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 Table 4. performance, which makes it ideal for small portable/mobile The state of the SKY85736-11 is determined by the logic provided applications. The FEM provides up to +31 dB of transmit gain in Table 5. over the frequency band. The LNA supports an enable/disable mode for power savings when not in receive mode and a bypass function for increased receive dynamic range. The PA can be shut off using the PA EN signal (pin 4). The low-loss broadband switch provides the T/R switching function on the SKY85736-11 and has a 1 dB output compression point (OP1dB) of approximately +30 dBm. Skyworks Solutions, Inc.
