The encoding methods we commonly use in wireless transmitter modules are fixed code and rolling code. The rolling code is an upgraded product of fixed code,if confidentiality is involved, rolling coding is used.Even if there is such a coding method, it has the function of remote control. The following is a small series of remote technology to explain the performance and advantages of the wireless transmitter and receiver module.

Three advantages of wireless transmitter and receiver module.

1. The wireless transmitter and receiver module has very small radiation, and the shielding effect of the mesh grounding copper foil on the back of the circuit module can reduce the leakage of its own oscillation and the invasion of external interference signals.

2. The antenna input terminal has a frequency selection circuit, and does not rely on the frequency selection function of the 1/4 wavelength antenna. When the control distance is close, the external antenna can be cut short or even removed.

3. The waveform of the output end of the wireless transmitter ande receiver module is relatively clean, the interference signal is a short needle pulse, and unlike other super-regeneration receiving circuits, a dense noise waveform is generated, so the anti-interference ability is strong.

Anti-interference performance of the wireless transmitter module: Its main advantage is its strong anti-interference performance. The so-called anti-interference is good, mainly refers to the wireless transmitter module under the same conditions of input signal-to-noise ratio (referred to as signal-to-noise ratio S/N), the signal-to-noise ratio of the output of the FM receiver of the wireless transmitter module is greater than the signal-to-noise ratio of the output of the AM receiver.  The wireless transmitter module adopts the SAW frequency stabilization of the acoustic table resonator, the frequency stability of the wireless transmitter module is extremely high, and the cost is very high. The wireless transmitter module has perfect antistatic protection and has a good effect in the industry.

 

In summary, when selecting a wireless transmitter module, users must pay attention to whether their products are used in more complex environments, or in a simpler environment, and the life cycle of products. If the product is to be stable and consistent, it is necessary to choose a superheterodyne wireless transmitter module. If the user’s product life cycle is short, such as remote control toys, motorcycle alarms and other low-priced products, in order to save costs, you can choose super-regenerative wireless transmitter module.
