SKY65352-11 Pinout – 20-Pin MCM (Top View) Technical Description operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Shut Down and T/R Switch Mode Control The SKY65352-11 provides one RF differential port composed of Pin 8 (SDN) is used to enable the device while pin 20 (T_R) the RF_P and RF_N pin signals (pins 5 and 6, respectively). The enables transmit or receive mode. The following control logic is Smith chart shown in Figure 3 plots the impedance of the RF used to configure the transmit, receive, or shut down mode of the differential port. Typical performance characteristics are shown in SKY65352-11: Figures 4, 5, and 6. SDN T_R Mode Package and Handling Information (Pin 8) (Pin 20) High High Transmit mode Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the High Low Receive mode shipping container label regarding exposure to moisture after the Low Low Shut Down mode container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is Bottom Center Paddle subjected to high temperature during solder assembly. The bottom center paddles must be electrically grounded for The SKY65352-11 is rated to Moisture Sensitivity Level 3 (MSL3) proper RF performance. Customers should place adequate at 260 °C. It can be used for lead or lead-free soldering. For thermal vias under the ground paddles for optimum thermal additional information, refer to Skyworks Application Note, PCB performance. The Evaluation Board layout can be used as a guide Design and SMT Assembly/Rework Guidelines for MCM-L for RF ground and thermal layout. Packages, document number 101752.

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.
