XHUMANA MANJE

Ama-Attenuators aguquguqukayo ahlanganisa izinhlobo ezimbili zomkhiqizo:

I-Rotary Step Attenuator kanye Ne-Attenuator Eguquguqukayo Ngokuqhubekayo.
I-Rotary Stepped Attenuator iyingxenye ye-elekthronikhi esetshenziselwa ukulawula amandla esignali. Isici sayo esiyinhloko ukuthi inenani elinqunyiwe lokuncishiswa okunyathelayo, ukuncishiswa kwesinyathelo ngasinye kuyalingana, futhi ukunemba kwesinyathelo kuphezulu, okungase kufinyelele ukuncishiswa kwesignali okunembile kakhulu.
Izibambisi eziguquguqukayo ezenziwa ngesandla yizingxenye ze-elekthronikhi ezingalawula ngokuqhubekayo amandla esignali. Isici sayo esiyinhloko ukuthi ingakwazi ukufeza ukuncishiswa kwesignali eqondile noma engaqondile ngokujikeleza noma ukushintsha i-voltage.

Izici mayelana ne-Rotary Stepped Attenuator:

1. Isinyathelo sokunciphisa: Lungisa ukuncipha ngokulinganayo isikhathi ngasinye.
2. Ukunemba okuphezulu: I-attenuator eguquguqukayo ngokuqhubekayo ingalawula amandla esignali phakathi kwebanga elinembile kakhulu.
3. Ukunciphisa isamba esikhulu: Isinciphisi sesinyathelo esijikelezayo singafinyelela noma sidlule ngisho nokuncipha okungu-90dB.
4. Umsindo ophansi: I-attenuator eguquguqukayo eqhubekayo ibhekwa njengohlobo lwe-passive attenuator olunomsindo ophansi ngokuqhathaniswa.

Isicelo mayelana ne-Rotary Stepped Attenuator:

1. Idivayisi yomsindo: I-Rotary variable attenuator esetshenziselwa ukulungisa usayizi wokukhishwa kwesiginali yesikhulisi samandla.
2. Imishini yokuxhumana: Isibambisi esishintshashintshayo mathupha sisetshenziselwa ukulungisa amandla okwamukela isignali ukuze kugwenywe ukulimala kwezisetshenziswa ezibangelwa amasignali aqine ngokwedlulele.
3. Ithuluzi lokulinganisa: Isifinyezo sokulawula mathupha sisetshenziselwa ukulungisa ngokunembile amandla esignali ukuze sihlangabezane nezidingo zokuhlola.
4. Imishini ye-Microwave: I-Rotary stepped atenuator esetshenziselwa ukulungisa usayizi nokuqina kwamasignali we-microwave.

Izici nge-Attenuator Eguquguqukayo Eqhubekayo:

1. Ukuguquguquka okuqhubekayo: Amandla esignali angalawulwa ngokuqhubekayo phakathi kwebanga.
2. Ukunemba okuphezulu: I-attenuator eguquguqukayo ekwazi ukufeza ukuncishiswa kwesignali enembe kakhulu.
3. Ukusabela okusheshayo: Isivinini sokuphendula isignali siyashesha futhi singalungiswa ngokushesha ukuze kuncishiswe.

Isicelo mayelana ne-Attenuator Eguquguqukayo Eqhubekayo:

1. Ukuxhumana okungenantambo: I-attenuator eguquguqukayo eqhubekayo esetshenziselwa ukulungisa amandla okwamukela isignali ukugwema ukulimala kwezinto zokusebenza ezibangelwa amasignali aqine ngokweqile.
2. Imishini yomsindo nevidiyo: Isibambisi esiguquguqukayo esisetshenziselwa ukulungisa usayizi namandla amasignali omsindo nevidiyo.
3. Isilinganiso sensimbi: I-Rotary variable attenuator esetshenziselwa ukulungisa ngokunembile amandla esignali ukuze ihlangabezane nezidingo zokuhlola.
4. Ukwamukela i-antenna: Kusetshenziselwa ukulungisa amandla esignali atholwe uthi ukuze kuthuthukiswe ikhwalithi yokwamukela.

Qualwaveihlinzeka nge-VSWR ephansi kanye nokuqina okuphezulu kwe-attenuation kusuka ku-DC kuya ku-40GHz. Ububanzi bokunciphisa bungu-0~121dB, izinyathelo zokunciphisa ngu-0.1dB, 1dB, 10dB. Futhi isilinganiso sokuphatha amandla singafika kuma-watts angu-300.
