Description
The SKY13335-381LF is a pHEMT GaAs FET I/C switch. The
device features low insertion loss and positive voltage operation
with very low DC power consumption. The switch is manufactured
in a compact, low-cost 1.5 x 2.0 mm, 6-pin Micro Leadframe
Package Dual (MLPD) package.
The switch may be used in transmit/receive applications by
connecting the RF common port (RFC, pin 5) to either the OUT1 or
OUT2 port (pins 1 or 3, respectively) using a low-loss path (i.e., a
positive voltage applied to either the VCTL1 or VCTL2 pins). The
switch is a reflective short on the isolated port.
The 6-pin MLPD package and pinout are shown in Figure 1. A
functional block diagram is shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1. The absolute maximum ratings of the SKY13335-381LF
are provided in Table 2 and recommended operating conditions
listed in Table 3. Electrical specifications are provided in Table 4.
Typical performance characteristics for the SKY13335-381LF are
shown in Figures 3, 4, and 5.
The state of the SKY13335-381LF is determined by the logic
provided in Table 5.

Evaluation Board Description
The SKY13335-381LF Evaluation Board is used to test the
performance of the SKY13335-381LF 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 Dimensions
The PCB layout footprint for the SKY13335-381LF 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
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. 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 SKY13335-381LF 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.
