Antennas are structures or devices used to collect or radiate electromagnetic waves.

RF transmitters are electronic devices consisting of an oscillator, modulator, and other circuits that produce an RF signal

RF amplifiers are devices that accept a varying input signal and produce an output signal that varies in the same way, but with larger amplitude

RF modules are partially finished circuits that can be incorporated into larger designs

RF filters and microwave filters are devices that pass or reject signals by frequency.

RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal

RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications.
