Description
M/A-COM’s MASWSS0176 is a GaAs PHEMT
MMIC single pole, double throw (SPDT) switch in a
low cost, lead-free SOT-26 surface mount plastic
package. The MASWSS0176 is ideally suited for
applications where small size and low cost are
required.
Typical applications are dual band systems which
require switching between small signal components
such as filter banks, single-band LNAs, converters,
etc. This part can be used for low power, low loss
requirements in all systems operating up to 3 GHz,
including PCS, GSM, DCS, Satellite Radio, Blue
Tooth, and other receive chain applications.
The MASWSS0176 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

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 - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.

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.
