A Few Fundarnentalls About Semiconductors
The diode, one of the simplest of
semiconductor devices, functions as a

flowing in one direction and as a
virtually "open" conductor for current
flowing in the opposite direction.
Diodes are most commonly made
by growing materials with p-type
impurities on materials with n-type
impurities to form what is known as
a pn junction.
These devices are said to be for-
ward-biased when conventional cur- . *
rent flows from the anode, or p-type
material, across the junction to the Rectifiers-power diodes used Since the depletion region acts as
cathode, or n-type material, with a primarily for power rectification in a dielectric between two conducting

Therefore, by changing the bias on
the PIN diode from reverse to forward,
usually by high-speed digital signals,
the PIN diode is able to act as a high-
speed switch.
These diodes are rated for use at
different frequency ranges such as
VHF, UHF and SHF (superhigh fre-
quency). VHF PIN diodes are used
for general-purpose switching, but
UHF and SHF PIN diodes are used
in attenuators and modulators as
well as switches.
