1. Transmitting 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.
2. Transmitter module has an external extra reliable power magnifying circuit, which improves tremendously the transmitting power and efficiency, the transmitting distance reaches 2000m-4000m and it makes it possible to control in very far distance.
3. Frequency error is generally within +/-75KHz, not like LC oscillating circui of which the error is around  +/-500KHz, so that guarantee the reliability.
4. As the decoder is a kind of normal encoding circuit made through CMOS technique with low power consumption and low price, under the normal conditions, the quiescent current is almost zero.
5. The transmitter module generally requires DC9V as operating voltage, DC12V will shot the magnifying tube, only could be used less than one second. If the voltage is less than DC9V, the transmitting power will be less and the transmitting distance will be shorter.
6. Factory setting frequency is normally 315Mhz, the frequency can be adjusted from 260MHz to 433MHz in case of special requirement.
7. Code secrecy function, fixed code/hopping code selectable, there are 6561 address codes for fixed code unit and more than 200 million address codes for hopping code unit.
8. Can be used in car anti-theft system, home anti-theft system, remote control toy and other remote control electric appliances etc.
