The module has a shutdown mode to minimize power consumption. The operating modes are controlled by the two digital pins (CSD and CTX, pins 15 and 16, respectively). The control logic truth table is provided in Table 8. Transmit Path The transmit path contains an amplifier optimized for saturated performance. The output is internally matched for optimum output power and efficiency into a 50 Ω load impedance. The output is passed through a harmonic filter before being fed through the switch. The input provides a good return loss into a 50 source impedance. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY66115-11 are provided in Table 2. Recommended operating conditions are specified in Table 3 and electrical specifications are provided in Tables 4 through 7. Table 8 shows the mode logic truth table. Typical performance characteristics are shown in Figures 3 through 8. 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. 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.

An Evaluation Board schematic diagram is provided in Figure 9. An optional low-pass filter (LPF) can be incorporated on the ANT port to provide additional rejection of PA output harmonic levels and/or limit unwanted signals from entering the receive path. The board layer detail is provided in Figure 10. Metal Layer 1 = RF traces + control lines. Core thickness between top RF layer and ground plane is critical. Metal Layer 2 = Solid ground plane. No traces routing. Metal Layer 3 and 4 = Control lines + VCC traces (no VCC plane). Pour copper on each layer connected to the ground plane. Use VCC traces in a star distribution pattern. Always use 4 layers.
