Binciken manyan bambance-bambance tsakanin eriya ta RF da eriya ta microwave

A fannin na'urorin haska hasken lantarki, eriya na RF da eriya na microwave galibi suna rikicewa, amma akwai bambance-bambance na asali. Wannan labarin yana gudanar da bincike na ƙwararru daga girma uku: ma'anar mitar mita, ƙa'idar ƙira, da tsarin kera, musamman haɗa manyan fasahohi kamarinjin ƙona injin.

RF MISOInjin Tanderu Mai Amfani da Injin

1. Kewayon mitar da halayen jiki
Eriya ta RF:
Mitar mitar aiki ita ce 300 kHz - 300 GHz, tana rufe watsa shirye-shiryen matsakaicin raƙuman ruwa (535-1605 kHz) zuwa millimeter wave (30-300 GHz), amma aikace-aikacen tsakiya suna da yawa a cikin <6 GHz (kamar 4G LTE, WiFi 6). Tsawon tsayin ya fi tsayi (santimita zuwa matakin mita), tsarin galibi shine dipole da whip eriya, kuma ƙarfin haƙuri ga haƙuri yana da ƙasa (±1% tsayin tsayin ya dace).

Eriya ta microwave:
Musamman 1 GHz - 300 GHz (wave na microwave zuwa milimita), madannin mitar aikace-aikace na yau da kullun kamar X-band (8-12 GHz) da Ka-band (26.5-40 GHz). Bukatun gajeriyar tsawon rai (matakin milimita):
✅ Daidaiton aikin matakin submillimeter (juriya ≤±0.01λ)
✅ Tsananin sarrafa ƙaiƙayi a saman (< 3μm Ra)
✅ Ƙananan ƙarancin asarar dielectric substrate (ε r ≤2.2, tanδ≤0.001)

2. Tsarin fasahar masana'antu
Aikin eriya na microwave ya dogara sosai akan fasahar kera kayayyaki masu inganci:

Fasaha Eriya ta RF Eriya ta Microwave
Fasahar haɗi Maƙallin haɗakarwa/sukurori An yi wa injin tsotsa
Masu Kaya na yau da kullun Masana'antar Kayan Lantarki ta Janar Kamfanonin yin amfani da na'urar dumama abinci kamar Solar Atmospheres
Bukatun walda Haɗin mai sarrafawa Rashin shigar iskar oxygen, sake tsara tsarin hatsi
Ma'aunin Mahimmanci Juriya akan <50mΩ Daidaita ma'aunin faɗaɗa zafi (ΔCTE <1ppm/℃)

Babban darajar brazing na injin tsotsa a cikin eriya na microwave:
1. Haɗin da ba shi da iskar oxygen: yin amfani da bracing a cikin yanayin injin 10-5 Torr don guje wa iskar oxygen daga ƙarfen Cu/Al da kuma kula da watsawa >98% IACS
2. Kawar da damuwa ta zafi: dumamawa mai sauƙi zuwa sama da ruwan da ke cikin kayan ƙarfafawa (misali BAISi-4 gami, ruwa mai ƙarfi 575℃) don kawar da ƙananan fasa
3. Kula da nakasar nakasa: nakasar gaba ɗaya <0.1mm/m don tabbatar da daidaiton matakin raƙuman milimita

3. Kwatanta aikin lantarki da yanayin aikace-aikace

Halayen radiation:

1.Eriya ta RF: galibi radiation mai jagora, riba ≤10 dBi

2.Eriya ta Microwave: mai matuƙar jagora (faɗin katako 1°-10°), tana samun 15-50 dBi

Aikace-aikace na yau da kullun:

Hasumiyar rediyon FM Sassan T/R na Radar Array da aka tsara a matakai
Na'urori Masu auna IoT Ciyarwar sadarwa ta tauraron dan adam
Alamomin RFID 5G mmWave AAU

4. Bambance-bambancen tabbatar da gwaji

Eriya ta RF:

  1. Mayar da Hankali: Daidaitawar impedance (VSWR < 2.0)
  2. Hanya: Mai nazarin hanyar sadarwa ta vector mai yawan maimaitawa

Eriya ta microwave:

  • Mayar da Hankali: Tsarin haske/daidaiton lokaci
  • Hanya: Duba filin kusa (daidai λ/50), gwajin filin mai ƙanƙanta

Kammalawa: Eriya ta RF ita ce ginshiƙin haɗin mara waya gabaɗaya, yayin da eriya ta microwave ita ce ginshiƙin tsarin mitoci masu yawa da kuma daidaito. Babban abin da ke tsakanin su biyun shine:

1. Ƙaruwar mitar yana haifar da gajarta tsawon tsayi, wanda ke haifar da canjin tsari a cikin ƙira

2. Sauyin tsarin kera kayayyaki - eriya na microwave suna dogara ne akan fasahar zamani kamar injin tsotsa iska don tabbatar da aiki

3. Matsalolin gwaji suna ƙaruwa sosai

Maganin injin tsotsar iska da ƙwararrun kamfanonin tsotsar iska ke bayarwa kamar Solar Atmospheres sun zama babban garanti ga ingancin tsarin raƙuman milimita. Yayin da 6G ke faɗaɗa zuwa ga mitar terahertz, ƙimar wannan tsari za ta fi bayyana.

Don ƙarin koyo game da eriya, da fatan za a ziyarci:
