Description
M/A-COM’s MA4AGSW2 is an Aluminum-Gallium-Arsenide
anode enhanced, SP2T PIN diode switch. AlGaAs anodes, which
utilize M/A-COM’s patent pending hetero-junction technology,
which produce less loss than conventional GaAs processes, as
much as 0.3 dB reduction in insertion loss at 50 GHz. These
devices are fabricated on a OMCVD epitaxial wafer using a
process designed for high device uniformity and extremely low
parasitics. The diodes themselves exhibit low series resistance,
low capacitance, and fast switching speed.
passivated with silicon nitride and have an additional layer of a
polymer for scratch protection. The protective coating prevents
damage to the junction and the anode airbridges during handling.
Off-chip bias circuitry is required and allows maximum design
flexibility.
Applications
The low capacitance of the PIN diodes used makes it ideal for use
in microwave multi-throw switch designs, where the series
capacitance in each off-arm will load the input. Also, the low
series resistance of the diodes helps the total insertion loss of the
devices at microwave frequencies. These AlGaAs PIN switches
are used as the switching arrays for radar systems, radiometers, and
other multi-assembly components.
