Description
The MASWSS0167 is a GaAs pHEMT MMIC single
pole double throw (SPDT) switch in a lead-free
1.2 x 1.5 mm 6-lead PQFN package. This device is
ideally suited for applications where low control
voltage, low insertion loss, moderate isolation, small
size and low cost are required.
Typical applications are for filter and antenna
switching in wireless LAN systems that connect
separate receive functions to a common antenna, as
well as other handset and general purpose switching
applications.
The MASWSS0167 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.
M/A-COM Technology Solutions Inc. (MACOM) and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.

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 - 500 MHz, 39 pF for 0.5 - 3 GHz.
