SKY13412-487LF Block Diagram Description The SKY13412-487LF is a single pole, twelve throw (SP12T) antenna switch with integrated GSM transmit harmonic filter. The SKY13412-487LF 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 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 GPIO 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 SKY13412-487LF is manufactured in a compact, 3.0 x 3.8 x 0.75 mm, 30-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 Table 1.

The absolute maximum ratings of the SKY13412-487LF are provided in Table 2. Electrical specifications are provided in Tables 3 through 8. Table 9 provides the control logic for the SKY13412-487LF. The resulting 3rd Order Intermodulation Distortion (IMD3), fRX, is measured over all phases of fFUND. The SKY13412-487LF exhibits exceptional performance for all TRXx ports. 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 Table 2.

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. Note 2: All TRXx ports absolute maximum power are evaluated with GSM modulated signal at 50 Ω matching condition. 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.
