800m FST3 On Off Transmitter Head ASK 315Mhz 433Mhz TX Head
Working volt: DC 3-12V
Working current: 5-45mA
Transmitting distance: 800m
Working frequency: 315MHz(more than 20 frequencies optional between 260-440MHz )
Transmitter module uses SAW stable frequency, small temperature excursion, even no excursion with hand touching, which can still guarantee the stable performance in the environment of vibration and big temperature change.
The low price allows it to be the complete substitute of LC oscillating circui.
Frequency error is generally within +/-75KHz, not like LC oscillating circui of which the error is around +/-500KHz, so that guarantee the reliability.
Under the normal conditions, quiescent current is very small.
Wide operating voltage range between DC3~12V;
Factory setting frequency is normally 315MHz/433Mhz, the frequency can be adjusted from 260MHz to 433MHz in case of special requirement.
