What types of diodes are used in high frequencies?
Two types used at microwave frequencies are gunn and PIN diodes.
What is function of waveguide in microwave devices?
It replaces a coax cable, which won't work at those frequencies.
What is are unlicensed radio frequencies?
Those which you can use for free, for instance a tv remote control uses such frequencies.
What is the use crystal diode in microwave test bench?
to produce freq in the range of ghz tat is microwave freq range
What is the history of germanium diode?
Germanium point contact diodes were first created and used during World War 2 as detectors in microwave RADAR systems, as the vacuum tubes available at that time did not operate at microwave frequencies. Shortly after World War 2 germanium junction diodes were created.
Does microwave transmission use satellites?
Microwave transmission can be achieved via terrestrial or satellite systems
Do satellites normally use microwaves or radio waves?
Microwaves are radio waves.Most satellites communicate in microwave radio frequency bands.
Do wireless keyboards send data to the computer using microwave frequencies?
Whether a wireless computer keyboard uses microwave frequencies for communication with the computer depends on the technology used by the keyboard, and on the definition of microwave frequencies. Wikipedia defines microwave frequencies to be in the 1...30GHz range. Many wireless keyboards operate in the 2.4GHz band, which would make them microwave transmitters (and receivers). Other keyboards use different frequencies, below 1GHz. Those would not be microwave devices, according to this definition. The 802.15.4 standard, for example, lists a 868.0-868.6MHz band (Europe), 902..928MHz (US) and the 2.4GHz (2400...2483.5 MHz) band (worldwide, but subject to regional restrictions).
Why use microwave for satellites?
The microwave has high enough frequency to carry the information and long enough wavelengths to penetrate the atmosphere. They are also easy to produce and easy to detect.
What is the XM frequency range?
The XM Radio satellites use S-band frequencies from 2,332.50 through 2,345.00 MHz.
What is microwave tube?
microwave tubes are sometime called as vaccum eletrpn device... that are used to generate or amplify microwave radio frequencies.
What is the freqs for satellite radio?
The XM Radio satellites use S-band frequencies from 2,332.50 through 2,345.00 MHz, and Sirius Radio uses adjacent frequencies 2,320.00 through 2,332.50 MHz.
What types of diodes are used in high frequencies?
Two types used at microwave frequencies are gunn and PIN diodes.
Is microwave a fuel?
...No, Microwaves are simply radio waves at certain frequencies.
What waves can transmit TV pictures or cooked food?
Microwave can be use to transmit pictures.
Does GPS satellite have the same frequency with AIS?
GPS Satellites use two frequencies 1.57542 GHz and 1.2276 GHz. AIS operates in the Marine VHF band using channels 87B, 161.975 MHz and channel 88B, 162.025 MHz
Can microwave waves get through atmosphere?
Yes, microwave waves can penetrate the Earth's atmosphere, although they can be partially absorbed by water vapor and oxygen molecules in the atmosphere. This is why some microwave frequencies are used for communication and satellite transmissions, as they are less affected by atmospheric conditions compared to other frequencies.
