Antennas are structures or devices used to collect or radiate electromagnetic waves.
|
|
Broadcast television and cable television service providers transmit television over satellite, cable networks and over open airwaves.
|
|
Communication services providers include phone companies, satellite companies, and internet service providers (ISP).
|
|
DC power systems provide continuous DC power through multiple outputs. Most DC power systems include a battery backup, temperature compensation, and other features.
|
|
DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters.
|
|
Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine.
|
|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
|
|
Radio modems are radio frequency transceivers for serial data. They connect to serial ports (RS232, RS422, etc.) and transmit to and receive signals from another matching radio modem.
|
|
RF power dividers and RF power combiners are circuits that accept input signals and deliver multiple outputs that are equal in phase and amplitude. There are two basic product categories: passive and active.
|
|
RF receivers are electronic devices that enable a particular radio signal to be separated from all others being received and converted into a format for video, voice, or data.
|
|
RF transceivers are electronic devices that receive and demodulate an RF signal, then modulate and transmit a new signal.
|
|
RF transmitters are electronic devices consisting of an oscillator, modulator, and other circuits that produce an RF signal.
|
|
Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.
|
|
Transfer switches transfer electrical power back and forth between two power systems or buses such as a utility power line and a backup motor-generator power supply.
|
|
Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable. They are connected between a power source (such as an electrical outlet) and the equipment to protect (such as a motor or computer).
|
|
Wireless modems transmit modulated data using electromagnetic waves.
