The device is fullymatched, and requires few external components for optimal performance, which makes it ideal for small portable/mobile applications. The FEM provides up to +30 dB of gain 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 6). 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.

Evaluation Board Description Circuit Design Considerations The SKY65535-11 Evaluation Board is used to test the performance of the SKY65535-11 FEM. A suggested application schematic diagram is shown in Figure 3. A photograph of the Evaluation Board is shown in Figure 4. The following design considerations are general in nature and must be followed regadless of final use or configuration: 7B Evaluation Board Test Procedures 1. Connect the system ground to connector J4, pin 2, of the Evaluation Board. 2. Apply 3.6 V to connector J4, pins 1 and 3. 3. Apply 3.3 V to connector J5, pin 1. 4. Select a path to test according to the modes shown in Table 7. 5. Connect a multimeter or oscilloscope to connector J5, pin 12, to monitor the power detector voltage. 6. Apply an RF signal to connector J1 (ANT) to monitor the RX to ANT performance. Measure the response from the output of connector J2 (RX). 9B 7. Apply an RF signal to connector J3 (TX) to monitor the ANT to TX performance. Monitor the output power on connector J1 (ANT). Care should be taken not to overdrive the amplifier by applying too much RF on the input to the device (–20 dBm provides a suitable starting input power for the device). 1. Paths to ground should be made as short as possible. 2. The RX and ANT ports are AC-coupled and do not require DC blocking capacitors. The TX port (pin 8) has an on-chip inductor to ground followed by a DC blocking capacitor between the inductor and the die. Therefore, there is no DC present on this port. 3. If the TX port is connected to an external component with DC present on it, a 10 pF (component C8) general purpose blocking capacitor is recommended. 4. Capacitors C6 (1 μF) and C7 (100 pF) should be on the primary side of the Evaluation Board at a minimum manufacturable distance from the FEM. 5. The ground pad of the SKY65535-11 has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required. 6. Trace losses are as shown in Table 8. NOTE: A poor connection between the slug and ground increases junction temperature (TJ), which reduces the lifetime of the device.
