Kaiwhiwhi HF Homemade mō here runaruna: Kaupapa

E hua farii HF kāinga (ngaru poto) i runga i te pūtake o whakakā resistance. He maha whakarerekētanga ngā waeahia whāurutau me rite rawa ki te amplifiers. ara iahiko stabilizer Paerewa he auau teitei. Hei whakatika i te faders teihana ki e whakamahia Pads.

Me mahara hoki käore te reira e he rerekē i ia atu i roto i te kawe ia, me te auau tetrode te farii. I roto i te tikanga ki te pai te mahi ki tenei take, me whakaaro tatou farii tino rongonui o te kaupapa.

pūrere auau iti

Scheme improvised HF kaiwhiwhi auau iti ngā te modulator controllable, me te huinga o ngā pūnga. E whiriwhiria parenga mo te pūrere 4 PF. He maha ngā tauira i te transistors whakapā, e mahi ana i te transducers. Me mahara hoki käore te reira e Kei roto i te ara iahiko kaiwhiwhi transceivers anake pou.

Hoki hongere tono tautuhinga mana e kua tāuta i te timatanga o te mekameka. E hanga ētahi tauira ki tetahi anake whāurutau, a mono ratou i raro i te momo rārangi i tīpakohia. Ki te whakaaro tatou he tauira ohie, whakamahia ratou mātiti mana. Mahi i te reira i te auau o 400 MHz. E tāuta insulators mō modulators.

tauira auau teitei Tube

ngongo Homemade auau teitei farii HF ngā pūoko whakapā me foaki ki kawe ia iti. korero pai ētahi tohunga e pā ana ki enei whakaaro. Tuatahi o te katoa, mōhio ratou i te kaha ki te tūhono transceivers. Pāngia e raro i tika momo whakarerekē ITR. Nuinga o ngā wā i reira he whakaaro ki parenga Semiconductor.

Ki te whakaaro tatou ki te kaupapa paerewa, kua he momo whakarite i te comparator. E tāuta parenga i te putanga ki te kaha o kore iti iho i te 3.4 PF. E kore te te kawe ia tuku iho i raro 5 microns. eke te regulator i runga i toru ranei wha takere. I roto i te nuinga o farii, kotahi anake tātari wāhanga.

whakarerekē he pini

He pini kaiwhiwhi HF kāinga mō ngā here runaruna taea o mahi i te auau o 300 MHz. E tapiritia nuinga tauira ki te tara titi. I roto i ētahi wā, te whakamahi i transceivers. Sensitization o parenga tei runga i te kawe ia. Te puritanga he rite ki te 3 PF i te putanga.

contactors kawe toharite o 6 microns. E hua te nuinga farii ki te whāurutau dipole, e he tika ana mō tūhono PP. Tino maha i reira he wae condenser, e mahi i runga i te thyristors. Ki te whakaaro tatou ki te tauira o te rama, he mea nui ki te mōhio e whakamahia ratou unijunction comparators. E whakaurua ratou anake i te auau o 300 MHz. Ano, me ahau mea ai ki reira he tauira ki transistor.

Ko te whakaaro kotahi-pou

Ko reira ohie ki te whakaturia ake, kotahi-ngongo farii HF whaiaro-hanga. Ona ringa haere tauira ki comparators tāupe. E hangaia te nuinga o nga whakarerekētanga ki stabilizers kawe ia iti. ara iahiko kaiwhiwhi Paerewa whai wāhi te whakamahi o parenga dipole nei putanga te puritanga ōrite 4.5 PF. pea te kawe ia ki runga ki te 50 microns.

Ki te takitahi kohikohi koe whakarerekētanga, Me te comparator ki kotinga ki te transceiver. E soldered nga parenga i ki te modulator. huānga Ātete, rite ki te tikanga, e kore e nui ake 45 ohms, engari i reira he okotahi. Ki te kōrero tatou e pā ana ki te farii i runga i te tānga, kua ratou e whakamahia transistors te whakarite. Mahi huānga raraunga i te modulator, a rerekē ratou i roto i te tūtohutanga.

Hanga farii maha-pou

He aha painga e te kaiwhiwhi HF pūoko maha-pou i runga i nga here runaruna? Ki te whakapono arotake tohunga, enei whakaaro hoatu auau tiketike, me te pau te kupu iti hiko. Kei te haere te nuinga o whakarerekētanga ki dipole contactors me whāurutau whakamahia momo waea. He pai mō ngā akomanga rerekē nga tūhono.

Kei roto ngā tātari wāhanga e whakaiti i te mōrea o te kore o te raweketia poipoi ētahi tauira. Me mahara hoki käore te reira e te kaupapa mana paerewa tā te whakamahi o te kaiwhakahaere ki te whakatika i te auau. Comparators i roto i ētahi wā i reira he momo hongere. A, no te whakamahia tenei transistor te ki kotahi anake isolator, me kawe ia ko reira kore i raro i 45 microns. Ki te whakaaro tatou nga expanders farii, e taea ki te mahi anake i iarere iti ratou.

Tauira ki te dvuhperehodnym pūtahuri

E nehenehe o stably te pupuri i te auau i 400 MHz farii HF mō here runaruna ki pūtahuri dvuhperehodnymi. whakamahi maha tauira i te pou zener. mahi ia i te transducer me he kawe ia tiketike. Paerewa akatuke'anga iahiko ngā he pūmana mō te toru putanga me te pūnga. he pai hoki tauira ki varicap te tīwerawera.

Me mahara hoki käore te reira e taea te pai fekuki te pūrere inverter nui-auau o tenei momo ki ngangau hihiko i te kōwae. E whakamahia Comparators ki mātiti me capacitive pūparenga. ātete Tawhā i runga i te tāuru ara iahiko, ko te rite ki te pā ana ki 45 ohms. I roto i tenei take, ka taea e te tūtohutanga kaiwhiwhi kia tino rerekē.

he whakaaro pūtahuri e toru-waea

kaiwhiwhi HF Homemade mō here runaruna ki te kaitahuri toru-waea kua he contactor kotahi. E whakamahia Tūhono ki te paraharaha, kahore reira. Me mahara hoki käore te reira e whakamahia nga parenga kawe ia rerekē. I te timatanga o te mekameka reira ko te huānga 3 microns. Te reira i te tikanga pā momo unipolar me haere nāianei i roto i te ahunga kotahi anake. Kei te condenser te muri reira ki te pēne rārangi.

Me mahara hoki käore te reira e te parenga i te putanga o te ara iahiko i kawe ia iti. I roto i te farii maha e whakamahia momo tāupe a taea whakahaere o nāianei i roto i ngā tohutohu e rua. Ki te whakaaro tatou te whakarerekē i 340 MHz, ka taea e ratou te whakatau ki triodes comparators mātiti. mahi ratou ki te ātete nui haere, me te ngaohiko ko rite nui rite 24 V.

Whakarerekētanga ki te 200 MHz

Ko te tino noa kaiwhiwhi HF kāinga mō ngā here runaruna ki te auautanga 200 MHz. Tuatahi o te katoa kia tuhia te reira e kore e taea e ki te mahi i runga i te comparators nga tauira. te tupu pinepine akatuke'anga rārangi. Heoi, whakaaro te whakaaro tino noa te ki te waiho i te decoders tauira whakawhitinga. E tāuta ana ratou ki te huinga o whāurutau. E whakamahia parenga i te timatanga o te mekameka o te kaha nui, me te ātete i ratou i te iti rawa rite ki te 55 ohms.

Amplifiers te whakatau ki whiriwhiringa me kahore ratou. Ki te whakaaro tatou ki te whakarerekē haora, ka Matarua ratou e whakamahia pūnga iahiko. I roto i tenei take, whakamahia te stabilizer e ki te regulator. Hei whakatika i hiahiatia te modulator hongere te. Ētahi farii mahi ki farii. E ratou he raupapa o tūhono PP.

Pūrere 300 MHz

kaiwhiwhi HF Homemade mō here runaruna ki te auautanga 300 MHz ngā rua o parenga takirua. Comparators mō tauira te whakatau ki te kawe ia o 40 microns. Ētahi whakarerekētanga ngā expanders waeahia. Ēnei āhuatanga e taea tino offloads te pūnga iahiko.

Ki te whakapono koe whakaaro nga tohunga ', nga tauira o tenei momo he hypersensitivity taiea. pūrere Homemade hanga kahore Tetrodes. Hei whakapai ake i tohu āriponga te tono transistors anake. Me mahara hoki käore te reira e reira e whakaaro ki te whiriwhiringa hongere.

Whakarerekētanga ki te 400 MHz

Taraiwa pūrere i 400 MHz riro tono whāurutau dipole me te whatunga o pūparenga. Transceiver, whakamahia te tauira te ki te whakatuwhera i te tātari. Ki te huihui i te pūrere ki o koutou ringa, matua hauhake tetrode. podirayutsya pūnga iahiko i raro i taua mea kawe ia iti me te tūtohutanga o 5 mV. Me mahara hoki käore te reira e e whakaaro nga whakaaro noa farii iti-auau pērā i transformers. I tua atu, i roto i te tikanga ki te kohikohi i te pūrere ki o koutou ringa, tango kotahi modulator. Eke i roto i te mua o te transducer huānga kaha.

Tube pūrere tairongo iti

Tube HF kaiwhiwhi mō here runaruna kiriuka taea ki te mahi i runga i hongere rerekē. Ko te hoahoa paerewa o te pūrere tā te whakamahi o te stabilizer. A, no te whakamahia tenei whāurutau te tuwhera. Me kia te kawe ia o te parenga i te iti rawa 55 microns. He mea nui hoki ki te mōhio e kua hanga nga farii ki mau api. Ki te huihui i te pūrere ki o koutou ringa, mahi he huinga o ngā pūnga. Raukaha hiahiatia ratou ki kia i te iti rawa 45 PF. Wehe, he mea nui ki te mōhio e whakanuia nga farii o tenei momo i te aroaro o whāurutau Matarua.

farii tairongo tiketike

mahi pūrere tūtohutanga tiketike i te auau o 300 MHz. Ki te whakaaro tatou he tauira ohie, kua kohia ai i runga i te pūtake o te comparator ki te kawe ia o 4 microns. I roto i tenei take, whakaaetia nga whiriwhiringa e ki te whakamahi i te reira i raro i te paraharaha tuarua.

Transistors unijunction te momo kaiwhiwhi i whakaritea, me te tātari whakamahia mō te 4 PF. Tino maha waeahia transceivers. E ratou kawe ia pai, me te kore e rapu utu i te rota o te pūngao.

kia anake te whakamahi i te modulator ki kotahi varicap. Ko te kupu, e taea ki te mahi i runga i takere rerekē te tauira, ko te. Hei whakaoti i te raruraru ki te ātete tōraro te whakamahi i te roha puritanga.
