Igwe Ngwakọta IQ RF Mikrowev Millimeta Wave Elu Igwe Ngwakọta Redio Ugboro Elu
Ngwakọta Ngwakọta Ngwakọta Ngwakọta Ngwakọta bụ ụdị igwekota pụrụ iche nke nwere ụzọ mgbaama usoro abụọ na-arụkọ ọrụ nke a na-akpọ "In-phase" (I) na "Quadrature" (Q). Ihe ndị e ji mara ya bụ ndị a:
1. Nye ozi gbasara usoro na oke olu: N'ihi itinye ọwa I na Q, igwekota IQ ugboro redio nwere ike inye ma ozi gbasara usoro na oke olu nke mgbaàmà ahụ. Nke a dị mkpa maka ọtụtụ sistemụ nkwukọrịta ikuku na usoro nhazi na mwepụ.
2. Mara nhazi mgbaama orthogonal: Ọwa I na Q nke igwekota RF nwere ike ịhazi mgbaama orthogonal, ya bụ, mgbaama nwere ọdịiche nke usoro nke ogo 90. Nke a na-eme ka igwekota ugboro redio bara uru nke ukwuu n'ọtụtụ usoro modulation na demodulation, dịka orthogonal frequency division multiple access (OFDM) na quadrature amplitude modulation (QAM).
3. Mbelata nnyonye anya: Ngwakọta IQ nwere ike ikewapụ nnyonye anya na nnyonye anya n'ihi na etinyere ụzọ abụọ na-emekọ ihe ọnụ. Nke a na-eme ka ọ nwee ike imeri nnyonye anya na-ege ntị.
4. Oke ike dị elu: N'ihi ojiji nke ọwa abụọ, igwekota IQ na-enwekarị oke ike dị elu nke nwere ike izute ngwa nhazi mgbaàmà siri ike.
A na-ejikarị IQ mixer eme ihe n'ọtụtụ akụkụ ndị a:
1. Sistemụ nkwukọrịta ikuku: A na-ejikarị igwekota ebili millimeter eme ihe na sistemụ nkwukọrịta ikuku, gụnyere sistemụ nkwukọrịta mkpanaka, sistemụ nkwukọrịta satịlaịtị na netwọk mpaghara ikuku. A na-eji ya eme ka akara anata dị mfe, gbanwee akara ezigara, ma mezuo mgbanwe, mgbanwe na mgbanwe ugboro ugboro nke akara ahụ.
2. Modem: Ngwakọta IQ bụ isi ihe ndị a na-ahụkarị na modem ndị a na-eji agwakọta akara baseband n'ime oke RF maka nnyefe, ma ọ bụ iji gwakọta akara RF enwetara na baseband maka demodulation.
3. Nzipu data ọsọ ọsọ: Ebe ọ bụ na igwekota IQ nwere ike ijikwa akara orthogonal, ha nwere ngwa dị mkpa na nnyefe data ọsọ ọsọ. Dịka ọmụmaatụ, na sistemụ nkwukọrịta anya na nkwukọrịta dijitalụ ọsọ ọsọ, nhazi QAM na demodulation site na iji igwekota IQ nwere ike ime ka nnyefe data ọsọ ọsọ na ikike dị elu.
4. Nyocha nke ndị na-ebu ibu: Enwere ike iji ihe ndị na-agwakọta IQ mee nyocha nke ndị na-ebu ibu, nke nwere ike inyere aka chọpụta ebe nnyonye anya si apụta ma wepụ nnyonye anya site n'ịtụle na inyocha ozi nke usoro na oke nke mgbaàmà ahụ.
