Description
M/A-COM’s SW-489 is a GaAs PHEMT MMIC single
pole three throw (SP3T) high power switch in a low
cost 3 mm 12-lead PQFN package. The SW-489 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
handset and related applications. The SW-489 can
be used in all systems operating up to 2.5 GHz
requiring high power at low control voltage.
The SW-489 is fabricated using a 0.5 micron gate
length GaAs PHEMT process. The process features
full passivation for performance and reliability.

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 - 500 MHz, 100 pF for 0.5 - 2.5 GHz.

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
+2.3 V minimum and less than 5.2 V.
8. 0 = 0 ± 0.2 V, 1 = +2.5 to +5 V
