The HSB133 is a module designed for the 433.92 MHz frequency band. Unlike cheaper super-regenerative receivers, the HSB133 uses a local oscillator and mixer stage (superheterodyne architecture) to convert the incoming 433 MHz signal down to a fixed intermediate frequency (IF), typically 1 MHz or 2.25 MHz.
The mechanical and electronic workflow of the HSB133 receiver can be broken down into four distinct phases: hsb133 receiver work
However, users with longer range requirements or applications with high levels of interference may want to consider alternative solutions. The HSB133 is a module designed for the 433
