Broadband High Power Low Selipan Mundhut Dual Directional Loop Couplers
Dual directional loop coupler minangka piranti gelombang mikro terintegrasi sing ngidini transmisi efisien lan kopling sinyal ing macem-macem pandu gelombang.
Secara khusus, coupler loop arah ganda dumadi saka pandu gelombang bunder lan pandu gelombang ganda. Kanthi nyetel kekuatan kopling antarane kopling.
Waveguide lan waveguide daur ulang, transmisi arah energi antarane pandu gelombang beda bisa digayuh. Komponen inti saka coupler loop arah yaiku blok dielektrik bunder, biasane dumadi saka blok tubular utawa sheet-like, kanthi garis mikrostrip bunder ing jero blok kasebut. Nalika sinyal frekuensi dhuwur lumebu ing pemblokiran dielektrik annular saka salah siji saka bandar, bakal mboko sithik nransfer sadawane dalan bunder ing wektu cendhak lan pungkasanipun bakal mbagekke menyang bandar liyane. Sajrone proses transfer, amarga karakteristik resonansi blok dielektrik lan jalur tetep sirkuit, prabédan shift fase dijaga watara 90 derajat, entuk distribusi daya sing tepat.
Aplikasi:
Coupler puteran arah ganda digunakake ing komunikasi gelombang mikro, sistem radar, komunikasi satelit, susunan antena, lan lapangan liyane. Ing antarane, aplikasi ing sistem komunikasi nirkabel utamane ekstensif, kayata 3G, 4G, jaringan komunikasi seluler 5G lan jaringan WLAN, uga deteksi radar lan televisi penyiaran.
ciri:
Dibandhingake karo coupler arah 180 derajat tradisional, coupler puteran arah duwe kaluwihan kayata bandwidth sing luwih akeh, kerugian sing luwih murah, volume lan massa sing luwih cilik, lan manufaktur lan integrasi sing luwih gampang. Kerugian yaiku kontrol presisi sing dhuwur dibutuhake sajrone proses manufaktur, lan bisa uga ana masalah kayata ketidakseimbangan fase lan fluktuasi daya sajrone operasi. Mulane, desain lan ukuran khusus dibutuhake kanggo pangaturan lan ganti rugi.
Qualwavenyuplai broadband lan daya dhuwur dual directional couplers daur ulang ing sawetara saka sudhut 1,72 kanggo 12,55GHz. Coupler digunakake kanthi akeh ing akeh aplikasi.
