Ngwaọrụ Na-anaghị Eme Ihe Maka Mgbasa Ozi RF
1. Ọrụ nke ngwaọrụ okirikiri RF
Ngwaọrụ mgbasa ozi RF bụ ngwaọrụ ọdụ ụgbọ mmiri atọ nwere njirimara nnyefe otu ụzọ, na-egosi na ngwaọrụ ahụ na-eduzi site na 1 ruo 2, site na 2 ruo 3, na site na 3 ruo 1, ebe a na-ekewapụ mgbaàmà ahụ site na 2 ruo 1, site na 3 ruo 2, na site na 1 ruo 3. Ịgbanwe ntụziaka nke ubi ferrite bias nwere ike ịgbanwe ntụziaka nke nnyefe mgbaàmà, enwere ike iji ibu dakọtara dị ka ihe na-ekewapụ n'otu nsọtụ nke mgbasa ozi RF.
Mgbasa ozi RF na-arụ ọrụ na nnyefe mgbaàmà ntụziaka na nnyefe duplex na sistemụ, a pụkwara iji ya na sistemụ radar/nkwukọrịta iji kewapụ akara nnata/nnyefe n'etiti onwe ha. Mgbasa ozi na nnata nwere ike ịkekọrịta otu antenna ahụ.

2. Nhazi nke RF Circulator
Ụkpụrụ nke ngwaọrụ RF Circulator bụ ịkpa ókè n'ihe ndị e ji ferrite mee site na iji magnetik. Site n'iji mmetụta ntụgharị Faraday nke ụgbọelu polarization na-agbagharị mgbe ebili mmiri electromagnetic na-ebufe na ihe ferrite na-agbagharị agbagharị nwere oghere magnet DC mpụga, site na nhazi kwesịrị ekwesị, oghere polarization nke ebili mmiri electromagnetic na-adabere na plọg resistive grounded n'oge nnyefe gaa n'ihu, na-ebute obere mbelata. Na nnyefe azụ, oghere polarization nke ebili mmiri electromagnetic dị ka plọg resistive ground ma fọrọ nke nta ka ọ banye kpamkpam. Nhazi microwave gụnyere microstrip, waveguide, strip line, na ụdị coaxial, nke microstrip atọ terminal circulations bụ nke a na-ejikarị eme ihe. A na-eji ihe Ferrite eme ihe dị ka ihe etiti, a na-etinyekwa nhazi band conduction n'elu, yana mgbakwunye na magnetik na-adịgide adịgide, iji nweta njirimara circulation. Ọ bụrụ na agbanwee ntụziaka nke ubi magnetik bias, ntụziaka nke loop ga-agbanwe.
