Description
Gallium
Arsenide
PIN
diodes
offer
improved
performance characteristics over silicon in many
microwave
semiconductor
applications
These
benefits result from the intrinsic semiconductor
properties of GaAs. Its inherent high carrier mobility
results in a low resistance fast switching device. The
low carrier concentration in the I region layer
produces a near zero punch through bias voltage.
Gallium Arsenide's high band gap also assures it will
operate at high operating temperatures.
Switching speeds in the low nanosecond range
using an inexpensive TTL buffer logic is attainable
with GaAs PIN diodes. This performance can be
achieved because GaAs PIN diodes exhibit high
impedance at a positive bias (up to .5V). Reverse
bias is not required for many GaAs PIN diode
applications. Low loss, in switch and phase shifter
circuits at frequencies up to 40 GHz is possible as a
result of low parasitic series resistance in the
conducting and non-conducting states.
M/A-COM’s GaAs PIN diode chips are also available
in several different package styles. See page 4
