Chinopa Mavhidhiyo Ekuongorora Log, 0.5~10GHz, -60~0dBm, 14mV/dB

Chinoburitsa Mavhidhiyo eDetector Logs (DLVAs) chikamu chepakati chekugadzirisa masaini muRF yemazuva ano uye masisitimu ema microwave. Inoita zvakananga kuona peak pachiratidzo cheRF chinopinzwa, inowedzera logarithmically vhidhiyo voltage inobuda, uye pakupedzisira inoburitsa DC voltage ine hukama hwakafanana nesimba reRF rinopinzwa. Muchidimbu, detector log video amplifier ichinjiri chemutsetse 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 anotevera ave nyore senge analog-to-digital conversion, kuenzanisa/kuita sarudzo, uye kuratidza.

Zvimiro:

1. Kufukidzwa kwemafrequency ebhendi rakafara zvakanyanya
Mafrequency ekushanda anotangira pa0.5GHz kusvika pa10GHz, 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. Hunhu hwakanaka uye kunzwisisika kunoshamisa
Inopa mukana wakakura wekupinda kubva pa -60dBm kusvika pa 0dBm. Izvi zvinoreva kuti inogona kuyera nemazvo zviratidzo kubva pakuderera zvakanyanya (-60dBm, nanowatt level) kusvika pakusimba zvishoma (0dBm, milliwatt level) panguva imwe chete, zvichiita kuti ive yakakodzera kubata "zviratidzo zvidiki zvakavharirwa nezviratidzo zvikuru."
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 ye nanosecond level uye kunonoka kwekugadzirisa masaini. Inogona kuteedzera nekukurumidza kusiyana kwemasaini anogadziriswa nepulse, ichizadzisa zvinodiwa panguva chaiyo zvemashandisirwo akadai se radar pulse analysis uye electronic support measures (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 ma spectrum
Inotarisa mashandiro ezviratidzo pabhendi remafrequency akawanda munguva chaiyo, ichiyera nemazvo mazinga esimba rezviratidzo zvinokanganisa zvisiri pamutemo kana zviratidzo zvine hushamwari. Inoshandiswa pakuona mamiriro ezvinhu espectrum, 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 dimigrant uye 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. inopa maDetector Log Video Amplifiers anobatanidza zvakakwana bandwidth yakafara, kunzwa kwakanyanya, kupindura nekukurumidza, uye kurongeka kwakanaka, nemafrequencies anosvika ku40GHz.
Rugwaro urwu rwunosuma Detector Log Video Amplifier ine frequency coverage ye0.5~10GHz.
