These diodes are used in a variety of applications from low power radar systems to alarms. A major drawback of using IMPATT diodes is the high level of phase noise they generate. This results from the statistical nature of the avalanche process. Nevertheless these diodes make excellent microwave generators for many applications. A main advantage is their high power capability. They operate at frequencies between about 3 and 100 GHz or more. http://artizle.blogspot.com
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 Power Diode is used when a large current is involved which needs a larger junction to dissipate the heat generated. An advantage of using the Power Diode is it is able to withstand high voltage without being damaged. A disadvantage about the Power Diode is that being a large junction it is unable to stand high frequency applications.
A: Refers two two diodes connected as it say back to back for gates applications.
Diodes are largely used for changing AC into DC. A half wave diode bridge will use two diodes for this purpose. A full wave bridge uses four diodes to accomplish this task.See related links below.
Silicon (Si) diodes are more commonly used than germanium (Ge) diodes. Silicon diodes are preferred for most applications due to their higher temperature tolerance, lower leakage current, and greater availability. They are commonly used in rectifiers, signal processing, and various electronic circuits. Germanium diodes, while having some advantages in specific applications (such as lower forward voltage drop), are less common in modern electronics.
The read type diode are called impatt diode
Charles Thomas Key has written: 'IMPATT diode amplifier'
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.
These are a niche market, and the demand is not particularly high. Designing a Gunn or Impatt oscillator is not a trivial exercise, and the biasing is a pain. These designs are generally built by skilled craftsmen and are not suited to mass production. At 24 GHz or below, a GaAs MESFET or PHEMT is much more practical as an active device.

0a79 ( germanium diode )in glass construction form is used in AM detector circuits.
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.
Applications of Zener diode: a.)It Regulators. b.)It Controlled Comparators. c.)It Limiters. d.)It is Part in Power Supplies.
The varactor diode is used in frequency tuning applications. Its effective capacitance is a function of the reverse bias voltage across it.
Low efficiency
No, a diode laser and an Nd:YAG laser are two different types of lasers. A diode laser uses a diode as the laser medium and is commonly used for various applications such as hair removal and skin treatments. On the other hand, an Nd:YAG laser uses neodymium-doped yttrium aluminum garnet as the laser medium and is often used for medical and cosmetic procedures, as well as in industrial applications.
If the reverse recovery time of the diode is too long for the operating frequency, the diode will never turn off.
