DATA SHEET SKY65352-11: 2.4 GHz Transmit/Receive Front-End Module with Integrated Low-Noise Amplifier Applications Description • 2.4 GHz ISM band radios Skyworks SKY65352-11 is a high-efficiency Front-End Module (FEM). The device contains a 2400 to 2500 MHz high efficiency transmit path and a low-noise receive path. • ZigBee® FEMs • IEEE 802.15.4 applications The transmit path consists of a high efficiency Power Amplifier (PA) and harmonic filter. The receive path contains a low current Low-Noise Amplifier (LNA). Features The transmit and receive paths are connected to a common Single-Pole, Double-Throw (SPDT) switch at both the input and output. • Transmit output power > +20 dBm • Receive path NF < 2.5 dB • High efficiency PA There is an internal balun that allows either the transmit input or the receive output to connect to a differential port. • Configurable transmit/receive paths The device is mounted in a 20-pin, 6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution. • Internal switching and control circuits • Internal RF match and bias circuits • Single DC supply = 3.3 V • All RF ports are internally DC blocked • Small footprint, MCM (20-pin, 6 x 6 mm) SMT package (MSL3, 260 °C per JEDEC J-STD-020) A block diagram of the SKY65352-11 is shown in Figure 1. The device package and pinout for the 20-pin MCM are shown in Figure 2. Figure 1.

SKY65352-11 Pinout – 20-Pin MCM (Top View) Technical Description Shut Down and T/R Switch Mode Control Pin 8 (SDN) is used to enable the device while pin 20 (T_R) enables transmit or receive mode. The following control logic is used to configure the transmit, receive, or shut down mode of the SKY65352-11: SDN (Pin 8) T_R (Pin 20) Mode High High Transmit mode High Low Receive mode Low Low Shut Down mode operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. The SKY65352-11 provides one RF differential port composed of the RF_P and RF_N pin signals (pins 5 and 6, respectively). The Smith chart shown in Figure 3 plots the impedance of the RF differential port. Typical performance characteristics are shown in Figures 4, 5, and 6. Package and Handling Information Bottom Center Paddle 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 bottom center paddles must be electrically grounded for proper RF performance. Customers should place adequate thermal vias under the ground paddles for optimum thermal performance. The Evaluation Board layout can be used as a guide for RF ground and thermal layout. The SKY65352-11 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. Electrical and Mechanical Specifications 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. Signal pin assignments and functional pin descriptions are described in Table 1.

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.
