Chojambulira Makanema cha Detector Log, 0.1~20GHz, 60dBm, 30mV/dB

Ma Detector Log Video Amplifiers (DLVAs) ndi gawo lofunikira kwambiri pakusintha kwa ma signal mu RF yamakono ndi ma microwave. Amazindikira mwachindunji chizindikiro cha RF cholowera, amakulitsa chizindikiro cha voteji ya kanema chomwe chimachokera, ndipo pamapeto pake amatulutsa voteji ya DC yomwe ili ndi ubale wolunjika ndi mphamvu ya RF yolowera. Mwachidule, chojambulira makanema cha detector log ndi chosinthira cholunjika kuchokera ku "mphamvu ya RF kupita ku voteji ya DC." Mtengo wake waukulu uli mu kuthekera kwake kukanikiza ma signal a RF okhala ndi mphamvu yayikulu kwambiri kukhala chizindikiro cha voteji cha DC chosavuta kugwiritsa ntchito, motero kumachepetsa kwambiri ntchito zotsatizana monga kusintha kwa analog kupita ku digito, kufananiza/kupanga zisankho, ndi kuwonetsa.

Makhalidwe:

1. Kuphimba pafupipafupi kwa Ultra-wideband
Ma frequency ogwirira ntchito amakhala pakati pa 0.1GHz ndi 20GHz, zomwe zimathandiza kuti ntchito igwiritsidwe ntchito pamitundu yosiyanasiyana kuyambira L-band mpaka X-band. Chida chimodzi chimatha kusintha zida zingapo za narrowband, zomwe zimapangitsa kuti kapangidwe kake kakhale kosavuta.
2. Mitundu yodabwitsa yamphamvu
Imapereka mphamvu yosinthasintha mpaka 60dB, kusiyanitsa bwino pakati pa zizindikiro zamphamvu ndi zofooka pamene ikusunga kulondola kwabwino kwa muyeso ndi kutsimikiza kwa zizindikiro ngakhale m'malo ovuta kwambiri.
3. Kulondola kwa log linearity ndi kusasinthasintha
Imapereka mzere wabwino kwambiri wa log mu dynamic range yonse ndi frequency band. Mphamvu ya DC yotulutsa imasunga ubale wolimba wa linear ndi input RF power, kuonetsetsa kuti zotsatira zolondola komanso zodalirika za muyeso wa mphamvu zimapezeka. Kugwirizana kwakukulu kumachitika pakati pa ma channel (a mitundu ya ma channel ambiri) komanso m'magulu onse opanga.
4. Liwiro loyankha mwachangu kwambiri
Ili ndi nthawi yokwera/kugwa kwa kanema wa nanosecond level komanso kuchedwa kwa kukonza ma signal. Imatha kutsatira mwachangu kusiyana kwa ma pulse-modulated signals, kukwaniritsa zofunikira zenizeni za mapulogalamu monga radar pulse analysis ndi electronic support measures (ESM).
5. Kuphatikiza kwakukulu ndi kudalirika
Pogwiritsa ntchito ukadaulo woyika pamwamba pa malo komanso kapangidwe kake ka ma module ophatikizidwa, imaphatikiza chowunikira, chowongolera cha logarithmic, ndi ma circuitry ochepetsa kutentha mkati mwa nyumba yaying'ono komanso yotetezedwa. Imawonetsa kukhazikika kwa kutentha bwino komanso kudalirika kwa nthawi yayitali, yoyenera malo ovuta ankhondo ndi mafakitale.

Mapulogalamu:

1. Machitidwe ankhondo zamagetsi (EW) ndi ma signaling intelligence (SIGINT)
Njira zothandizira zamagetsi (ESM): Zimathandiza ngati njira yowunikira machenjezo a radar (RWR), kuyeza mwachangu, kuzindikira, ndikupeza mphamvu ya zizindikiro za radar zotsutsana kuti zidziwitse zoopsa komanso kupanga zithunzi zomwe zikuchitika.
Luntha la zamagetsi (ELINT): Limasanthula bwino momwe ma pulse alili (kuchuluka kwa ma pulse, kuchuluka kwa ma frequency, mphamvu) ya ma radar osadziwika kuti asankhe ma signal ndi kupanga database yodziwika bwino.
2. Njira zowunikira ndi kuyang'anira ma sipekitiramu
Imayang'anira zochitika za ma signal pa ma frequency ambiri nthawi yeniyeni, kuyeza molondola kuchuluka kwa mphamvu za ma signal osaloledwa kapena ma signal abwino. Imagwiritsidwa ntchito powonetsa momwe zinthu zilili pa spectrum, komwe kumachokera ma connection, komanso kuyang'anira kutsata malamulo a spectrum.
3. Zipangizo zoyesera bwino komanso zoyezera
Ingagwiritsidwe ntchito ngati gawo lofunikira lozindikira mphamvu mu vector network analyzers (VNA), spectrum analyzers, kapena zida zapadera zoyesera, kukulitsa luso la chida choyezera mphamvu, makamaka bwino kwambiri pakuyesa mphamvu ya pulse.
4. Makina a radar
Amagwiritsidwa ntchito poyang'anira automatic gain control (AGC) mu radar receiving channels, kuyang'anira transmitter power output, kapena kugwira ntchito ngati limiting and power detection unit kutsogolo kwa digital receivers (DRx) kuti ateteze zigawo zina zokhudzidwa.
5. Kuyankhulana ndi kafukufuku ndi chitukuko cha labotale
Imagwiritsidwa ntchito poyang'anira mphamvu zolumikizirana ndi kuwerengera mu machitidwe olumikizirana a broadband (monga, kulumikizana kwa satellite, 5G/mmWave R&D). Mu labotale, ndi chida chothandiza kwambiri pakusanthula kwa zizindikiro za pulse ndi kuyesa kwa power sweep.

Qualwave Inc. imaperekaZokulitsa Makanema a Detector Logzomwe zimaphatikiza bwino kwambiri bandwidth yotakata, kukhudzidwa kwambiri, kuyankha mwachangu, komanso kulumikizana bwino kwambiri, ndi ma frequency ofikira mpaka 40GHz. Lembali likuwonetsa Detector Log Video Amplifier yokhala ndi ma frequency ofikira 0.1 ~ 20GHz.
