Lub Tshuab Ntes Duab Yees Duab Amplifier, 0.5~10GHz, -60~0dBm, 14mV/dB

Detector Log Video Amplifiers (DLVAs) yog ib qho tseem ceeb ntawm cov teeb liab hauv cov tshuab RF thiab microwave niaj hnub no. Nws ncaj qha ua qhov kev tshawb pom qhov siab tshaj plaws ntawm cov teeb liab RF nkag, logarithmically amplifying lub teeb liab video voltage tshwm sim, thiab thaum kawg tso tawm DC voltage uas muaj kev sib raug zoo nrog lub zog RF nkag. Hauv cov lus yooj yim, lub tshuab ntes video amplifier yog lub tshuab hloov pauv linear los ntawm "RF fais fab mus rau DC voltage." Nws tus nqi tseem ceeb yog nyob rau hauv nws lub peev xwm los compress RF cov teeb liab nrog qhov loj heev dynamic range mus rau hauv ib qho yooj yim dua, me dua DC voltage teeb liab, yog li ntawd yooj yim heev rau cov haujlwm ua cov teeb liab tom ntej xws li kev hloov pauv analog-rau-digital, kev sib piv / kev txiav txim siab, thiab kev tso saib.

Nta:

1. Kev them nqi zaus ultra-wideband
Qhov zaus ua haujlwm ntau ntawm 0.5GHz txog 10GHz, ua rau siv tau thoob plaws ntau qhov spectrum txij li L-band mus txog X-band. Ib chav tsev tuaj yeem hloov ntau lub cuab yeej narrowband, ua rau kev tsim qauv yooj yim dua.
2. Qhov tshwj xeeb dynamic ntau yam thiab rhiab heev
Nws muab cov tswv yim dav dav ntawm -60dBm txog 0dBm. Qhov no txhais tau tias nws tuaj yeem ntsuas cov teeb liab kom raug txij li qhov tsis muaj zog heev (-60dBm, nanowatt theem) mus rau qhov muaj zog heev (0dBm, milliwatt theem) tib lub sijhawm, ua rau nws zoo tagnrho rau kev ntes "cov teeb liab me me uas zais los ntawm cov teeb liab loj."
3. Kev sib txuas lus zoo thiab kev sib xws
Nws muab cov log linearity zoo heev thoob plaws tag nrho cov dynamic range thiab frequency band. Lub zog DC tso zis tswj hwm kev sib raug zoo linear nrog lub zog RF input, kom ntseeg tau tias cov txiaj ntsig ntsuas lub zog raug thiab txhim khu kev qha. Kev sib xws siab tau ua tiav ntawm cov channel (rau ntau-channel qauv) thiab thoob plaws cov pawg ntau lawm.
4. Kev teb ceev ceev heev
Nws muaj lub sijhawm nce/poob video nanosecond thiab lub sijhawm ua cov teeb liab qeeb. Nws tuaj yeem taug qab cov kev hloov pauv ntawm cov teeb liab pulse-modulated sai sai, ua tau raws li cov kev xav tau tiag tiag ntawm cov ntawv thov xws li radar pulse analysis thiab electronic support measures (ESM).
5. Kev koom ua ke siab thiab kev ntseeg siab
Siv cov thev naus laus zis ntawm qhov chaw thiab kev tsim qauv module sib xyaw ua ke, nws suav nrog lub tshuab ntes, lub tshuab ua kom lub zog loj (logarithmic amplifier), thiab lub voj voog them kub hauv lub tsev me me, uas muaj kev tiv thaiv. Nws muaj kev ruaj khov zoo ntawm qhov kub thiab txias thiab kev ua haujlwm tau ntev, tsim nyog rau cov chaw tub rog thiab kev lag luam uas nyuaj heev.

Cov ntawv thov:

1. Kev ua tsov rog hluav taws xob (EW) thiab cov cim qhia kev txawj ntse (SIGINT) systems
Kev ntsuas kev txhawb nqa hluav taws xob (ESM): Ua haujlwm ua lub hauv ntej rau cov khoom ceeb toom radar (RWR), ntsuas sai, txheeb xyuas, thiab nrhiav lub zog ntawm cov teeb liab radar rau kev paub txog kev hem thawj thiab tsim cov duab xwm txheej.
Kev txawj ntse hauv hluav taws xob (ELINT): Txheeb xyuas qhov tseeb ntawm cov yam ntxwv ntawm lub zog (qhov dav ntawm lub zog, qhov rov ua dua, lub zog) ntawm cov teeb liab radar tsis paub rau kev txheeb xyuas cov teeb liab thiab kev tsim cov ntaub ntawv kos npe.
2. Kev saib xyuas thiab tswj cov spectrum
Saib xyuas cov teeb liab ua haujlwm thoob plaws ntau zaus hauv lub sijhawm tiag tiag, ntsuas qhov tseeb ntawm cov teeb liab cuam tshuam tsis raug cai lossis cov teeb liab phooj ywg. Siv rau kev pom qhov xwm txheej spectrum, qhov chaw ntawm qhov cuam tshuam, thiab kev kuaj xyuas kev ua raws li spectrum.
3. Cov cuab yeej ntsuas thiab ntsuas kev ua tau zoo
Siv tau ua lub module nrhiav fais fab tseem ceeb hauv vector network analyzers (VNA), spectrum analyzers, lossis cov khoom siv kuaj tshwj xeeb, txuas ntxiv lub peev xwm ntsuas qhov ntau thiab tsawg ntawm cov cuab yeej, tshwj xeeb tshaj yog ua tau zoo hauv kev ntsuas lub zog pulse.
4. Cov tshuab radar
Siv rau kev saib xyuas kev tswj hwm qhov nce siab tsis siv neeg (AGC) hauv radar txais cov channel, saib xyuas lub zog tso zis ntawm lub transmitter, lossis ua haujlwm ua lub chaw txwv thiab lub zog nrhiav pom ntawm pem hauv ntej ntawm cov digital receivers (DRx) los tiv thaiv cov khoom rhiab heev tom qab.
5. Kev sib txuas lus thiab kev tshawb fawb thiab kev tsim kho hauv chaw kuaj mob
Siv rau kev saib xyuas thiab kho qhov txuas fais fab hauv cov kab ke sib txuas lus broadband (piv txwv li, kev sib txuas lus satellite, 5G / mmWave R & D). Hauv chav kuaj, nws yog ib qho cuab yeej zoo rau kev tshuaj xyuas cov yam ntxwv ntawm lub teeb liab thiab kev sim hluav taws xob.
