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. ESD HANDLING: 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 when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industrystandard ESD handling precautions should be used at all times. Table 3.

A typical part marking is shown in Figure 6. Package dimensions are shown in Figure 7, and tape and reel dimensions are provided in Figure 8. Evaluation Board Setup Procedure 1. Connect the system ground to pin 2 of connector J4. 2. Apply 3.3 V to VDD pin 6 or 12 of connector J4. 3. Refer to the Control Logic Table in Table 7 to set the device in the desired mode of operation. Set CRX, CTX, and LEN to appropriate VIL and VIH voltages, as specified in Table 3. 4. Transmit performance is monitored by applying an RF signal to the connector J1 (TX) and measuring the output power at the antenna port connector J2 (ANT). 5. Monitor performance in either high gain or bypass mode by applying an RF signal to the antenna port connector J2 (ANT) and measuring the output power at the receive port connector J3 (RX). Package and Handling Information 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 SKY85608-11 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, Solder Reflow Information, document number 200164. 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.
