Laaj 1: Lan mooy poñ yiñ jagleel Resonator SMD SAW bu Suzhou Hangjing 2.0 x 1.6-SR21S4 Serie?
A: Puntu fréquence yiñ miin ñooy 303, 315, 390, 433.92, 435, 72, fekk mën nanu leen méngale ak parametru kiliyaan yi.
Q2: Jafe-jafe yi gëna bari ak saafara yi ci Resonator Onde Akustik (SAW) ci kaw suuf?
A: Deviation frequency
1) Màndarga: Fréquence biy génn ci sircuit bi méngoowul ak fréquence nominal bi ci resonator SAW bi, te deviation bi dafa weesu li ñuy may.
2) Sabab: Kapasite sargal mënul méngoo: Resonator SAW yi dañu sensible lool ci sargal kapasite (CL). Liy gëna faral di indi coppite ci fréquence mooy ñàkka méngoo gi am ci digganté capacité charge bi ci circuit bi ak valeur bi resonator bi soxla.
3) Solution: Njàngale capacitance sargal njub: Jëfandikool ndànk ndànk ndànk (daanaka ñaari kondansatër bitti) ci sircuit oscillator ni ñu ko leeralee ci fiche de données. Tuning bu baax ci condensateur yii mën na "dindi" fréquence bi.
