Extending The Range of 433 MHz with HC-12 / HC-11 & MAX263AXT LNA Radio Signal Booster / Amplifier

This guide we will going extend / amplify the 433 MHz radio signal with MAX263AXT. However, HC-12 alone already reach to 2KM (2000 meter in open range ) so perhaps we can extend it more with the help of MAX263AXT LNA. The MAX2634 LNA (Low-Noise Amplifier) combined with low-power shutdown mode enhanced ...
