1 He Med e pa ana ki te whakakino i te modulator whakahekeheke. Ko te ōwehenga ngaro kua tutuki ko te nuinga o te reanga ngaro o te kaiwhakaputa i tohua i roto i te kaiwhakaari o Datasheet.

1 Ko te polar e whakawhirinaki ana ki te tohu RF. Mena kaore he tohu RF i roto i te punaha, me whai hua te polar. I te wa e nui ake ana te tohu RF i tetahi taumata, ka huri te polar mai i te pai ki te kino. I tenei wa, ka huri te tohu o te tohu me te tihi. Q + tohu me te Q- tohu ka huri tahi me a raatau ano. Ko te huringa polar e whakahohe ana i te kaiwhakamahi ki te whakarereke i te
Polar tika tonu me te kore e whakarereke i nga tohu whakahaere.

1 Kotahi noa iho te whiringa ka tohua i waenga i te whakaahua kaiwhakahaere, ki te whakamahi i te kaiwhakamahara ranei. E taunaki ana kia whakamahia te whakaahua kaiwhakahaere mo nga whakamatautau taiwhanga mo nga take e rua. Tuatahi, kua whakatauhia e te Kaimanaaki te kounga o te Kaituku. Tuarua, he ngawari ake te whakatika i te kaha o te kaha. Mena kei te whakamahi i te Whakaahuatanga o Modulator, tena koa kia pai te whakaputa o te PhotodioDe ki te mana whakauru.
Ko Rofea Optoelectronics te raina hua o nga kaiwhakaora-arotau, nga kaiwhakaari kaha, nga whakaahua a laser, te miihini optical. laser, te laser laser, te kaimau optical, te taraiwa laser diode, ka whakanuia te muka. Ka whakaratohia ano hoki e matou etahi atu modulate motuhake mo te whakarite, penei i te 1 * 4 Whakapaipai i nga kaiwhakatakoto tohu, me te miihini nui o te ultra-teitei, me te whare wananga.
Ko te tumanako ka awhina a maatau hua ki a koe me o mahi rangahau.
