Features of RF Module: 1.Receiverfrequency 433MHz.Instagram:https://instagram. ccrm denver 3.4.1 Radio as a Cascade of Two-Ports. The front end of an RF communication receiver or transmitter combines a number of subsystems in cascade. The design of the RF front end requires trade-offs of noise generated by the circuit, of frequency selectivity, and of power efficiency, which translates into battery life for a communication handset. As the bandwidth B increases, the sensitivity number increases and therefore the receiver becomes less sensitive. (E.g. when the receiver sensitivity goes from -90 dBm to -60 dBm, it has become less sensitive). A ten fold increase in bandwidth – for example from 10 kHz to 100 kHz – reduces the sensitivity by 10 dB. 348 pace bus Radio frequency interference, also known as RFI, is a problem for most consumer electronic devices.
