Maseketi emagetsi amplifier anoita basa rakakosha mune zvisingaverengeki zvigadzirwa zvemagetsi, kubva mumhanzi amplifiers kuenda kune transmitters.Kunzwisisa maitiro avo uye mabasa makuru kwakakosha kune chero zvemagetsi hobbyist kana nyanzvi.Mune ino blog, isu tichaongorora nyika inonakidza yemagetsi amplifier maseketi, tichiongorora iwo makuru maficha, misimboti yekushanda, uye mashandisiro.Saka kunyangwe iwe uri mudzidzi anoda kuziva kana injinjiniya anoda, simuka apo isu tinotanga rwendo rwuno zvine hungwaru.
Chii chinonzi simba amplifier circuit?
Tisati tanyatsoongorora maitiro avo, ngatitangei tatsanangura zvatiri kureva nemagetsi amplifier circuit.Zvichitaurwa zviri nyore, dunhu remagetsi amplifier idunhu remagetsi rinosimudzira masaini emagetsi kusvika padanho repamusoro remagetsi akakodzera kutyaira mutoro, semutauri kana antenna.Kazhinji, magetsi amplifier maseketi anotora yakaderera-level odhiyo kana redhiyo frequency yekuisa siginecha uye inoikudza zvakanyanya kuti ipe simba rinodiwa kune yakarongwa application.
Simba amplifier redunhu maitiro
1. Simba rekubata masimba: Simba amplifier circuits rakagadzirirwa kubata mazinga epamusoro emagetsi kana achienzaniswa nemamwe marudzi emagetsi.Kugona kwavo kuendesa simba rakakura kunoita kuti vakwanise kutyaira mitoro inodiwa zvakanaka uye nekuvimbika.
2. Linearity: Magetsi emagetsi anoedza kuchengetedza nemazvo chimiro uye ruzivo rwechiratidzo chekuisa.Linearity yakakosha kudzikisa kukanganisa uye kuve nechokwadi kubereka kwakatendeka kwechiratidzo chepakutanga.
3. Kunyatsoshanda: Kunyatsoita chinhu chakakosha kufunga mumaseketi emagetsi amplifier nekuti inosarudza kushandurwa kwesimba remagetsi kuita simba rinobuda rinobatsira.High-effective power amplifiers inoderedza kupera kwesimba, nekudaro kuderedza kushandiswa kwebhatiri uye kupisa kupisa.
4. Bandwidth: Iyo bandwidth yemagetsi amplifier wedunhu inoreva kune frequency renji iyo inogona kukwirisa nekutendeka.Zvichienderana nekushandiswa, magetsi amplifiers anogona kuverengerwa seaudio simba amplifiers anoshanda muredhiyo renji, kana redhiyo frequency magetsi amplifiers anoshandiswa mumatambo ekutaurirana asina waya.
Mabasa makuru emagetsi amplifier circuit
+Masimba amplifiers anochengetedza kutendeka uye mhando yechiratidzo chekupinza ichipa simba rakakwana rekutyaira mutoro.
2. Impedance matching: Maseketi emagetsi amplifier anowanzo kuve ane impedance yekufananidza network kuti iwedzere simba rekufambisa pakati peamplifier uye mutoro.Izvi zvinoita kuti simba guru rinofambiswa, kuderedza kuratidzwa uye kurasikirwa kwechiratidzo.
3. Signal Conditioning: Power amplifiers inogona kuva nesignal conditioning stages kuti iwedzere kunaka kwechiratidzo chekupinza, kubvisa ruzha, kana kushandisa sefa chaiyo kuti igadzirise zvinobuda kune imwe purogiramu.Aya matanho anogona kusanganisira preamplifiers, equalizers, kana mafirita.
4. Dziviriro yedziviriro: Maseketi emagetsi amplifier kazhinji ane akavakirwa-mukati edziviriro yekudzivirira kukuvara kunogona kukonzerwa nemhepo yakawandisa, ikozvino, kana kupisa.Aya maitiro ekudzivirira anobatsira kuwedzera hupenyu hweamplifier uku uchiona kushanda kwakachengeteka.
Mhedziso
Kupfupisa, magetsi amplifier maseketi zvinhu zvakakosha mumhando dzakasiyana dzeodhiyo uye RF zvikumbiro.Maitiro avo, akadai sekubata simba, mutsara, kunyatsoita, uye bandwidth, inotsanangura kugona kwavo kuita.Kunzwisisa mabasa makuru emagetsi amplifiers, kusanganisira kukwidziridzwa kwechiratidzo, impedance matching, chiratidzo chekugadzirisa uye kudzivirira, zvinotibvumira kukoshesa kukosha kwavo mukufambisa vatauri, kutumira masaini uye kupa ruzivo rwepamusoro-soro.Sezvo tekinoroji iri kufambira mberi, magetsi anosimudza magetsi anoenderera mberi nekuchinja kuti ape kuita kwakanyanya, kushanda nesimba, uye kuita kwakasiyana-siyana kune akawanda emagetsi maapplication.
