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.
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.
Functional Description
Switching is controlled by three control voltage inputs, V1, V2, and
V3 (pins 9, 6, and 1, respectively). Depending on the logic voltage
level applied to the control pins, the RFC pin is connected to one
of the three switched RF outputs (RF1, RF2, or RF3) using a low
insertion loss path, while the paths between the RFC pin and the
other RF pins are in a high isolation state.
DC blocking capacitors are required on all RF ports of the switch.
The value of the capacitors determines the low frequency
operation. The isolated RF output ports are internally teminated to
50
Ω.
The return loss in the isolation state is limited by on-chip
capacitors.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13408-465LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
Typical performance characteristics of the SKY13408-465LF are
illustrated in Figures 3 through 6.

“1” = +2.5 V to +5.0 V. “0” = 0 V to +0.2 V. Any state other than described in this Table places the switch into an undefined state. An undefined state will not damage the device.
Evaluation Board Description
The SKY13408-465LF Evaluation Board is used to test the
performance of the SKY13408-465LF SPDT Switch. An Evaluation
Board schematic diagram is provided in Figure 7. An assembly
drawing for the Evaluation Board is shown in Figure 8.
Package and Handling Information
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 SKY13408-465LF 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.
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.
Package Dimensions
