A single-pole, double-throw (SPDT) switch selects between the receive and transmit paths. The module has a shut-down mode to minimize power consumption. The receive path contains an LNA with bypass switch. The LNA impedance matching networks are internal to the module and have been optimized for a low NF while maintaining good return losses into a 50 Ω source and load impedance. The receive arm of the SPDT switch and the LNA input are connected to module pins to allow an external filter to be inserted into the receive path. Three digital input pins (CTL1, CTL2, and CTL3) are used to select between transmit, receive, receive bypass, or shutdown mode. Operation Mode Control Transmit Path The four SKY65313-21 operating modes are controlled by the three digital pins: CTL1, CTL2, and CTL3 (pins 2, 3, and 4, respectively). The control logic truth table is provided in Table 2. The transmit path contains a power amplifier (PA) optimized for saturated performance. The PA output is internally matched for optimum output power and efficiency into a 50 Ω load impedance. The PA output is passed through an harmonic filter before being fed through the SPDT switch. The PA input provides a good return loss into a 50 Ω source impedance. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY65313-21 are provided in Table 3. Recommended operating conditions are specified in Table 4. Electrical specifications are provided in Tables 5, 6, and 7. Transmit output power is controlled by the VPC pin, which is normally set to 2.25 V DC voltage. The nominal DC input impedance into the VPC pin is 50 kΩ. Typical performance characteristics of the SKY65313-21 are illustrated in Figures 3 through 22. Table 2.

In the shutdown mode, for the lowest leakage current, the high state is not recommended for CTL1 and CTL3.

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.

A typical application schematic diagram is provided in Figure 23. An Evaluation Board schematic diagram is provided in Figure 24. An assembly drawing for the Evaluation Board is shown in Figure 25. Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. 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. Package Dimensions The SKY65313-21 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 C. It can be used for lead or lead-free soldering. For additional information, refer to Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. A typical part marking is shown in Figure 26. The PCB layout footprint for the SKY65313-21 is provided in Figure 27. Package dimensions are shown in Figure 28, and tape and reel dimensions are provided in Figure 29. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format. 220 pF 28 7 8 VCC_RX 17 VDD1 16 VDD2 GND VCC_TX1 RX3 VCC_TX2 VPC GND GND ANT GND 9 10 11 12 GND 6 CTL3 19 RX2 Antenna 6800 pF 20 CTL2 GND 5 TX VCC_TX3 Transmit Output Power Analog Control 4 13 470 pF 4700 pF 0.047 μF 4.0 V Power Supply 23 21 GND 3 24 GND CTL1 RX1 Shutdown Mode Digital Control Receive Bypass Digital Control 25 22 GND 2 T/R Digital Control 26 GND GND GND 1 27 GND PA Input LNA and Bypass Switch Output 18 3.3 V Power Supply 220 pF 470 pF 15 14 Antenna Receive LNA and Bypass Switch Input S2127 Figure 23.
