DESCRIPTION
M/A-COM’s MA4AGSW1 is an Aluminum-Gallium-
Arsenide, single pole, single throw (SPST), PIN
diode switch. The switch features enhanced AlGaAs
anodes which are formed using M/A-COM’s pat-
ented hetero-junction technology. This technology
produces a switch with less loss than conventional
GaAs
processes. As much as a 0.3 dB reduc-
tion in insertion loss can be realized at 50GHz.
These devices are fabricated on an OMCVD epi-
taxial wafer using a process designed for high de-
vice uniformity and
extremely low parasitics. The
diodes themselves
exhibit low series resistance,
low capacitance, and fast switching speed. They are
fully passivated with silicon nitride and have an addi-
tional polymer layer for scratch protection. The pro-
tective coating prevents damage to the diode junc-
tion and anode air-bridges during
handling and
assembly. Off chip bias circuitry is
required.

APPLICATIONS
The high electron mobility of AlGaAs and the low
capacitance of the PIN diodes makes this switch
ideal for fast switching, high frequency, multi-throw
switch designs. These AlGaAs PIN switches are
used in switching arrays for radar systems, radiome-
ters, test equipment and other multi-assembly com-
ponents.
