Chinopa Mavhidhiyo Ekuongorora Log, 0.1~20GHz, 60dBm, 30mV/dB

MaDetector Log Video Amplifiers (DLVAs) chikamu chepakati chekugadzirisa masaini muRF yemazuva ano uye masisitimu ema microwave. Anoona zvakananga RF signal, anowedzera logarithmically vhidhiyo voltage signal inobuda, uye pakupedzisira anoburitsa DC voltage ine hukama hwakafanana neRF power inopinza. Muchidimbu, detector log video amplifier ichinja-chinja kubva ku "RF power kuenda kuDC voltage." Kukosha kwayo kukuru kuri mukukwanisa kwayo kudzvanya masaini eRF ane dynamic range yakakura kwazvo kuita chiratidzo cheDC voltage chinogoneka, chidiki, nokudaro zvichiita kuti mabasa ekugadzirisa masaini akatevera ave nyore sekushandura analog kuenda kudigital, kuenzanisa/kuita sarudzo, uye kuratidza.

Hunhu:

1. Kufukidzwa kwemafrequency ebhendi rakafara zvakanyanya
Mafrequency ekushanda anotangira pa0.1GHz kusvika pa20GHz, zvichiita kuti mashandiro ashande kubva paL-band kusvika kuX-band. Chishandiso chimwe chete chinogona kutsiva michina yakawanda ye narrowband, zvichiita kuti dhizaini yesystem ive nyore.
2. Nzvimbo inoshamisa yesimba
Inopa huwandu hunoshanduka hunosvika 60dB, ichinyatsosiyanisa pakati pezviratidzo zvakasimba nezvisina simba uku ichichengetedza kunyatsoyera uye kugona kwezviratidzo kunyangwe munzvimbo dzakaoma kunzwisisa.
3. Kurongeka kwakarurama kwerogi uye kuenderana kwayo
Inopa log linearity yakanaka kwazvo mu dynamic range yese uye frequency band. Iyo output DC voltage inochengetedza hukama hwakasimba hwe linear nesimba re RF rekupinda, zvichiita kuti pave nemhedzisiro chaiyo uye yakavimbika yekuyera simba. Kuenderana kwakanyanya kunowanikwa pakati pema channels (ema multi-channel models) uye muma batches ekugadzira.
4. Kukurumidza kupindura nekukurumidza
Iine nguva yekukwira/kudonha kwevhidhiyo yedanho repamusoro uye kunonoka kwekugadzirisa masaini. Inogona kuteedzera nekukurumidza kusiyana kwemasaini anogadziriswa nekurova kwemoyo, ichizadzisa zvinodiwa panguva chaiyo zvemashandisirwo akadai sekuongorora kwekurova kwemoyo neradar uye zviyero zvekutsigira zvemagetsi (ESM).
5. Kubatanidzwa kwakanyanya uye kuvimbika
Ichishandisa tekinoroji yekugadzika pamusoro pechinhu uye dhizaini yemodule yakabatanidzwa, inosanganisira detector, logarithmic amplifier, uye temperature compensation circuitry mukati meimba diki, yakachengetedzwa. Inoratidza kugadzikana kwakanaka kwetembiricha uye kuvimbika kwekushanda kwenguva refu, yakakodzera nharaunda dzinoda mauto nemaindasitiri.

Mashandisirwo:

1. Masisitimu ehondo yemagetsi (EW) uye ehungwaru hwezviratidzo (SIGINT)
Matanho ekutsigira emagetsi (ESM): Anoshanda senzira yekubatsira vanogamuchira yambiro yeradar (RWR), achikurumidza kuyera, kuona, uye kuwana simba rezviratidzo zveradar zvehasha kuti vazive njodzi uye kugadzira mifananidzo yemamiriro ezvinhu.
Unyanzvi hwemagetsi (ELINT): Inoongorora nemazvo hunhu hwekurova kwemoyo (upamhi hwekurova kwemoyo, kudzokorora kwemoyo, simba) rezviratidzo zveradar zvisingazivikanwe zvekugadzirisa zviratidzo uye kugadzira database yechiratidzo.
2. Masisitimu ekutarisa nekutarisira maspektrum
Inotarisa mashandiro ezviratidzo pabhendi rema frequency akawanda munguva chaiyo, ichiyera nemazvo mazinga esimba rezviratidzo zvinokanganisa zvisiri pamutemo kana zviratidzo zvine hushamwari. Inoshandiswa pakuona mamiriro ezvinhu e spectrum, nzvimbo inobva kukanganiswa, uye kutarisa kutevedzera spectrum.
3. Zvishandiso zvekuyedza zvine simba uye zvekuyera
Inogona kushandiswa se critical power detection module mu vector network analyzers (VNA), spectrum analyzers, kana specialized test equipment, zvichiita kuti chishandiso chikwanise kuyera dynamic range, kunyanya kugona kuyera pulse power.
4. Masisitimu eradar
Inoshandiswa pakutarisa otomatiki gain control (AGC) muma radar receiving channels, kutarisa transmitter power output, kana kushanda se dimitting and power detection unit pamberi pe digital receivers (DRx) kudzivirira zvinotevera se sensitive components.
5. Kutaurirana uye R&D yerabhoritari
Inoshandiswa pakuongorora simba rekubatanidza uye kugadzirisa masisitimu ekutaurirana kwebroadband (semuenzaniso, kutaurirana kwesatellite, 5G/mmWave R&D). Murabhoritari, chishandiso chinoshanda chekuongorora hunhu hwechiratidzo chepulse uye kuyedza power sweep.

Qualwave Inc. inopaMaAmplifiers eDetector Logzvinosanganisa zvakakwana bandwidth yakafara, kunzwa kwakanyanya, kupindura nekukurumidza, uye kurongeka kwakanaka, nemafrequencies anosvika ku40GHz. Rugwaro urwu rwunosuma Detector Log Video Amplifier ine frequencies ye0.1 ~ 20GHz.
