The BARITT diode or Barrier Injection Transit Time diode, bears many similarities to the more widely used IMPATT diode. The first IMPATT oscillation was obtained from a simple silicon p-n junction diode biased into a reverse avalanche break down and mounted in a microwave cavity. A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A semiconductor breakdown diode, usually made of silicon, in which avalanche breakdown occurs across the entire pn junction and voltage drop is then essentially constant and independent of current; the two most important types are IMPATT and TRAPATT diodes. This difference results from asymmetry in the two baritt diode and can be controlled during the manufacture stages of baritt diode diode. They have negative resistance and are .

These diodes include negative resistance, which are used as oscillators to produce amplifiers as well as microwaves. This results from the statistical nature of the avalanche process. Diode adalah komponen aktif dua kutub yang pada umumnya bersifat semikonduktor, yang memperbolehkan arus listrik mengalir ke satu arah (kondisi panjar maju) dan menghambat arus dari arah sebaliknya (kondisi panjar mundur). However it also generates high levels of phase noise as a result of its operation and this means that it is used in simple transmitters more frequently than as a local oscillator in receivers where the phase noise performance is generally more important. Like the more familiar IMPATT diode, the BARITT is used in microwave signal generation, often in applications including burglar alarms and the like, where it can easily produce a simple microwave signal with a relatively low noise level. This brings diode into negative resistance region where generating of very high frequencies can happen. The negative resistance in a BARITT diode is obtained on account of the drift of the injected holes to the collector end of the diode, made of p-type material. Latest arduino projects 1.
