Where gunn diode is used?
Gunn diodes are used in GUNN oscillator over high frequency application. its work on the transfer electron effect TET and the scientist J.B Gunn observe it so the phenomenon is named by gunn effect. the diode are made from GaAs material.because silicon is not suitable low forbidden energy gap 1.21eV only.
What is the use of crystal detector in electronics?
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
Why Schottky diodes are used in wave shaping circuits?
Schottky diodes are often used for RF radio frequency applications as a mixer or detector diode. Another common application for the Schottky diode is in power applications as a rectifier.
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.
What is the applicatios and propertyes of diode clamping?
A: T he application are many. Basically it is used to limit and unwanted overshoot of voltage A diode will clamp the voltage or limit the voltage to .7 volts higher and no more.. It can clamp an input clamp negative or positive ringing from a collapsing coil or it can be used to clamp to a voltage.
How does the Switching diode used in television tuning?
A: Those diodes are used as a variable capacitance whereby applying a voltage changes the capacitance which effect the frequency of the tuning circuit
What is the difference between electric diode and electronic diode?
Not sure of your context. A diode is a diode. One artificial distinction might be that an electric diode refers to a diode used in a higher power application with more current where an electronic diode might be found on a circuit board as part of an electronic lower power application.

What is the function of varactor diode?
Voltage controlled variable capacitor. Usually used for dynamic tuning of resonant circuits.
Why can't a conventional pn junction be used for high frequency switching applications?
If the reverse recovery time of the diode is too long for the operating frequency, the diode will never turn off.
What is the effect of temperature on frequency of tuning fork?
The effect of temperature on the frequency of a tuning fork is slight, for the length of the tines is little changed. A steel tuning fork would not be used as a precision frequency reference, though quite adequate for audio purposes. As the temperature increases, the lines will lengthen, and the frequency will decrease.
What is diote?
A diode is semiconductor device which is used in a lot of application in electronics equipment.it is negative temp. coefficient device i.e. at lower temp. it is behave like a insulator and high temp. it is work like a good conductor. Basically a diode is used to convert an alternating current into direct current in form of a rectifier. There are many types of diode used in today day to day life depends upon their application. 1 crystal diode 2 photo diode 3zener diode are some of the most useful diode.

What is the disadvantage of gunn diode?
Gunn Diodes are used in high frequency electronics. The advantages are increased efficiency and improved temperature stability while a disadvantage is the Gunn Diode can get burned out.
What are the application of P-N diode?
Such a diode only lets current pass in one direction. It is used in a variety of electronic circuits. One possible application is as a first step to convert AC to DC.
What is the difference between p n junction and zener diode?
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
Zener diode application?
A zener diode are used in small circuits as shunt regulators to control voltage. It may also be used as voltage references and as surge protectors to limit transient spikes in voltage.
