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 capacitors.

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.
