1. Nye usoro na njupụta ozi: N'ihi nsonye nke I na Q ọwa, IQ igwekota nwere ike inye ma na-adọ na amplitude ozi nke mgbaàmà. Nke a dị mkpa maka ọtụtụ usoro nkwurịta okwu ikuku na usoro modulation na demodulation.
2. Ghọta nhazi akara ngosi orthogonal: Ọwa I na Q nke igwekota IQ nwere ike ịhazi akara ngosi orthogonal, ya bụ, akara nwere ọdịiche dị iche iche nke ogo 90. Nke a na-eme ka ọ baa uru nke ukwuu n'ọtụtụ usoro modulation na demodulation, dị ka orthogonal ugboro nkewa multiple ohere (OFDM) na quadrature amplitude modulation (QAM).
3. Mbelata nnyonye anya ige ntị: Onye na-agwakọta IQ nwere ike ikewa akara ngosi na nnyonye anya ụdịdị dị iche iche n'ihi ntinye nke ụzọ abụọ na-akwado. Nke a na-eme ka ọ nwekwuo ike igbochi nnyonye anya ntị.
4. High ike nso: N'ihi na ojiji nke abụọ ọwa, IQ mixers a na-enwe a elu ike nso nke nwere ike izute-achọsi ike nhazi ngwa.
1.Wireless nkwurịta okwu usoro: IQ igwekota ọtụtụ-eji wireless nkwurịta okwu usoro, gụnyere mobile nkwurịta okwu usoro, satellite nkwurịta okwu usoro na wireless mpaghara netwọk. A na-eji ya mee ka akara ngosi natara, gbanwee akara ngosi ezigara, ma ghọta ngbanwe, mgbanwe mgbanwe na ugboro ugboro nke mgbaàmà.
2.Modem: Ngwakọta IQ bụ isi ihe ndị a na-ahụkarị na modem nke a na-eji agwakọta akara ngosi baseband n'ime oke RF maka nnyefe, ma ọ bụ ijikọ akara RF natara n'ime baseband maka demodulation.
3.High-speed data nnyefe: N'ihi IQ mixers nwere ike ijikwa orthogonal akara, ha nwere mkpa ngwa na elu-ọsọ data nnyefe. Dịka ọmụmaatụ, na usoro nkwurịta okwu ngwa anya na nkwukọrịta dijitalụ dị elu, QAM modulation na demodulation site na iji mixers IQ nwere ike ime ka nnyefe data dị elu na nke dị elu.
4.Carrier nnyonye anya nyocha: IQ mixers nwere ike iji maka nyocha nnyonye anya ụgbọelu, nke nwere ike inyere aka chọpụta isi iyi nke nnyonye anya ma wepụ nnyonye anya site na ịlele na nyochaa oge na ozi njupụta nke mgbaàmà.
