SKY13455-31 Block Diagram Description The SKY13455-31 is a Single-Pole, Twelve-Throw (SP12T) antenna switch with integrated GSM transmit harmonic filter. The SKY13455-31 maintains a high linearity, high isolation, and low insertion loss performance, which makes it an ideal choice for UMTS, CDMA2000, EDGE, GSM, and LTE applications. The design features two dedicated GSM transmit ports. The remaining ten ports are suitable for WCDMA transmit/receive and GSM receive functions. Three transmit ports (TRX1, TRX2, and TRX4) have been specifically designed to provide optimal LTE Band 13 performance. The switch exhibits an excellent triple beat ratio and 2nd/3rd order modulation distortion performance. Switching is controlled by an integrated MIPI interface. Depending on the logic applied to the decoder, the antenna pin is connected to one of 12 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. No external DC blocking capacitors are required on the RF paths. The SKY13455-31 is manufactured in a compact, 3.2 x 2.5 x 0.8 mm, 22-pin surface mount Multi-Chip Module (MCM) 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.

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 SKY13455-31 are provided in Table 2. Electrical specifications are provided in Tables 3, 4, and 5. Figure 3 shows a timing diagram for the SKY13455-31. IMD2 and IMD3 test conditions for various frequencies are listed in Tables 6 and 7, respectively. 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 SKY13455-31 exhibits exceptional performance for all TRXx ports. Table 8 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 9 provides the Register_0 logic. Table 10 describes the register parameters and bit values.

A write to these bits programs the USID. 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 can 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 is immediately written to the destination register at the conclusion of the RFFE command sequence where the data is written.

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. 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. Package Dimensions The SKY13455-31 is rated to Moisture Sensitivity Level 3 (MSL3) 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. The PCB layout footprint for the SKY13455-31 is provided in Figure 10. Typical case markings are shown in Figure 11. Package dimensions for the 22-pin MCM 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.
