Description
M/A-COM’s MASWSS0065 is an industry leading
GaAs PHEMT MMIC single pole three throw (SP3T)
CDMA-GPS switch in a 3 mm 12-lead PQFN pack-
age.
The MASWSS0065 is uniquely configured to enable
switching from a common antenna port to CDMA
cellular, CDMA PCS, or GPS ports. The design is
asymmetric and has been fully optimized for excel-
lent cross modulation performance in CELL and
PCS paths while still maintaining excellent insertion
loss and isolation.
The MASWSS0065 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and reliabil-
ity.

3. For positive voltage control, external DC blocking capacitors are required on all RF ports.
4. 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.

5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. M/A-COM does not recommend sustained operation near
these survivability limits.
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 +2.6 V
minimum, but must not exceed +8.5 V.
9. 0 = -5 V to +2.4 V, 1 = -2.4 V to +5 V.
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.
