Receiver HP ekhaya ngenxa bands engahlawulwayo: Scheme

balwamkele HP ekhaya (amaza ezimfutshane) ziveliswa ngokusekelwe itshintshela ukuxhathisa. Izilungiso ezininzi ziquka igxunyekwe iadaptha kwaye ifakwe yokukhulisa. circuit somfanekiso Standard iye frequency ephakamileyo. Ukuze ulungise faders siteshi ukuba pads zisetyenziswa.

Kufuneka kuqatshelwe ukuba balwamkele zahlukile enye kwenye conductivity namatyeli tetrode. Ukuze ikwazi ukujongana kakuhle kulo mba, kufuneka sijonge ukuba balwamkele idumileyo icebo likaThixo.

izixhobo njalo

Scheme ngcono HP receiver njalo iquka modulator controllable, kunye uluhlu capacitors. Resistors abakhethelwe isixhobo 4 PF. imifuziselo abaninzi transistors umfowunelwa, apho asebenza ukususela transducers. Kufuneka kuqatshelwe ukuba zeesekethe receiver yenziwa kuphela transceiver ipali.

Kuba channel Izicwangciso ukusebenzisa ulawulo ukuba zifakelwe ekuqaleni kwikhonkco. Ezinye iimodeli zenziwa kunye iadaptha omnye kuphela, uzifake phantsi uhlobo umgca olukhethiweyo. Xa siqwalasela imodeli elula, basebenzisa amandla igridi. It basebenzisa rhoqo 400 MHz e. Insulators zifakwa ngenxa modulators.

Tube pattern aqhelelkileyo

tube ekhaya aqhelelkileyo HF balwamkele ziquka abenzi zoqhagamshelwano kunye zidlulisele kunye conductivity eliphantsi. Ezinye iingcali bathetha kakuhle ezi zixhobo. Kuqala kwinto zonke, baya qaphela ubuchule ukudibanisa transceiver. Ekwenyukeni phantsi ezifanelekileyo uhlobo loguqulelo ITR. Amaninzi kukho izixhobo kunye resistors semiconductor.

Ukuba sicinga scheme yebakala, comparator ine uhlobo adjustable. Resistors zifakwa ngamashishini enesakhono ongekho ngaphantsi kwe-3.4 PF. Le conductivity ke abawathobanga ngezantsi microns-5. Umlawuli ukhwele amajelo ezintathu okanye ezine. Xa balwamkele ezininzi, omnye kuphela kwisigaba lokucoca ulwelo.

ukubetha ukuguqulwa

Imifino receiver HP ekhaya ngenxa bands engahlawulwayo esikwaziyo eqhuba rhoqo 300 MHz e. Imifanekiso ziyongezwa kwi-amaphiko pin. Kwezinye iimeko, esebenzisa transceiver. Zegazi of resistors kuxhomekeke conductivity. Capacitance kwi imveliso ilingana 3 PF.

contactors Conductivity avareji microns 6. Uninzi balwamkele ziveliswa kunye ezisebenza ngokubakho dipole, afaneleka izihlanganisi PP. Amaxesha amaninzi kukho iiyunithi ekondensa, apho asebenza kwi thyristors. Ukuba sicinga imodeli izibane, kubalulekile ukuqaphela ukuba asebenzisa unijunction comparators. Ziyabandakanywa kumaza ka 300 MHz kuphela. Kwakhona, ndiya kuthi ukuba kukho onobuhle transistor.

Zizixhobo-kwipali eyodwa

Kulula ukuba kumisa, single-ityhubhu balwamkele HF self-eyenziwe. Izandla zakhe ongumzekelo comparators variable khona. Uninzi iinguqulelo zilungiselelwe kunye ekwenzeni conductivity eliphantsi. circuit receiver Standard lubandakanya ukusetyenziswa resistors dipole capacitance kabani output ilingana no 4.5 PF. Le conductivity singaba microns 50.

Ukuba ngokuzimeleyo ukuqokelela ukuguqulwa, lo comparator kufuneka ukuvuna kunye transceiver. Le resistors ke soldered kwi ukuya modulator. izinto Resistance, njengoko umthetho, ayidluli ohms 45, kodwa ke kukho iimeko. Ukuba sithethe abaphiwa kwi relay, baye transistors adjustable zisetyenziswa. Sebenza izinto data evela modulator, yaye zahluke uvakalelo.

Ukwakha balwamkele multi-pole

Ziziphi iingenelo wenza multi-pole kakutsha HF ufumana kwi engahlawulwayo bands? Ukuba reviews iingcali zikholelwa, ezi zixhobo ukunika rhoqo eliphezulu kwaye oko kudla umbane omncinane. Uninzi zokuguqulwa ukuti dipole contactors kunye ezisebenza ngokubakho kusetyenziswa uhlobo wire. Ezi izihlanganisi ezilungele kwiiklasi ezahlukeneyo.

Eminye imizekelo ziqulathe okucoca sigaba zokunciphisa umngcipheko yokusilela sokuphamazisa otshangatshangiswayo. Kufuneka kuqatshelwe ukuba inkqubo yolawulo olusezantsi lubandakanya ukusetyenziswa umlawuli ukunyenyisa rhoqo. Comparators kwezinye iimeko kukho uhlobo channel. Xa oku transistor isetyenziswa ne isolator omnye kuphela, kwaye conductivity alithe kwe 45 microns. Ukuba sicinga wegazi balwamkele, ukuba akwazi ukusebenza kuphela ezitsho eliphantsi.

Onobuhle dvuhperehodnym yokuguqula

balwamkele HP for bands engahlawulwayo kunye converters dvuhperehodnymi bayakwazi stably ukugcina ifrikwensi 400 MHz. imifuziselo abaninzi basebenzisa ipali zener. Usebenza ukusuka transducer kwaye conductivity eliphezulu. Standard iinguqulelo kancinane beesekethe iquka umlawuli ukwenzela iimveliso ezintathu kunye capacitor. Lo mshini ilungele ukuba uhle varicap.

Kufuneka kuqatshelwe ukuba isixhobo inverter ophezulu rhoqo olu hlobo unako kakuhle ukumelana ingxolo angxamele ukusuka unit. Comparators zisetyenziswa kunye igridi kunye capacitive resistors. ukumelana Ipharamitha kwigalelo yesekethe ulingana ohms malunga 45. Kulo mzekelo, inovakalelo umamkeli yahluke kakhulu.

locingo emithathu-izixhobo lokuguqulela

Ekhaya HP receiver ukuba amaqela engahlawulwayo kunye ngocingo ezintathu-converter unalo lwekontraka enye. Izihlanganisi zisetyenziselwa elibonakayo ngaphandle kwayo. Kufuneka kuqatshelwe ukuba resistors kusetyenziswa conductivity ezahlukeneyo. Ekuqaleni chain kukho into 3 microns. Isebenza ngokubanzi uhlobo unipolar, wegqitha ngoku kwicala elinye kuphela. Le ekondensa ibekwe ngasemva kulo umqhubi yomgama.

Kufuneka kuqatshelwe ukuba resistor xa imveliso yaloo mmandla babe conductivity eliphantsi. Xa balwamkele amaninzi asetyenziswa uhlobo bume kwaye baqhube ngoku kumacala omabini. Xa siqwalasela ukuguqulwa kwi 340 MHz, ngoko ke uhlangana triodes comparators kwegridi. Zisebenza kunye ukuxhathisa anda, kwaye ombane kuba kangangoko 24 V.

Zokuguqulwa 200 MHz

Ekhaya HP receiver for bands engahlawulwayo nge frequency 200 MHz kuqhelekile kakhulu. Okokuqala kufanele kuqatshelwe ukuba imifuziselo bengakwazi ukusebenza kwi comparators. Izilungiso yomgama akholisa ukubakho. Noko ke, iingcinga zixhaphakileyo kuthathwa ukuba STB umfuziselo yenguqu. Bona efakwe neqela ezisebenza ngokubakho. Resistors ekuqaleni abaphathi-amandla aphezulu asetyenziswa, yaye ukuxhathisa babe ohms kwi ngokulinganayo ubuncinane ku-55.

Yokukhulisa ukudibana lwamacebo okucoca ngaphandle kwazo. Ukuba sicinga ukuguqulwa yokucofa, ngoko ke untlu capacitors zisetyenziswa. Kulo mzekelo, i somfanekiso lisetyenziswa kuMgqaliseli. Ukunyenyisa modulator ijelo iyafuneka. Ezinye balwamkele asebenza kunye balwamkele. Bona babe uthotho PP isinxibelelanisi.

Devices MHz 300

Ekhaya HP receiver for bands engahlawulwayo nge frequency 300 MHz kuquka ngambini kuzo resistors. Comparators njengezibonelo udibana nomntu conductivity of microns 40. Ezinye iinguqulelo ziquka wegazi igxunyekwe. Ezi zinto azikwazi offloads kakhulu capacitors.

Ukuba uyakholwa uluvo ziingcali, imifuziselo elolu hlobo hypersensitivity ebalaseleyo netshatsheleyo. isixhobo ekhaya ezenziwe ngaphandle Tetrodes. Ukuphucula uphawu Uhanjiso isicelo transistors kuphela. Kufuneka kuqatshelwe ukuba kukho izixhobo kunye amacebo channel.

Zokuguqulwa 400 MHz

isixhobo ibihamba MHz 400 angenela isicelo dipole iadaptha kunye uthungelwano resistors. Transceiver, imodeli isetyenziselwa ukuvula lokucoca ulwelo. Ukuba bahlanganise isixhobo ngezandla zenu, ikakhulu ukuvunwa tetrode. Capacitors ngaphantsi kwalo podirayutsya conductivity ephantsi nobuntununtunu 5 MV. Kufuneka kuqatshelwe ukuba izixhobo eziqhelekileyo zijongwa balwamkele ezisezantsi rhoqo ezifana abaguquli. Ngaphezu koko, ukuze aqokelele isixhobo ngezandla zenu, ukuthatha modulator omnye. Onyuswe phambi transducer into esebenzayo.

Tube Izixhobo Uvakalelo oluphantsi

Tube HP receiver for bands engahlawulwayo buthuntu kukwazi ukuba usebenzise iindlela ezahlukeneyo. Lo mzobo ibhanile isixhobo kubandakanya ukusetyenziswa somfanekiso. Xa oku iadaptha lisetyenziswa evulekileyo. Le conductivity le resistor kufuneka microns ubuncinane 55. Kubalulekile ukuba uqaphele ukuba balwamkele benziwa amacwecwe. Ukuba bahlanganise isixhobo ngezandla zenu, wabafunela iseti capacitors. ke amandla kufuneka babe 45 ubuncinane PF. Ngokwahlukeneyo, kubalulekile ukuqaphela ukuba bathunyelwa olu hlobo ahluka bubukho amaqhoshana engayi.

balwamkele uvakalelo oluphezulu

isixhobo eliphezulu ubuzaza basebenzisa rhoqo 300 MHz e. Xa siqwalasela imodeli elula, oko iqokelelwa ngokususela comparator kunye conductivity of microns 4. Kulo mzekelo, isihluzo esinye bavumelekile ukuba basebenzise phantsi kwipleyiti yesibini.

Transistors unijunction uhlobo receiver iseti kunye amacebo asetyenziswa 4 PF. Lidla igxunyekwe transceiver. Baye conductivity elungileyo kwaye musa ukuba amandla amaninzi.

Le modulator lungasetyenziswa kuphela varicap mnye. Ngenxa yoko, le modeli uyakwazi ukuba usebenzise iindlela ezahlukeneyo. Ukusombulula iingxaki kunye nokumelana ezimbi usebenzisa ukwanda capacitor.
