Description
M/A-COM’s MASW-008853 is a GaAs PHEMT
MMIC single pole double throw (SPDT) high power
switch in a low cost SC70 six lead package. The
MASW-008853 is ideally suited for applications
where high power, low control voltage, low insertion
loss, high isolation, small size and low cost are
required.
Typical applications are for CDMA handset systems
that connect separate transceiver and/or GPS
functions to a common antenna, as well as other
related handset and general purpose applications.
The MASW-008853 can be used in all systems op-
erating up to 3 GHz requiring high power at low
control voltage.
The MASW-008853 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

5. For positive voltage control, external DC blocking capacitors are required on all RF ports.
6. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.

Handling Procedures
Please observe the following precautions to avoid
damage:
7. For positive voltage control, external DC blocking capacitors
are required on all RF ports.
8. Differential voltage, V(state 1) - V(state 0), must be +2.7 V
minimum, but must not exceed 8.5 V.
9. 0 = -5 V to +2.3 V, 1 = -2.3 V to +5 V.
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.
