DATA SHEET SKY65346-21: 900 MHz Transmit/Receive Front-End Module Applications Description • Automated meter reading The SKY65346-21 is a high performance transmit/receive (T/R) Front-End Module (FEM) ideally suited for use in 900 MHz Industrial, Scientific, and Medical (ISM) applications. Features A double-pole, double-throw (DPDT) switch allows the device to select between two antenna ports (ANT1 and ANT2 pins) for the transmit or receive path. A single-pole, double-throw (SPDT) switch selects which signal path is routed to the transceiver port (RFIO pin). The receive path has a Low-Noise Amplifier (LNA) bypass switch. • Externally available bias circuits • Control logic • Cascaded receive gain: 12.4 dB • Cascaded Noise Figure: 2.4 dB • Transmit power: +26 dBm • Single DC supply • Shutdown mode • Small, MCM (26-pin, 5 x 5 mm) package (MSL3, 260 °C per JEDEC J-STD-020) Skyworks Green™ products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of Green™, document number SQ04-0074. The Power Amplifier (PA) and LNA biasing can be independently controlled with an external bias resistor. The device has a shutdown mode to minimize power consumption. All eight operating modes are controlled using three digital input pins (CTL1, CTL2, and CTL3). The SKY65346-21 T/R FEM is provided in a compact, 26-pin 5 x 5 mm Multi-Chip Module (MCM). A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2.

In this mode, the SKY65346-21 amplifies the received signal at antenna port 2 through the LNA. Functional Description The SKY65346-21 provides input and output amplifier stages, and is internally matched for optimum efficiency. An active bias circuit provides both input and output stages with excellent gain tracking over temperature and voltage variations. The module operates with positive DC voltages, and maintains high efficiency and good linearity. The nominal operating voltage is 3.3 V for maximum power. The PA and LNA biasing can be independently controlled with an external bias resistor. • Transmit ANT1. In this mode, the transmit path provides an harmonic filter and high efficiency PA on the Antenna 1 Port. • Transmit ANT2. This is the same mode of operation as Transmit ANT1 except that the output is the Antenna 2 Port. • Shut down. In this mode, the PA and LNA are powered down for minimal current consumption and low leakage current (<1 μA). Table 2 provides the control logic for each of the eight operational modes. Operational Modes By using three control signals (CTRL1, CTRL2, and CTRL3), the SKY65346-21 can be configured to one of eight operational modes: Electrical and Mechanical Specifications • Receive ANT1 bypass. In this mode, a low-loss broadband, bidirectional RF path allows easy switching of the signal between the transceiver and antenna port 1. The absolute maximum ratings of the SKY65346-21 are provided in Table 3 and the recommended operating conditions in Table 4. Electrical characteristics for the SKY65346-21 are provided in Table 5 through Table 10. • Receive ANT2 bypass. In this mode, a low-loss broadband, bidirectional RF path allows easy switching of the signal between the transceiver and antenna port 2. Typical performance characteristics of the SKY65346-21 are illustrated in Figures 3 through 27. • Receive ANT1. In this mode, the SKY65346-21 amplifies the received signal at antenna port 1 through the LNA. 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. Note 2: Antenna port load VSWR is limited by voltage. An open load condition will not damage 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.

Receive Path OIP3 (ANT1/ANT2 to ASW_RX) vs Frequency Over Temperature Evaluation Board Description The SKY65346-21 Evaluation Board is used to test the performance of the SKY65346-21 FEM. An Evaluation Board schematic diagram is provided in Figure 28. An assembly drawing for the Evaluation Board is shown in Figure 29 and the layer detail is provided in Figure 30. Package Dimensions The PCB layout footprint for the SKY65346-21 is provided in Figure 31. Typical case markings are shown in Figure 32. Package dimensions for the 26-pin MCM are shown in Figure 33, and tape and reel dimensions and provided in Figure 34. Circuit Design Configurations The following design considerations are general in nature and must be followed regardless of final use or configuration: 1. Paths to ground should be made as short as possible. 2. The ground pads of the SKY65346-21 have special electrical and thermal grounding requirements. These pads are 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 pads to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required. 3. Two external output bypass capacitors (10 nF and 100 pF) are required on pin 23 (VCC2). The same two capacitor values are also required on pin 9 (VCC1). The capacitors should be placed in parallel between the supply line and ground. Package and Handling Information 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. THE SKY65346-21 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 the Skyworks Application Note, PCB Design & SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. 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. 4. Pins 9 and 23 (VCC1 and VCC2, respectively) may be connected together at the supply. NOTE: A poor connection between the slug and ground increases junction temperature (TJ), which reduces the lifetime of the device.
