Microwave is a "line of sight" system, so the two points must be able to "see" each other. If they're linked by satilite, that can be around the world, and if by microwave towers then as far as you can see the tower.

Which vacuum based device is widely used as a power amplifier in satellite communication system?

The Traveling Wave Tube Amplifier (TWTA) is widely used as a power amplifier in satellite communication systems. It amplifies signals in the microwave frequency range and is capable of providing high power output with low noise and distortion. TWTA technology has been utilized for several decades in satellite communication due to its reliable performance and efficiency.


Applications of tunnel diode?

Applications: They are used in low power amplifiers DLVA, microwave and RF power monitors, high-frequency triggers, ALC loops, zero bias detectors, ACP tunnel diode circuits, etc. Since they are more resistant to nuclear radiation, tunnel diodes are used in space applications like amplifiers for satellite communications.


Why high frequency is used in communication than low frequency?

High frequency is used because of the the size of antennas used to transmit and receive the communications signal. The higher the frequency the smaller the antenna.


What is the frequency range used in wireless communication?

2.4GHz is used & OFDM


What is the difference between microwave and an AM signal?

The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.

What is the down link frequency to earth?

The downlink frequency for communication with satellites to Earth can vary depending on the specific satellite and its communication system. Frequencies typically used for satellite downlink to Earth are in the range of UHF (Ultra High Frequency) to Ka-band. The exact frequency used will depend on factors such as satellite design, mission requirements, and regulations.


What is microwave and satellite communication?

AnswerThe term microwave is associated to electromagnetic waves of frequency of the order of MHz .Since the energy carried by the wave is directly proportional to their frequency they are of great use in distance communication. For a simple microwave communication system, a radiator ,a reflector and one receiver antenna are essential. As the wave penetrates through the atmosphere a satellite reflector is usually used. Satellites use Microwaves to send signals.


What is the use of microwave radiation?

Microwave radiation is used for heating food quickly in microwave ovens, in communication technology like satellite transmissions and radar systems, and in medical applications like MRI scans and cancer treatments.


What is microwave satellite communication?

It is communication with a satellite orbiting the planet using microwaves, a type of electromagnetic wave of lower frequency than light but higher frequency than radio waves. Microwaves are often used in this way as they can penetrate the earth's atmosphere, but can travel a long enough distance to reach the satellites, unlike x ray waves.


How are microwave photons utilized in modern communication systems?

Microwave photons are used in modern communication systems to transmit information wirelessly. They are used in technologies such as satellite communication, radar systems, and wireless networks. Microwave photons carry data through the air, allowing for fast and efficient communication over long distances.

In what products do microwave tubes find application?

Microwave tubes were primarily used in high and ultrahigh frequency applications such as radars, telecommunications equipment, military communication and control systems


What is up converter in satellite communication?

Every information sent and received through satellite communication has to have an address to enable the communication process of signal delivery and reception. This naming of the signal is made in the form of a specific frequency. For example each TV channel operates on a unique frequency of it's own. When that frequency is called (tuned technically) out of a spectrum in that band, the chosen frequency gets selected. Since satellite transponders operate at very high frequency, modulation of the signal on to the carrier is difficult. Hence modulation is carried out at a much lower frequency. Such modulated signal is raised to the required frequency( name or address as stated above) that supports the satellite band and the transponder. The equipment used to elevate the frequency of the low frequency carrier (known as Intermediate Frequency) to the satellite transponder frequency is UP CONVERTER C.K.Vasudeva Bangalore


How does a gamma wave differ from a microwave?

Gamma waves are electromagnetic waves with a shorter wavelength and higher frequency than microwaves. They are commonly used in medical imaging and cancer treatment. Microwaves, on the other hand, have longer wavelengths and lower frequencies, and are typically used in household appliances like microwave ovens and satellite communication.
