Description
The SKY13290-313LF is a PHEMT IC high-power SPDT switch.
This high-power switch has been designed for use from
500 MHz–2.5 GHz, where low loss, high isolation, low control
voltage 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 SKY13290-313LF
are fully bilateral.
Some standard implementations include T/R switching for
telematic applications at elevated power levels.
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
voltages are toggled, the states between J
1
and J
2
, as well as
J
1
and J3, are also toggled.
The SKY13290-313LF is available in a lead (Pb)-free,
RoHS-compliant, QFN-6 2 x 3 mm plastic package.
An evaluation board is available upon request.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

CAUTION:
Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.

Evaluation Board
The evaluation board for the SKY13290-313 allows the switch to
be fully exercised. The RF common port is marked “J
1
”, and the
two switched RF ports are marked “J
2
” and “J
3
”. All of the RF
ports have SMA connectors mounted. The control voltage inputs
are marked “V
1
” and “V
2
”.
The printed circuit board material is Rogers 4003. The RF
dielectric layer is 0.012 inches thick, ½ oz. copper. The RF
transmission lines are each 50
Ω
(nominal) microstrip.
There are three DC blocking capacitors on the board, C
1
, C
2
and
C
3
, each of which is in series with one of the RF ports. These
capacitors are 47 pF. For improved insertion loss at signal fre-
quencies below approximately 500 MHz these capacitors should
be replaced with larger capacitance capacitors, such as 1000 pF.
