Why RC oscillators are not suitable for high frequency generation?

Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.

Why crystal oscillator used for microcontrollers?
Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.
Why RC oscillators are not used for high frequencies?
The "C" in RC is capacitance, and at high frequencies, the C will shunt the signal more than at lower frequencies. The loss through the cap will climb right along with frequency. And as the cap's performance goes down, so, too, does the circuit performance. RC oscillator performance is far from linear at the top of the frequency range.
What are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
What are 3 forms of Electromagnetic Radiation with a wavelength less than visible light?
The wavelength of electromagnetic radiation is a measure of the frequency; multiply the frequency times the wavelength, and the answer is ALWAYS the "Speed of Light", which we abbreviate as "c". All of these are different "bands" of electromagnetic energy. Radio is the longest wavelength and lowest frequency. "Low Frequency" is the lowest, followed by "high frequency", "very high frequency" or VHF, "ultra-high frequency" or UHF. Beyond that are microwaves, and then heat, then "infrared", and then visible light. Higher frequency (and shorter wavelengths) than light are "ultra-violet", then X-rays, and then "gamma rays".
Which filter is used for passing only high frequency?
ladder

What type of products does Vectron International produce?
Vectron International produces frequency generation and control products. Some examples of products made are timing modules, high tech electronics, clocks/crystal oscillators, and sensor products just to name a few.
What are the advantages and disadvantages of oscillators?
The biggest disadvantages with oscillators are that they have to be stabilized with control heaters. If the oscillator is operated in a non temperature controlled environment it will drift off frequency and it is not good policy to transmit over a wider that necessary bandwidth. The frequency on either side of the offending transmitter will be affected.
Why 1St generation computer not suitable for high calculation?
but they were. for the time they were built they were and did.

What is the difference between a high frequency UPS and a Low frequency UPS?
The difference is in sine wave generation algorithm. In HI freq - it is 30kHz signal, modulated by 50Hz.

What does the U stand for in UHF?
Ultra high frequency.
What frequency does high energy electromagnetic have?
High energy is high frequency.
What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
