The device is fully- in Table 2. The recommended operating conditions are specified matched, and requires few external components for optimal in Table 3 and electrical specifications are provided in Tables 4 performance, which makes it ideal for small portable/mobile through 9. applications. The FEM provides a typical gain of 26 dB. The LNA The state of the SKY85300-21 is determined by the logic provided supports an enable/disable mode and bypass mode for power in Table 10. savings when not in receive mode. The PA can be shut off using the PA EN signal (pin 6). The low-loss SP3T switch provides the T/R switching function on the SKY85300-21. 1 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. 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. Industry-standard ESD handling precautions should be used at all times. Skyworks Solutions, Inc.
