FM Transmitter

FM transmitter system board yakavhurika sosi

tsananguro

Kuziviswa kwenguva pfupi

Iyi ndiyo nzira yakapfava yeFM transmitter, inokwanisa kufambisa mimhanzi yenhepfenyuro kana izwi kune huwandu hunosvika makumi mashanu emamita, zvichienderana nerudzi rweantenna inoshandiswa. Iyo sisitimu inoshanda isina tuning uye iyo quartz crystal inoshandiswa yakavharwa kusvika pakukwirira kwe50MHz. Iyi sisitimu inobvisa frequency kudonha, zvakajairika maitiro emazuva ano LC-based transmitter masisitimu.

Circuit system uye nheyo yayo yekushanda



Iyo sisitimu yakavakirwa yakatenderedza yakaderera simba redhiyo amplifier LM386, PN2222A transistor, 1SV149 varactor diode, 30MHz quartz crystal uye zvimwe zvinhu zvakaita se potentiometers, diodes, capacitors uye resistors.

Iyo yakavakirwa-mukati yekuchengetera simba redunhu pamuunganidzi wePN2222A ine inductor L1 uye capacitor C5, uye iyo tuning frequency ndeye 3 yakapetwa frequency yequartz crystal, inova 90MHz. Iyo 90MHz inokwidziridzwa uye yobva yabatanidzwa kuburikidza necapacitor C4 kune waya antenna inoshandiswa kufambisa mimhanzi kana odhiyo kuitira kuti FM inogamuchira 30 t0 50 metres kure inogona kutora kutapurirana.
