SKY13522-644LF Block Diagram Description The SKY13522-644LF is a single-pole, double-throw (SPDT) switch used for single-ended switching in cellular applications. Using advanced switching technologies, the SKY13522-644LF maintains low insertion loss and high isolation for all switching paths. Depending on the logic voltage level applied to the control pin (V1), the antenna port (RFC) is connected to one of two switched RF outputs (RF1 or RF2) through a low insertion loss path, while the path between the antenna port and the other RF port is in a high isolation state. The SKY13522-644LF is provided in a small 8-pin, 1.1 x 1.1 mm 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. S3479 Figure 2.

External DC blocking capacitors are required on the RF1 and RF2 ports for proper operation. DC decoupling capacitors may be added on the VDD and control lines if necessary. The absolute maximum ratings of the SKY13522-644LF are provided in Table 2. Electrical specifications are provided in Table 3. Switching is controlled by single control voltage input (V1). Depending on the logic voltage level applied to the control pin, the antenna pin is connected to one of two switched RF outputs. Typical performance characteristics are illustrated in Figures 3 through 6. The state of the SKY13522-644LF is determined by the logic provided in Table 4. 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. 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.
