Description
The SKY13270-92LF is a PHEMT GaAs FET IC high-linearity SPDT
switch. This wideband switch has been designed for use from
100 MHz to 2.5 GHz, where extremely high linearity, low control
voltage, high isolation, low insertion loss, and ultraminiature
package size are required. It can be controlled with positive,
negative, or a combination of both voltages. The RF signal paths
within the SKY13270-92 are fully bilateral.
Some standard implementations include T/R switching and
diversity switching over 3 W. The SKY13270-92LF switch can be
used in many analog and digital wireless communication systems
including cellular, GSM and UMTS applications.
Switching is controlled via two control voltage inputs. Depending
upon the voltage level applied to the control voltage pins, the
common RF port (J
1
) is connected to one of two RF ports (J
2
or
J
3
) via a low insertion loss path, while the path between J
1
and
the other RF port is in its isolation state. When the control volt-
ages are toggled, the states between J
1
and J
2
, as well as J
1
and
J
3
, are also toggled.
This part is available in a lead (Pb)-free, 6-lead SC-70 package
which is RoHS-compliant.
An evaluation board is available upon request.

Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
