutentha kwapitirira malire, komanso ngati kulumikizana kwa katundu kuli kwabwinobwino.

√ Broadband & Mphamvu yayikulu;

√ Kugwiritsa Ntchito Bwino Kwambiri;

√ Mzere Waukulu;

√ Kukula Kochepa & Kulemera Kopepuka;

√ Kupotoka Kochepa

Chitsimikizo chaulere cha amplifier yamphamvu kwambiri ya Mars RF ndi zaka zitatu.

1. Ngati kasitomala ali ndi luso lokonza, tidzapereka zidazo kuti zithandize kasitomala kukonza yekha, njira iyi ndi yothandiza kwambiri.

2. Ngati kasitomala alibe mphamvu kapena vuto lokonza, pakakhala vuto ladzidzidzi, tidzapereka zinthu zatsopano, ndipo kasitomala adzatibwezera zinthu zomwe zawonongeka pambuyo pake.

Pambuyo pa chitsimikizo cha zaka zitatu, tidzaperekabe chithandizo chaukadaulo kwa kasitomala, kasitomala ayenera kupereka ndalama zokonzera ndi ndalama zomwe zagwiritsidwa ntchito.
