Broadband High Power Low Insertion Loss Single Directional Loop Couplers
Waveguide loop coupler ke sesebelisoa sa microwave se nang le loop waveguide le mela e 'meli ea phetisetso.
Waveguide coupler e sebelisoa haholo bakeng sa bandpass filteloop le short-circuit impedance impedance bakeng sa mehala ea phetisetso. Coupler ena e ka fetisetsa matla a maqhubu a phahameng ho tloha mothapong o mong oa phetisetso ho ea ho o mong, ka ho etsa joalo e fihlelle ho hokahanya ha beam.
Molao-motheo oa ts'ebetso oa "waveguide loop coupler" haholo-holo o itšetlehile ka likarolo tse peli: litšoaneleho tsa phetisetso ea "loop coupler" le "microstrip line".Directional coupler e bolela ho arola matla ka tsela ea tataiso.
The loop coupler ke karolo ea bohlokoa ho li-waveguide loop couplers, tse bapalang karolo haholo ho kopanya matla.
Khokahano ena ea annular e na le liluu tse peli tse bapileng tse bapileng, 'me halofo e le 'ngoe e sebetsa e le kou ea ho kenya letsoho 'me e 'ngoe e sebetsa joalo ka kou ea tlhahiso. Ha lets'oao la maqhubu a phahameng le fihla ho coupling ea annular haufi le kou ea ho kenya, e tla fetisetsoa ho loop e haufi ea halofo. Nakong ena, ka lebaka la ho ba teng ha matla a khoheli, pontšo e tla boela e fetisetsoe ho loop e 'ngoe ea halofo, kahoo e finyelle ho kopanya matla. Qetellong, hoa khonahala ho kopanya lets'oao la ho kenya letsoho ho tloha boema-kepe ba ho kenya ho ea boema-kepe ba tlhahiso ha o ntse o kenyelletsa tekanyo e phahameng ea ho kopanya hantle.
Matšoao a mantlha a ts'ebetso ea li-couplers tsa loop tse le 'ngoe
Matšoao a mantlha a ts'ebetso bakeng sa li-couplers tsa measuloop tse tataisang li kenyelletsa mofuta oa maqhubu a ts'ebetso, degree ea coupling (kapa transition attenuation), tataiso, le karolelano ea maqhubu a ho kenya / sephetho.
1. Tekanyo ea ho kopanya e bolela karo-karolelano ea decibel ea matla a ho kenya letsoho la waveguide e ka sehloohong ho matla a hlahisoang ke sekepe se kopanyang tlas'a boemo ba mojaro o lekanang boema-kepeng bo bong le bo bong.
2. Tataiso e bua ka tekanyo ea decibel ea matla a hlahisoang ke koung ea ho kopanya ho ea ho matla a tlhahiso ea koung ea ho itšehla thajana tlas'a boemo ba mojaro o ts'oanang le koung ka 'ngoe. Li-couplers tsa Directional li sebelisoa haholo bakeng sa sampole ea matšoao kabong ea matla le tekanyo ea microwave.
Qualwavee fana ka li-broadband le li-couplers tse nang le matla a phahameng a le mong ka mefuta e fapaneng ho tloha ho 2.6 ho isa ho 18GHz. Li-couplers li sebelisoa haholo lits'ebetsong tse ngata.
