Features
Description
The SKY13588-460LF is a CMOS silicon-on-insulator (SOI),
single-pole, triple-throw (SP3T) switch. The high-linearity
performance and low insertion loss makes the device an ideal
choice for WCDMA handset and data card applications.

Functional Description
The SKY13588-460LF includes an internal negative voltage
generator and decoder that eliminate the need for external DC
blocking capacitors on the RF ports. No external components are
required for proper operation. DC decoupling capacitors can be
added on the VDD and control lines if necessary.
Switching is controlled by two control voltage inputs (V1 and V2).
Depending on the logic voltage level applied to the control pins,
the RFC (RF common) pin is connected to one of three switched
RF outputs (J1, J2, or J3) through a low insertion path, while the
path between the RFC pin and the other RF pins is in a high
isolation state.
to logic low for at least 20 μs. When exiting shutdown mode, the
switch as a 10.5 μs startup time before switching occurs.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13588-460LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The state of the SKY13588-460LF is determined by the logic
provided in Table 4.
Typical performance characteristics of the SKY13588-460LF are
illustrated in Figures 3 through 6.
Shutdown mode is enabled by connecting all control pins to logic
low. This mode reduces the overall current consumption of the
device to 5 μA, typical. To prevent the switch from accidentally
entering shutdown mode during switching, all states must be set

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
Note 2: Any bias voltage applied to the V1, V2, or V3 pins may damage the device if there is no bias voltage also present on the VDD pin. Maximum control voltage cannot exceed VDD.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Evaluation Board Description
Package and Handling Information
The SKY13588-460LF Evaluation Board is used to test the
performance of the SKY13588-460LF SP3T Switch. The board is
made from a two-layer construction with ½ oz. copper cladding
on top and bottom. The first layer material is 12-mil Rogers
4003C. The second layer material is 49-mil of FR4 for a total
board thickness of about 62 mils. The impedance of all RF traces
is 50 Ω.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SKY13588-460LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
An Evaluation Board schematic diagram is provided in Figure 7.
An assembly drawing for the Evaluation Board is shown in
Figure 8.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
