Description
The MASW-008543 GaAs monolithic switch
provides high isolation in a lead-free, plastic surface
mount package. This device is ideal for applications
across a broad range of frequencies.
MACOM fabricates the MASW-008543 using a
0.5-micron gate length pHEMT process. The
process features full chip passivation for
performance and reliability.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.

7. VLOW = 0 V ± 0.2 V, VHIGH = 1.8 V to +5 V, minimum VHIgh -
VLOw = 1.8 V, maximum VHIgh - VLOw = 8.0 V.
8. For use at low voltage, MACOM recommends connecting a
20K pull up resistor on pin 3 to a voltage equal to the most
positive control voltage.
9. Negative control voltage may be used. The VHIGH in the table
would be the most positive (0 V) and the VLOw would be the
most negative (-3 V for example).

Insertion Loss Isolation
Applications Section—Low Frequency Measurement
Return Loss This data shows the MASW-008543 measured on
an evaluation board with 0 Ω resistors. The board
and connector loss have been removed.
0 Ω resistors can be used if negative control is
available. To avoid changing the device bias
points, the device should not be exposed to DC
potentials on the RF ports.
With positive control MACOM recommends using
DC-Blocking capacitors large enough that their
Xc is insignificant at the frequency of use. At
50 MHz a capacitor value greater than 1000 pF is
recommended.
