wat's d application of trappat diode
switch is similar to diode action
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.
by using a suitable diagram, explain the one of the operation in microwave energy sources except Guinn Diode.
In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
Advantages of Trapatt:• higher efficiency than impatt• very low power dissipationAdvantages of Impatt:• This microwave diode has high power capability compare to other diodes.• Output is reliable compare to other diodes.

Backward diode
what is the basic operation of LED
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.
A: A zener is a diode that when connected in the reverse mode current direction it will breakdown to a predetermined voltage any further increasing voltage the breakdown will remain practically the same.

The capacitance of a varicap diode varies as the reverse voltage to the diode changes. As you increase the reverse voltage, the capacitance decreases. And vice versa.
by using a suitable diagram, explain the one of the operation in microwave energy sources except Guinn Diode.
Reverse-biased ---from the book of Malvino
A: The principle is that is a semiconductor meaning will conduct one way only. A switching diode however will have the least of capacitance across its junction so when it disconnect is faster
Very often in translations from German to English the term 'free wheeling diode' for 'Freilauf-Diode' is used. Generally the correct translation for this term would be 'recovery diode'. The usage of the term 'free wheeling' only will be correct in mechanical aspects, e.g. the rear wheel of a bicycle or the clutch of the transmission line of a car.
