DATA SHEET SKY65343-11: 2.4 GHz Transmit/Receive Front-End Module Applications Description Skyworks SKY65343-11 is a high-efficiency Front-End Module 2.4 GHz ISM band radios (FEM) for ZigBee and other 2.4 GHz ISM band applications. The ZigBee FEMs small, IEEE 802.15.4 applications 6 x 6 mm Multi-Chip Module (MCM) contains a 2400 to 2500 MHz high-efficiency transmit path and a low-loss bidirectional path. The bidirectional path can be used to directly connect the antenna Features port to a directional RF port. Transmit output power > +20 dBm The transmit path consists of an harmonic filter and high efficiency Power Amplifier (PA) capable of providing +20 dBm of Bidirectional path NF < 1.6 dB power at the antenna port. Also included is an internal balun to High efficiency PA allow use of differential input signals. Programmable transmit power levels The bidirectional path contains a high isolation transmit/receive Configurable transmit/bidirectional paths (T/R) switch and balun for low-noise differential output. The bidirectional path can be used for either transmit or receive. Internal switching and control circuits The differential output receiver port is bidirectional and can be Internal RF match and bias circuits used to operate the module in a low-power transmit mode. Single DC supply = 3.3 V The device is mounted in a 20-pin, 6 x 6 mm MCM Surface- Interfaces seamlessly with Ember EM250 and EM260 ZigBee Mounted Technology (SMT) package, which allows for a highly transceivers manufacturable low-cost solution. All RF ports are internally DC blocked A block diagram of the SKY65343-11 is shown in Figure 1. The Small footprint, MCM (20-pin, 6 x 6 mm) SMT package (MSL3, device package and pinout for the 20-pin MCM are shown in 260 C per JEDEC J-STD-020) Figure 2. Figure 1.

Instructions on the High High Transmit mode shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems High Low Receive mode related to moisture absorption may occur when the part is Low Low Shut Down mode subjected to high temperature during solder assembly. The SKY65343-11 is rated to Moisture Sensitivity Level 3 (MSL3) Bottom Center Paddle at 260 C. It can be used for lead or lead-free soldering. For The bottom center paddles must be electrically grounded for additional information, refer to Skyworks Application Note, PCB proper RF performance. Customers should place adequate Design and SMT Assembly/Rework Guidelines for MCM-L thermal vias under the ground paddles for optimum thermal Packages, document number 101752. performance.
