Description
M/A-COM’s MASW-007921 is a broadband GaAs
pHEMT MMIC SPDT switch available in a lead-free
2 mm 8-lead PDFN package. The MASW-007921 is
ideally suited for applications where very small size
and high linearity are required.
Typical applications include WiMAX, WLAN, Mesh
networks, fixed wireless access, and other higher
power systems. This switch has a very high initial
compression point, ideal for complex modulations
such as OFDM, with large peak average power
levels.
The MASW-007921 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.
11. M/A-COM recommends connecting unused package pins
(N/C) to ground as shown.
