Description
The SKY13323-378LF is a pHEMT GaAs FET I/C switch. The
switch may be used in transmit/receive applications by
connecting the RF common port (INPUT, pin 5) to either the
OUTPUT1 or OUTPUT2 port (pin 1 or 3, respectively) using a low
loss path (i.e., a positive voltage applied to either VCTL1 or VCTL2
pins). The switch is “reflective short” on the isolated port.
The switch is manufactured in a compact, 1 x 1 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.

Note: “1” = +1.8 V to +5 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 SKY13323-378LF Evaluation Board is used to test the
performance of the SKY13323-378LF SPDT Switch. An Evaluation
Board schematic diagram is provided in Figure 8. An assembly
drawing for the Evaluation Board is shown in Figure 9.
Package Dimensions
The PCB layout footprint for the SKY13323-378LF is provided in
Figure 10. Typical case markings are shown in Figure 11.
Package dimensions for the 6-pin MLPD are shown in Figure 12,
and tape and reel dimensions are provided in Figure 13.
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 SKY13323-378LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 qC. It can be used for lead or lead-free soldering.
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. For packaging details, refer to the Skyworks
Application Note, Discrete Devices and IC Switch/Attenuators
Tape and Reel Package Orientation, document number 200083.
