Description
M/A-COM’s MASWSS0192 is a GaAs PHEMT
MMIC SPDT switch in a lead-free SC-70 (SOT-363)
surface mount plastic package. The MASWSS0192
is ideally suited for applications where very small
size and low cost are required.
The MASWSS0192 can be used for low / medium
power, low loss requirements in all systems
operating up to 3 GHz, including PCS, GSM, DCS,
Blue Tooth, T&M, and other receive chain applica-
tions.
The MASWSS0192 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

4. Alternate voltage operation of VC = 0 V / 5 V or -5 V / 0 V will yield similar insertion loss, isolation, VSWR, switching, RON, and gate lag results.
5. For positive voltage control, external DC blocking capacitors are required on all RF ports.
6. 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 - 3 GHz.
Qualification
Qualified to M/A-COM specification REL-201,
Process Flow –2.
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.

7. Differential voltage, V (state 1) - V (state 0), must be 2.5 V
minimum, but must not exceed 8.5 V.
8. 0 = 0 V to 0.5 V; 1 = 2.5 V to 5 V or
0 = -5 V to -2.5 V, 1 = -0.5 to 0 V.
