SKY13386-000 Block Diagram Description The SKY13386-000 is a GaAs pHEMT Single-Pole, Triple-Throw (SP3T) switch designed for 2.4 GHz WLAN applications. The SKY13386-000 is manufactured in a compact, 650 x 650 μm, 8-bump Chip Scale Package (CSP). The small footprint provides the industry’s smallest PCB area needed to implement an integrated SP3T switch. 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. Figure 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. Technical Description Electrical and Mechanical Specifications Switching is controlled by three control voltage inputs (VC1, VC2, and VC3). Depending on the logic voltage level applied to the control pins, the RFC pin is connected to one of three switched RF outputs (RF1,RF2, or RF3) using a low insertion loss path, while maintaining a high isolation path to the alternate ports. The absolute maximum ratings of the SKY13386-000 are provided in Table 2. Electrical specifications are provided in Table 3. DC blocking capacitors are required on all four RF ports for proper operation and to determine the lower frequency operation of the switch. Typical performance characteristics for the SKY13386-000 are illustrated in Figures 3 to 7. The state of the SKY13386-000 is determined by the logic provided in Table 4.

An Evaluation Board schematic diagram is provided in Figure 8. An assembly drawing for the Evaluation Board is shown in Figure 9. Since the 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 Package dimensions for the 8-bump CSP are shown in Figure 10. 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 on film frame. Figure 8.
