Products/Services for modulator headend
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. The changes in the parameter(s) of the carrier are made in accordance with an information-bearing signal (modulation signal). Search by Specification | Learn More about QPSK Modulators and BPSK Modulators
I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information. I/Q modulators split an incoming data stream into its in-phase (I) and quadrature (Q) components, mix the resulting signals with local oscillators that are 90º apart in phase, and then combine the outputs vectorially in a 0º mixer.

Optical modulators vary the amplitude and phase of a light beam; e.g., from a laser or by sound waves. Learn More about Optical Modulators
Acousto-optic modulators are devices that use sound waves to modify the amplitude, frequency, or phase of light passing through an acousto-optic material. Search by Specification | Learn More about Acousto-optic Modulators
Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself.

Gunn diodes or transfer electron devices (TED) exhibit a negative resistance region. They are used in high-frequency applications, often for building RF oscillators. Impact ionization avalanche transit-time (IMPATT) diodes are designed to operate at very high frequency and power. They are used as elements in RF and microwave devices. Search by Specification | Learn More about GUNN and IMPATT Diodes
Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure. Search by Specification | Learn More about Access Points
