Webb11 apr. 2024 · RF modules are partially finished circuits that can be incorporated into larger designs. They include receivers, transmitters, and transceivers. RF modules use several different modulation methods and radio techniques. On-off key (OOK) modulation turns a signal on or off. Amplitude modulation (AM) causes the baseband signal to vary the ... WebbSummary. Many RF systems incorporate an intermediate frequency (IF) that is lower than the carrier frequency and higher than the baseband frequency. An IF-based receiver is known as a heterodyne receiver. The use of an IF simplifies the design of tunable receivers and reduces the number of components that must be compatible with high frequencies.
