Lub tshuab sib xyaw ua ke yog lub cuab yeej siv hluav taws xob uas sib xyaw ob lub teeb liab ua ke los tsim cov teeb liab tso zis, uas tuaj yeem txhim kho qhov rhiab heev, kev xaiv, kev ruaj khov, thiab kev sib xws ntawm cov ntsuas zoo ntawm lub receiver. Nws yog ib qho tseem ceeb uas siv rau kev ua cov teeb liab hauv cov kab ke microwave. Hauv qab no yog kev qhia los ntawm ob qho tib si nta thiab kev siv:
Cov yam ntxwv:
1. Kev pab them nqi dav dav (17 ~ 50GHz)
Lub tshuab sib xyaw ua ke no txhawb nqa qhov ntau zaus ultra dav ntawm 17GHz txog 50GHz, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev sib txuas lus satellite, 5G millimeter nthwv dej, radar systems, thiab lwm yam, txo qhov nyuaj ntawm kev hloov pauv nruab nrab hauv kev tsim qauv.
2. Kev poob qis qis, kev rho tawm siab
Los ntawm kev siv cov qauv sib xyaw ua ke, qhov xau ntawm cov oscillator hauv zos (LO) thiab cov teeb liab xov tooj cua zaus (RF) raug tshem tawm zoo, muab kev cais tawm zoo heev thaum tswj kev poob qis, ua kom muaj kev sib kis teeb liab siab.
3. Cov ntim khoom ruaj khov, tsim nyog rau cov chaw ib puag ncig hnyav
Lub plhaub hlau muab kev tiv thaiv hluav taws xob zoo heev thiab kev ua haujlwm kub dissipation, nrog rau qhov kub ua haujlwm ntawm -55 ℃ ~ + 85 ℃, tsim nyog rau cov tub rog, aerospace, thiab cov khoom siv sib txuas lus hauv thaj chaw.
Cov ntawv thov:
1. Kev kuaj thiab ntsuas microwave: Nws ua haujlwm ua lub hauv paus tseem ceeb hauv cov khoom siv kuaj siab xws li Vector Network Analyzers thiab Spectrum Analyzers. Nws yog siv rau kev ntsuas zaus txuas ntxiv, kev kuaj xyuas cov khoom (piv txwv li, amplifiers, antennas), thiab kev tshuaj xyuas teeb liab, muab cov ntaub ntawv millimeter-wave txhim khu kev qha rau R&D thiab kev tsim khoom.
2. Kev sib txuas lus los ntawm satellite: Siv dav hauv K/Ka-band satellite ground stations, VSAT terminals, thiab low-earth orbit (LEO) internet systems (piv txwv li, Starlink). Nws ua up-conversion rau uplink transmission thiab down-conversion rau downlink receiving.
3. 5G thiab wireless backhaul: Nws ua lub luag haujlwm hloov pauv zaus tseem ceeb hauv 5G millimeter-wave base stations (piv txwv li, 28/39GHz) thiab E-Band point-to-point wireless backhaul systems, ua rau nws yog tus pab tseem ceeb rau kev xa cov ntaub ntawv wireless ceev ceev.
4. Kev Ua Rog Hluav Taws Xob (ECM): Ua tiav kev tshuaj xyuas cov teeb liab rhiab heev hauv cov chaw muaj hluav taws xob nyuaj.
Qualwave Inc. muab cov coaxial thiab waveguide balanced mixers nrog rau qhov ua haujlwm zaus ntawm 1MHz txog 110GHz, siv dav hauv kev sib txuas lus niaj hnub, kev tiv thaiv hluav taws xob, radar, thiab kev sim thiab ntsuas teb. Tsab xov xwm no qhia txog coaxial balanced mixer nrog kev ua haujlwm ntawm 17 ~ 50GHz.
