Otinga RF auaha i runga i te muka

AuahaRF i runga i te mukaotinga

I roto i te taiao hikohiko e tino uaua haere ana i ēnei rā, me te puta tonu mai o ngā pokanoa tohu, kua noho ko te huarahi ki te whakatutuki i te tuku pono, tawhiti roa, me te pumau o ngā tohu hiko whānui hei wero nui i roto i te mara o te ine me te whakamātautau ahumahi. Ko te hononga whakawhiti whatu whānui RF i runga i te muka anarau he mea auaha tonu.te tuku muka whatuotinga i hangaia hei whakatau i tēnei wero.

Ka tautokohia e tēnei taputapu te kohikohi me te tuku i ngā tohu whānui i te wā tūturu mai i te DC ki te 1GHz, ā, ka taea te whakarerekē ngāwari ki ngā momo taputapu kimi, tae atu ki ngā pūwero iahiko, ngā pūwero ngaohiko teitei me ētahi atu taputapu ine auau teitei. Kei tōna pito tuku he atanga whakauru BNC whakawhiti 1 MΩ/50 Ω, e whakaatu ana i te hototahitanga whānui. I te wā e tukatukahia ana te tohu, ka whakarerekētia ngā tohu hiko ka hurihia hei tohu whatu, ka tukuna ki te pito whiwhi mā roto i ngā muka whatu aratau kotahi, ā, ka whakahokia tika ki ngā tohu hiko taketake e te waeine whiwhi.

He mea tika kia whakahuatia ko te raupapa R-ROFxxxxT e whakauru ana i tētahi tikanga whakahaere taumata aunoa (ALC), e taea ai te ārai i ngā rerekētanga tohu i puta mai i te ngaronga muka, me te whakarite i te mahi pumau i te wā e tuku ana i tawhiti. Hei tāpiri, kei te waeine tuku he attenuator urutau me te whakarite, e tautoko ana i ngā whakatikatika hihiri e toru o te 1:1/10:1/100:1. Mā tēnei ka taea e ngā kaiwhakamahi te arotau i te taumata whiwhinga tohu i runga i ngā horopaki tūturu me te whakawhānui i te whānuitanga hihiri o te pūnaha.

Hei whakatutuki i ngā whakaritenga o te whakamātautau mara, o te whakamātautau pūkoro rānei, ka tautokohia e tēnei raupapa o ngā kōwae te tuku hiko pākahiko me te mana mamao, ā, kei roto hoki he aratau tatari atamai e uru aunoa ana ki te āhua mana iti i ngā wā kāore e whakamahia ana, ka roa ake te ora o te pākahiko o te taputapu. Ka whakaratohia e ngā rama tohu LED i te papa o mua he urupare wā-tūturu mō te āhua whakahaere, ka whakarei ake i te whakahaere me te whai huatanga o te taputapu.

Ahakoa i roto i ngā horopaki pēnei i te aroturuki hiko, te whakamātautau auau reo irirangi, ngā whakamātautau rangahau pūtaiao rānei, ka taea e te raupapa R-ROFxxxxT te whakarato ki ngā kaiwhakamahi i ngā otinga tuku tohu mamao pono, ngāwari, me te tino ārai-whakararuraru.

Whakaahuatanga Hua RF i runga i te muka

Te raupapa R-ROFxxxxTHononga muka RFKo te hononga whakawhiti whatu whānui ā-rorohiko he taputapu tuku mamao muka whatu i hangaia mō te ine wā-tūturu o ngā tohu hiko DC ki te 1GHz i roto i ngā taiao hikohiko uaua. Kei roto i te wae tuku he tāuru BNC 1 MΩ/50 Ω, ka taea te hono atu ki ngā taputapu pūoko rerekē (ngā tirotiro iahiko, ngā tirotiro ngaohiko-tiketike, ngā taputapu ine auau-tiketike motuhake rānei). I roto i te wae tuku, ka whakarerekētia te tohu hiko tāuru ka hurihia hei tohu whatu, ka tukuna ki te wae whiwhi mā te muka whatu aratau-kotahi. Ka hurihia e te wae kaiwhiwhi te tohu whatu hei tohu hiko. Ka whakahaerehia te tuku tohu whatu e te mana taumata aunoa hei pupuri i te mahi tika me te pumau, me te kore e pāngia e te ngaronga whatu. Ka tautokohia e ngā wae whakawhiti e rua te tuku hiko pākahiko me te mana mamao. Kei roto hoki i te wae tuku whatu he attenuator whakarerekētanga urutau (1:1/10:1/100:1) hei whakarerekē i te taumata tohu i whiwhi hei arotau i te whānuitanga hihiri. Hei tāpiri, ina kore te taputapu e whakamahia ana, ka taea te whakauru mamao ki te aratau tatari iti-mana hei penapena mana pākahiko, ā, ka whakaatuhia e te rama tohu LED te mana mahi.
