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 3 mm 12-lead
PQFN package. The MASWSS0060 is uniquely
configured to enable switching from a common an-
tenna port to CDMA cellular, CDMA PCS, or GPS
ports.
The design is symmetric and has been fully opti-
mized for excellent cross modulation performance in
all three paths while still maintaining excellent inser-
tion 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 RF3 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 reliabil-
ity.

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

4. Exceeding any one or combination of these limits may cause
permanent damage to this device.
5. M/A-COM does not recommend sustained operation near
these survivability limits.
6. Differential voltage, V (state 1) -V (state 0) must be 2.6 V
minimum and must not exceed 8.5 V.
7. 0 = -5 V to 2.4 V, 1 = -2.4 V to 5 V.
