Converts the incoming signal to an Intermediate Frequency (IF) signal and performs: Carrier frequency tuning – selects desired signal. Filtering – separates signal from other modulated signals picked up. Amplification – compensates for transmission losses in the signal path.
What Is RF and Why Do We Use It? | Introduction to RF Principles …
“RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection. Time-varying voltages and currents generate electromagnetic energy that propagates in the form of waves.
Radio-frequency engineering - Wikipedia
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz. [1][2][3] It is ...
Radio frequency - Wikipedia
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.
