Learn a little about the functions inside the wireless transceiver module [Copy link]

Wireless transceiver module refers to a wireless module used for wireless transmission and reception of data. Wireless transceiver modules are often used in daily life, but what functions do the common transmitting and receiving modules in daily life generally have? The volume of the common wireless transceiver module in daily life is generally 32x17x85 mm, with a 23 cm long metal rod antenna, powered by batteries, with an active battery compartment cover on the back, which can easily replace the battery. The surface resonant frequency stabilization technology is used inside the transmitting and receiving module, and the reliability can be said to be as high as the industrial level. The effective distance measured in the open field can reach 1000m. It is currently a remote control product with better performance and longer distance. At the same time, the internal frequency stabilization of the transmitting and receiving wireless module also adopts imported acoustic surface resonator, which has very good frequency consistency and high stability. The peak transmission power is 0.25W, the working frequency is 433MHZ, and the frequency stability is better than 10-5. There is no need to adjust the frequency point during use, which is particularly suitable for use in radio remote control systems such as multiple transmitters and receivers. It is understood that some wireless module remote controls on the market generally use LC oscillators, which have poor stability and consistency. Even if high-quality fine-tuning capacitors are used, temperature changes and vibrations can hardly ensure that the frequency point that has been adjusted will not shift, thereby shortening the transmission distance. With the continuous improvement of social living standards, people's requirements for materials are getting higher and higher. The performance requirements of wireless transceiver modules are the same. This also means that enterprises need to continuously innovate technology and upgrade product performance in order to better serve the people and promote the continuous development and progress of enterprises.
