description: This work is devoted to the development of a small-sized transceiver module of a satellite communication system at 433MHz. During the implementation, the features of communication at this frequency were studied, a review of existing and currently available on the market receivers and transmitters at 433MHz was carried out in order to find out whether it is possible to use them to solve the task: creating a communication channel at 433MHz with a given range. After reviewing the available radio modules that do not meet the range conditions due to low power and low noise immunity, the budget of the communication channel was first calculated to determine which output power of the device will be able to provide stable communication at a given frequency with line of sight. Then the selection of components ensuring the fulfillment of the requirements for the communication range (at least 100 km) in line of sight was carried out, a block circuit with a radio module and an amplifying cascade was built and modeled in the Micro-Cap environment, and then a circuit board circuit for this device was built and diluted in the EasyEDA.
