DESCRIPTION
M/A-COM’s MA4AGSW8-1 is an Aluminum-Gallium-
Arsenide, single pole, eight throw (SP8T), 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.
APPLICATIONS
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. AlGaAs PIN diode switches are an
ideal choice for switching arrays in radar systems,
radiometers, test equipment and other multi-assembly
components.

Operation of the MA4AGSW8-1 Switch
The application of either a +15 mA or -15 mA DC bias current to the selected output port will provide the low
insertion loss state. Typically this low loss, “ON” bias voltage through (3) series diodes is 4.5 Volts maximum. All
isolated ports are set to 0V at 0 mA, or, to improve switching speed and isolation, a back bias of 5V/0 mA may also
be applied. RF to DC bias networks are required on all RF ports. To switch the individual RF ports on and off, a
simple single +5V, PIN diode supply, with a TTL gate driver can be used to supply current for the low loss state or
0 V back bias for isolation . In this bias scheme, +5V through a current limiting resistor would be applied at the
common port, J1 and each RF port would be connected to a TTL gate. Low loss would occur when the selected
gate voltage, TTL0, at the output port is 5V/+15 mA and isolation would occur when the selected gate
voltage,TTL1, is -5V/0mA. For faster switching speeds,< 20 nS, a ± 5V ,PIN diode TTL driver should be employed
to help remove the diode stored charge with back bias.
