Description
M/A-COM's MASWSS0060 is an industry leading GaAs
PHEMT MMIC single pole three throw (SP3T)
CDMA-GPS switch in a low cost FQFP 12-lead 3x3mm
package. The MASWSS0060 is uniquely
configured to enable switching from a common antenna
port to CDMA cellular, CDMA PCS, or GPS ports. The
design is symmetric and has been fully optimized for
excellent cross modulation performance in all three paths
while still maintaining excellent insertion loss and isolation.
Note that since the design is symmetric, the user can assign
CDMA cellular, CDMA PCS and GPS to ports RF1, RF2
or RF 3 at his or her discretion.
The MASWSS0060 is fabricated using a 0.5 micron gate
length GaAs PHEMT process. The process features full
passivation for performance and reliability.

1.
External DC blocking capacitors are required on all RF ports.
2.
Insertion Loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 500 MHz, 100pF for
0.5 GHz - 2.5 GHz.

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