Description
Anode
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

Ordering Information
The GaAs Chip specifications shown in the table on page 2 are for the stand alone die, package style 277. Note that the
table lists the bare die junction capacitance and that the total capacitance for the base part in an alternative package will
differ. The total capacitance in an alternative package can be computed by adding the capacitance shown in the table
on page 2 to the parasitic capacitance of the alternative package as defined in the
Package Parasitic Capacitance
table below. The base part numbers are only available in the case styles shown in the
Package Availability Table
below. To order, indicate the base part number followed by a dash and the desired package style.
For example:
The MA4GP030-30 is the MA4GP030 chip in the 30 style package.
