I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information.

Quadrature phase shift keying (QPSK) modulators and binary phase shift keying (BPSK) modulators are used to change certain characteristics (amplitude, frequency or phase) of a carrier signal in order to transmit information.

Acousto-optic modulators are devices that use sound waves to modify the amplitude, frequency, or phase of light passing through an acousto-optic material

Chipsets are single chips that provide many of the functions of a motherboard.

Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.

Optical modulators vary the amplitude and phase of a light beam; e.

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