Description
The SKY13381-374LF is a GaAs pHEMT Double-Pole, Double-
Throw (DPDT) switch designed for 2.4 and 6.0 GHz, dual-band
wireless LAN applications. The switch provides high linearity
performance, low insertion loss, and high isolation in both
frequency bands.
Switching is controlled by two voltage inputs (V1 and V2).
Depending on the logic voltage level applied to the control pins,
the ANT1 and ANT2 pins connect to one of two switched RF
outputs (RX or TX) through a low insertion loss path while
maintaining a high isolation path to the alternate port.
The switch is manufactured in a compact, 1.5 x 1.5 mm, 6-pin
exposed pad plastic Micro Leadframe Package Dual (MLPD)
package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

Evaluation Board Description
The SKY13381-374LF Evaluation Board is used to test the
performance of the SKY13381-374LF SPDT Switch. An Evaluation
Board schematic diagram is provided in Figure 7. Table 6 provides
the Bill of Materials (BOM) list for Evaluation Board components.
An assembly drawing for the Evaluation Board is shown in
Figure 8.
Package Dimensions
The PCB layout footprint for the SKY13381-374LF is provided in
Figure 9. Typical case markings are shown in Figure 10. Package
dimensions for the 6-pin MLPD are shown in Figure 11, and tape
and reel dimensions are provided in Figure 12.
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 SKY13381-374LF 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.
