DESCRIPTION
M/A-COM’s MA4AGSW5 is an Aluminum-Gallium-
Arsenide, single pole, five throw (SP5T), PIN diode
switch. The switch features enhanced AlGaAs anodes
which are formed using M/A-COM’s patented hetero-
junction technology. AlGaAs technology produces a
switch with less loss than a device fabricated using
conventional GaAs processes. As much as a 0.3 dB
reduction in insertion loss can be realized at 50 GHz.
This device is fabricated on an OMCVD epitaxial wafer
using a process designed for high device uniformity
and extremely low parasitics. The diodes within the
chip exhibit low series resistance, low capacitance,
and fast switching speed. They are fully passivated
with silicon nitride and have an additional polymer
layer for scratch protection. The protective coating
prevents damage during handling and assembly to the
diode junction and the chip anode air-bridges. Off chip
bias circuitry is required.

The high electron mobility of AlGaAs and the low
capacitance of the PIN diodes used makes this switch
ideal for fast response, high frequency, multi-throw
switch designs where the series capacitance in each
off-arm will load the input. AlGaAs PIN diode switches
are an ideal choice for switching arrays in radar
systems, radiometers, test equipment and other multi-
assembly components.
