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. Functional Description Electrical and Mechanical Specifications The SKY13392-359LF is comprised of a CMOS decoder that The absolute maximum ratings of the SKY13392-359LF are enables two TTL-compatible DC lines to control four RF ports. The provided in Table 2. Electrical specifications are provided in decoder is internally connected to a GaAs pHEMT RF switch. Table 3. Depending on the logic voltage level applied to the control pins, The state of the SKY13392-359LF is determined by the logic the RFC pin is connected to one of four switched RF outputs (RF1, provided in Table 4. RF2, RF3, or RF4) by a low insertion loss path, while maintaining Typical performance characteristics of the SKY13392-359LF are a high isolation path to the alternate port. illustrated in Figures 3 through 9. The CMOS decoder should have VDD applied before a logic high is applied to one of the control lines. The recommended startup sequence is: Step 1: Apply VDD. Step 2: Apply VC1 and VC2 Step 3: Apply RF input. The device must be turned off in the reverse order. Skyworks Solutions, Inc.
