isolation state. No external DC blocking capacitors are required on
the RF paths.
Features
 Broadband frequency range: 0.4 to 2.7 GHz
 Low insertion loss
 High isolation and linearity
 Integrated, programmable MIPI interface

Note:
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.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13473-12-569LF are
provided in Table 2. Electrical specifications are provided in
Tables 3 through 6. Figure 3 provides the timing diagram for turnon time and switching time.
IMD2 and IMD3 test conditions for various frequencies are listed
in Tables 7 and 8, respectively.
Triple Beat Ratio (TBR) test conditions for bands 2 and 5 are listed
in Table 9.
Figure 4 illustrates the test setup used to measure
intermodulation products. This industry standardized test is used
to simulate the WCDMA Band 1 linearity of the antenna switch. A
+20 dBm Continuous Wave (CW) signal, fFUND, is sequentially
applied to the TRX1 through TRX10 ports, while a –15 dBm CW
blocker signal, fBLK, is applied to the ANT port.
The resulting 3rd Order Intermodulation Distortion (IMD3), fRX, is
measured over all phases of fFUND. The SKY13473-12-569LF
exhibits exceptional performance for all TRXx ports.
Table 10 describes the register content and programming
read/write sequences. Refer to the MIPI Alliance Specification for
RF Front-End Control Interface (RFFE), v1.10 (26 July 2011) for
additional information on MIPI programming sequences and MIPI
bus specifications.
Figures 5 and 6 provide the timing diagrams for register write
commands and read commands, respectively.
Table 11 provides the Register_0 logic. Table 12 describes the
register parameters and bit values.

Note 1: Unlike the complete independence between triggers 0, 1, and 2, and also between the associated trigger masks 0, 1, and 2, respectively, as described in the MIPI RFFE Specification,
this device uses additional interactions between the provided trigger functions.
The delayed application of updated data to all triggerable registers in this device may be accomplished using any of the three triggers (0, 1, or 2), provided that the particular trigger
used is not currently masked off. If multiple triggers are enabled, any or all of those are sufficient to cause the data to be transferred from shadow registers to destination registers for
all triggerable registers in the device.
It is also necessary to disable all three triggers (i.e., set all three trigger masks) to ensure that data written to any triggerable register will immediately be written to the destination
register at the conclusion of the RFFE command sequence where the data is written.

Evaluation Board Description
Package and Handling Information
The SKY13473-12-569LF Evaluation Board is used to test the
performance of the SKY13473-12-569LF SP10T Switch. An
Evaluation Board schematic diagram is provided in Figure 7. A
recommended ESD protection circuit diagram is provided in
Figure 8. An assembly drawing for the Evaluation Board is shown
in Figure 9.
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 SKY13473-12-569LF 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,
PCB Design and SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
Package Dimensions
The PCB layout footprint for the SKY13473-12-569LF is provided
in Figure 10. Typical case markings are shown in Figure 11.
Package dimensions for the 20-pin QFN are shown in Figure 12,
and tape and reel dimensions are provided in Figure 13.
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.
