Basic components and basic functions of wireless data transmission module [Copy link]

What are the basic components of a wireless data transceiver? Taking a wireless data transceiver as an example, let's introduce its structure. A wireless data transceiver is generally composed of a transmitter, a receiver, a phase-locked loop, a baseband processor and a modem, a CPU, an RS-232 or RS-485 interface, etc. The basic functions of each component are as follows: (1) Transmitter: modulates the baseband signal to the radio frequency and performs power amplification. (2) Receiver: Demodulates and amplifies the received RF signal to restore it to the baseband signal. (3) Phase-locked loop: Provides a highly stable standard RF signal for the transmitter and receiver. (4) Baseband processing and modulation and demodulation: Filters, amplifies, shapes, modulates and demodulates the baseband signal. (5) CPU: Completes control operation, parameter setting, data processing, interface control and other functions. (6) RS-232/RS-485 Interface: Completes data exchange with user terminal equipment.
