Description
The SKY13526-485LF is a single-pole, six-throw (SP6T) antenna
switch with a Mobile Industry Processor Interface (MIPI).
Using advanced switching technologies, the SKY13526-485LF
maintains low insertion loss and high isolation for both transmit
and receive switching paths. The high linearity performance and
low insertion loss achieved by the SKY13526-485LF makes it an
ideal choice for UMTS, CDMA2000, EDGE, and LTE applications.

Figure 1. SKY13526-485LF Block Diagram
Depending on the logic applied to the decoder, the antenna pin is
connected to one of six switched RF ports using a low insertion
loss path, while the paths between the antenna pin and the other
RF pins are in a high isolation state. Switching is controlled by the
MIPI decoder. There is an external MIPI select pin that enables
how the switch responds to power mode triggers. When this pin is
grounded, the switch responds to any of the power mode triggers.
When this pin is left open, the switch responds to individual
power mode triggers. No external DC blocking capacitors are
required on the RF paths as long as no DC voltage is applied.
The SKY13526-485LF is manufactured in a compact,
2 x 2 mm, 14-pin surface mount Quad Flat No-Lead (QFN)
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

The resulting 3rd Order Intermodulation Distortion (IMD3), fRX, is
measured over all phases of fFUND. The SKY13526-485LF exhibits
exceptional performance for all TRXx ports.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13526-485LF are
provided in Table 2. Electrical specifications are provided in
Tables 3 through 7.
IMD2 and IMD3 test conditions for various frequencies are listed
in Tables 8 and 9, respectively.
Triple Beat Ratio (TBR) test conditions for bands 2 and 5 are listed
in Table 10.
Figure 3 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 TRX6 ports, while a –15 dBm CW
blocker signal, fBLK, is applied to the ANT port.
Table 11 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 4 and 5 provide the timing diagrams for register write
commands and read commands, respectively.
Table 12 provides the Register_0 logic. Table 13 describes the
register parameters and bit values.

Note 1: 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.

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 SKY13526-485LF Evaluation Board is used to test the
performance of the SKY13526-485LF SP6T Switch. An Evaluation
Board schematic diagram is provided in Figure 6. A
recommended ESD protection circuit diagram is provided in
Figure 7. An assembly drawing for the Evaluation Board is shown
in Figure 8.
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 SKY13526-485LF 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 SKY13526-485LF is provided in
Figure 9. The typical part marking is shown in Figure 10. Package
dimensions for the 20-pin QFN are shown in Figure 11, and tape
and reel dimensions are provided in Figure 12.
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.
