Cholumikizira cha 90 Degree Hybrid, pafupipafupi 4 ~ 12GHz, Mphamvu yapakati 50W, SMA Yachikazi

Cholumikizira cha hybrid cha madigiri 90 ndi chipangizo chopanda mphamvu cha maikuloweredwe anayi. Chizindikiro chikalowa kuchokera ku chimodzi mwa madoko, chimagawa mphamvu ya chizindikirocho mofanana ku madoko awiri otulutsa (theka lililonse, mwachitsanzo -3dB), ndipo pali kusiyana kwa gawo la madigiri 90 pakati pa zizindikiro ziwiri zotulutsa. Chigawo china ndi chapadera, makamaka chopanda mphamvu zotulutsa. Zotsatirazi zikuwonetsa mwachidule makhalidwe ake ndi ntchito zake:

Zinthu Zofunika Kwambiri:

1. Kuphimba pafupipafupi kwa Ultra-wideband
Imathandizira ntchito ya ultra-wideband kuyambira 4 mpaka 12 GHz, ikuphimba bwino C-band, X-band, ndi gawo la mapulogalamu a Ku-band. Gawo limodzi limatha kulowa m'malo mwa zida zingapo za narrowband, kupangitsa kuti kapangidwe ka makina kakhale kosavuta komanso kuchepetsa zinthu zomwe zili m'sitolo ndi ndalama zomwe zimagwiritsidwa ntchito.
2. Mphamvu yogwiritsira ntchito mphamvu zambiri
Kapangidwe kabwino kwambiri ka kutentha ndi kapangidwe kake kamathandiza kuti magetsi azigwira bwino ntchito mpaka mphamvu yapakati ya 50W, zomwe zimakwaniritsa zofunikira za maulumikizidwe ambiri amphamvu kwambiri. Zimapereka kudalirika kwambiri komanso moyo wautali wautumiki.
3. Cholumikizira cha quadrature cha 3dB cholondola
Ili ndi kusiyana kolondola kwa magawo 90 (quadrature) ndi kulumikizana kwa 3dB. Imawonetsa bwino kwambiri amplitude balance komanso kutayika kochepa kwa insertion, ndikugawa bwino bwino chizindikiro cholowera m'ma signali awiri otulutsa omwe ali ndi amplitude yofanana ndi orthogonal phase.
4. Kudzipatula kwakukulu komanso kufananiza bwino madoko
Doko lodzipatulali limaphatikizapo katundu wofanana mkati, kupereka kudzipatula kwakukulu komanso kuchepetsa bwino kulumikizana kwa ma signal pakati pa ma doko, kuonetsetsa kuti dongosolo limakhala lolimba. Ma doko onse ali ndi voltage standing wave ratio (VSWR) yabwino kwambiri komanso kufananiza ma doko, zomwe zimachepetsa kuwunikira kwa ma signal kwambiri.
5. Mawonekedwe wamba a akazi a SMA
Ili ndi ma interface a SMA female (SMA-F), ogwirizana ndi miyezo yamakampani. Amapereka kulumikizana kosavuta komanso kodalirika, zomwe zimathandiza kuti igwirizane mwachindunji ndi zingwe zambiri za SMA zachimuna ndi ma adapter pamsika.
6. Ubwino wovuta wa asilikali
Yopangidwa ndi chitsulo chotetezedwa bwino, ili ndi kapangidwe kolimba, yolimba kwambiri ku kugwedezeka ndi kugwedezeka, komanso imakhala ndi chitetezo champhamvu kwambiri cha maginito. Imagwira ntchito bwino ngakhale m'malo ovuta.

Mapulogalamu Odziwika:

1. Makina a radar ophatikizidwa: Amagwira ntchito ngati gawo lofunikira mu Beamforming Networks (BFN), kupereka zizindikiro zolimbikitsa ndi ubale wapadera wa gawo ndi zinthu zingapo za antenna kuti zigwiritsidwe ntchito pofufuza kuwala kwa magetsi.
2. Makina a amplifier amphamvu kwambiri: Amagwiritsidwa ntchito popanga ma amplifier oyenera pogawa ndi kuphatikiza ma siginolo, kukulitsa mphamvu yotulutsa ndi kudalirika kwa makinawo pamene akukweza kufananiza kwa zolowetsa/zotulutsa.
3. Kusintha ndi kugawa chizindikiro: Imagwira ntchito ngati chopangira chizindikiro cha quadrature cha ma modulators a I/Q ndi ma demodulators, zomwe zimapangitsa kuti ikhale gawo lofunikira kwambiri mu njira zamakono zolumikizirana ndi radar.
4. Makina oyesera ndi kuyeza: Amagwira ntchito ngati chogawa mphamvu molondola, cholumikizira, kapena chipangizo chowunikira magawo m'mapulatifomu oyesera ma microwave kuti agawire zizindikiro, kuphatikiza, ndi kuyeza magawo.
5. Machitidwe a electronic countermeasure (ECM): Amagwiritsidwa ntchito popanga zizindikiro zovuta komanso kukonza zizindikiro, kukwaniritsa zofunikira za broadband ndi mphamvu zazikulu za machitidwe ankhondo zamagetsi.

Qualwave Inc. imapereka ma broadband ndi ma coupler amphamvu kwambiri a 90 degrees hybrid osiyanasiyana kuyambira 1.6MHz mpaka 50GHz, omwe amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Nkhaniyi ikubweretsa coupler yosakanikirana ya 90 degrees yokhala ndi mphamvu yapakati ya 50W pama frequency kuyambira 4 mpaka 12GHz.
