RF High Power BroadBand Power Amplifiers Dual Directional Couplers
Dual Directional Coupler dia fitaovana mikraoba be mpampiasa indrindra ampiasaina amin'ny fandrefesana herinaratra sy famakafakana famantarana ny famantarana elektromagnetika.Ny tena mampiavaka azy dia ny hoe ny angovo eo anelanelan'ny faritra lehibe sy mpanampy dia azo angonina sy anadihadiana tsy misy fanelingelenana ny faritra lehibe.
Ireto misy endri-javatra hafa:
1. Fifindran'ny roa tonta: Ny DDC dia afaka mandray sy mizara famantarana avy amin'ny lalana maro.
2. Fatiantoka ambany ambany: Ny DDC dia afaka manamaivana ny fiantraikany amin'ny famantarana rehefa manasaraka azy, mitazona ny fahaverezan'ny fampidirana ambany.
3. Fitokanana avo: Ny DDC dia afaka manome fitokana-monina avo eo amin'ny fantsona fandefasana roa mba hisorohana ny fifangaroan'ny bandwidth sy ny fanelingelenana famantarana.
4. Broadband: Ny DDC dia afaka miasa amin'ny faritra midadasika, ka mahatonga azy ireo ho mety amin'ny fampiharana isan-karazany.
5. Consistency: Ny DDCs dia afaka mitazona ny endrika sy ny fepetra mahazatra amin'ny tontolo samihafa, ahafahana miasa mahomby amin'ny rafitra maro.
Fampiharana lehibe:
1. Fandrefesana herinaratra: Afaka mandrefy ny fifandanjan-kery sy mifanandrify amin'ny fizaran-tany mikraoba ny mpangalatra bidirectional, izay tena manampy amin'ny fitadiavana ireo teboka misy lesoka sy ny fanaraha-maso ireo tondro fiasan'ny fitaovana.
2. Famakafakana famantarana: Ny couplers bidirectional dia azo ampiasaina handrefesana ny amplitude sy ny fizaran'ny onjam-peo mikraoba, ary koa ny famakafakana famantarana sy ny sivana.
3. Fanodinana matetika: Ny couplers bidirectional dia afaka mamorona faribolana sy sivana miovaova matetika, ary matetika ampiasaina amin'ny sehatra isan-karazany toy ny fitaovana fandrefesana elektronika, fitaovana radar, fitaovam-pifandraisana amin'ny zanabolana, ary rafi-pifandraisana radio.
4. Fifandraisana nomerika: Matetika ampiasaina ho mpitsikilo, mpandefa, ary fitaovana fanaraha-maso ny mpandray amin'ny fifandraisana nomerika.
Qualwavemamatsy fampifandraisana amin'ny 9kHz ka hatramin'ny 40GHz ny broadband sy ny hery avo roa sosona.Ny couplers dia be mpampiasa amin'ny fampiharana maro.
Ny coupler roa toromarika avy amin'ny Qualwave matetika dia mandrakotra ny 9KHz ~ 67GHz, ny hery dia 1w ~ 5000w, ny fatiantoka ambony indrindra dia 5.7dB, ny directivity ambany indrindra dia 7dB, ary ny onja mijoro ambony indrindra dia 1.8.Tongasoa eto amin'ny fanontaniana.
