What are the advantages of superheterodyne receiver module

Wireless modules are widely used in remote control telemetry, access control systems, robot control, industrial data acquisition systems, etc., and are closely related to our daily lives. However, some people don’t understand the module. Sometimes they don’t know whether to choose a super regenerative receiver module or a superheterodyne receiver module. This article will introduce the advantages and disadvantages of the regenerative receiver module and the superheterodyne receiver module, and use these advantages and disadvantages to combine themselves make a choice based on the actual situation.

Advantages and disadvantages of super regenerative receiver module

Advantages: low price, economical

Disadvantages: the frequency is greatly affected by the temperature drift, and the anti-interference ability is poor.

Advantages and disadvantages of superheterodyne receiver module

Advantages: stable frequency, good anti-interference ability, relatively stable performance when combined with single-chip microcomputer, suitable for all-weather work in relatively harsh environments.

Disadvantages: The sensitivity is lower than that of the super regenerative module, and the price is much higher than that of the super regenerative module. The strong signal at close range is blocked.

The above are the advantages and disadvantages of the super regenerative module and the superheterodyne receiver module. Customers in need can choose a suitable wireless module according to their actual situation.
