2. RF module - Wikipedia

   en.wikipedia.org/wiki/RF_module

   An RF receiver module receives the modulated RF signal, and demodulates it. There are two types of RF receiver modules: superheterodyne receivers and superregenerative receivers. Superregenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave.

   Transmitter - Takes the electrical output of a microphone and then modulates a higher-frequency carrier signal and transmits it as radio waves. Receiver - The broadcast message is received by the receiver and decodes the radio sine waves. Antenna - An antenna is required for transmission; it is also required to receive radio waves. The main use ...

7. Radio receiver design - Wikipedia

   en.wikipedia.org/wiki/Radio_receiver_design

   The reflex receiver was a design from the early 20th century which consists of a single-stage TRF receiver but which used the same amplifying tube to also amplify the audio signal after it had been detected. This was in an era where each tube was a major cost (and consumer of electrical power) so that a substantial increase in the number of ...
