Isikhulisi Somsindo Esiphansi, Imvamisa 0.1 ~ 18GHz, Inzuzo engu-30dB, Umdwebo Womsindo 3dB

I-amplifier yomsindo ophansi iyithuluzi likagesi elisetshenziselwa ukukhulisa amasignali abuthakathaka, elisetshenziswa kabanzi emikhakheni efana nokuxhumana, i-radar, i-radio astronomy, njll.

Izici:

1. Isilinganiso somsindo ophansi
Isibalo somsindo sisetshenziselwa ukuchaza izinga lokuwohloka komsindo wesiginali yokufaka yi-amplifier, futhi iyinkomba yokukala ukusebenza komsindo we-amplifier. I-coefficient yomsindo ophansi isho ukuthi i-amplifier yethula umsindo omncane kakhulu ngenkathi ikhulisa isiginali, okungalondoloza kangcono ulwazi lokuqala lwesiginali futhi kuthuthukise isilinganiso sesiginali kuya komsindo sohlelo.
2. Inzuzo ephezulu
Ukwanda okuphezulu kungakhulisa izimpawu zokufaka ezibuthakathaka zibe yi-amplitude eyanele yokucubungula isekethe okulandelayo. Isibonelo, ekuxhumaneni ngesathelayithi, izimpawu zesathelayithi sezivele zibuthakathaka kakhulu uma zifika esiteshini sokwamukela phansi, futhi ukwanda okuphezulu kwama-amplifier omsindo ophansi kungakhulisa lezi zimpawu ukuze zisuswe futhi ziqhutshwe ngokuqhubekayo.
3. Ukusebenza kwebhendi ebanzi noma ibhendi ethile yemvamisa
Ama-amplifier omsindo ophansi angaklanywa ukuthi asebenze ngebhendi yemvamisa ebanzi futhi angakhulisa amasignali ebangeni lemvamisa ebanzi.
4. Ukulingana okuphezulu
Ukulingana okuphezulu kwe-amplifier yomsindo ophansi kuqinisekisa ukuthi izici ze-waveform kanye nemvamisa yesiginali aziphazanyisiwe ngesikhathi senqubo yokukhulisa, okuqinisekisa ukuthi lezi zimpawu zisengancishiswa futhi zibonwe ngokunembile ngemva kokukhulisa.

Isicelo:

1. Insimu yokuxhumana
Ezinhlelweni zokuxhumana ezingenantambo, njengokuxhumana kwefoni ephathekayo, inethiwekhi yendawo engenantambo (i-WLAN), njll., i-amplifier yomsindo ophansi iyisici esibalulekile se-receiver front-end. Yandisa izimpawu ze-RF ezibuthakathaka ezitholwa yi-antenna ngenkathi inciphisa ukwethulwa komsindo, ngaleyo ndlela ithuthukise ukuzwela kokwamukela kohlelo lokuxhumana.
2. Uhlelo lwe-radar
Uma amaza kagesi akhishwa yi-radar exhumana nethagethi bese ebuyela ku-radar receiver, amandla esignali aba buthaka kakhulu. I-amplifier yomsindo ophansi ikhulisa la masignali e-echo abuthakathaka engxenyeni engaphambili ye-radar receiver ukuze ithuthukise ikhono lokubona le-radar.
3. Izinsimbi namamitha
Kwezinye izinsimbi zokulinganisa ze-elekthronikhi ezinemba kakhulu, njengezihlaziyi ze-spectrum, izihlaziyi zesignali, njll., ama-amplifier anomsindo ophansi asetshenziswa ukukhulisa isignali elinganisiwe, ukuthuthukisa ukunemba kokulinganisa kanye nokuzwela kwethuluzi.

I-Qualwave Inc. inikeza imodyuli ye-amplifier yomsindo ophansi noma umshini wonke kusukela ku-DC kuya ku-260GHz. Ama-amplifier ethu asetshenziswa kabanzi kwezentambo ezingenantambo, kuma-receiver, ekuhlolweni kwelabhorethri, kuma-radar nakwezinye izinkambu.
Lesi sihloko sethula i-amplifier enomsindo ophansi enobubanzi bemvamisa obungu-0.1 ~ 18GHz, inzuzo engu-30dB, kanye nesibalo somsindo esingu-3dB.
