RF Signal Processing
Edit
RF signal processing is the specialised technical field for manipulating electromagnetic signals falling within radio-frequency spectral bands, typically ranging from kilohertz to hundreds of gigahertz [1]. It implements signal operations such as filtering, frequency up-conversion and down-conversion, modulation and demodulation, interference suppression and power conditioning. Processing can be realised by analogue radio-frequency circuits composed of passive components and active semiconductor devices, or completed in the digital domain after high-speed radio-frequency sampling and digitisation [2]. It acts upon high-frequency carrier-modulated signals intended for wireless radiation through antennas or guided transmission along transmission lines and waveguides. Conceptually it differs from general-purpose baseband digital signal processing which operates upon demodulated low-frequency information signals [3].
