Description
The MASWSS0175 is a GaAs pHEMT MMIC DPDT
diversity switch in a lead-free 3 mm 12-lead PQFN
package. It is designed for low insertion loss and
allows for independent control and selection of each
switch path. It integrates blocking capacitors on all
RF ports and thus eliminates the need for additional
off-chip DC blocking cap acitors.
The MASWSS0175 is ideally suited for applications
where very small size and low cost are required.
Typical applications are for WLAN IEEE 802.11a
systems that employ two antennas for transmit and
receive diversity. This part can be used in all
systems operating between 4.5 GHz and 6.0 GHz
requiring moderate power and diversity switching.
The MASWSS0175 is fabricated using a 0.5 micron
gate length GaAs pHEMT process. The process
features full 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.
Parameter Absolute Maximum
Input Power @ 3 V Control +32 dBm
Input Power @ 5 V Control +36 dBm
Operating Voltage +8.5 volts
Operating Temperature -40°C to +85°C
Storage Temperature -65°C to +150°C
Absolute Maximum Ratings 3,4
3. Exceeding any one or combination of these limits may cause
permanent damage to this device.
4. M/A-COM does not recommend sustained operation near
these survivability limits.
