Description
M/A-COM’s SW -485 is a GaAs PHEMT MMIC SPDT
switch in a low cost SC-70 (SOT-363) surface mount plas-
tic package. The SW-485 is ideally suited for applications
where very small size and low cost are required. Typical
applications are dual band systems where switching b e-
tween small signal components is required such as filter
banks, single-band LNAs, converters, etc. This part can be
used for low power, low loss requirements in the all sys-
tems operating up to 3 GHz, including PCS, GSM, DCS,
Blue Tooth, and other Rx chain applications.

Static Sensitivity
Gallium Arsenide Integrated Circuits are ESD sensitive and
can be damaged by static electricity. Proper ESD tech-
niques should be used when handling these devices.

3. Insertion Loss can be optimized by varying the DC Blocking Capacitor value, i.e. 1000 pF for 100 MHz—1GHz, 39 pF for
0.5 GHz—3 GHz.
