Description
M/A-COM’s MASWSS0181 is a GaAs PHEMT
MMIC single pole two throw (SPDT) high power
switch in a lead-free SOT-26 package.
The
MASWSS0181 is ideally suited for applications
where high power, low control voltage, low insertion
loss, high isolation, small size and low cost are
required.
Typical applications are for GSM and DCS handset
systems that connect separate transmit and receive
functions to a common antenna, as well as other
related handset and general purpose applications.
This part can be used in all systems operating up to
3 GHz requiring high power at low control voltage.
The MASWSS0181 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

4. For positive voltage control, external DC blocking capacitors are required on all RF ports.
5. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 500 MHz, 100 pF for 0.5 GHz - 3

6. Differential voltage, V(state 1) - V(state 0), must be +2.5 V
minimum and must not exceed +8 V.
7. 0 = -5 V to 2.5 V, 1 = -2.5 V to +5 V
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.
