DATA SHEET SKY65336-11: 2.4 GHz Transmit/Receive Front-End Module with Integrated LNA Applications Description • 2.4 GHz ISM band radios Skyworks SKY65336-11 is a high-efficiency Front-End Module (FEM) for ZigBee and other 2.4 GHz ISM band applications. The small 8 x 8 mm Multi-Chip Module (MCM) contains a 2400-2500 MHz high-efficiency transmit path and a low-noise linear receive path. • ZigBee® FEMs • IEEE 802.15.4 applications The transmit path consists of an harmonic filter and high efficiency Power Amplifier (PA) capable of providing +20 dBm of power at the antenna port. Also included is an internal balun to allow use of differential input signals. Features • Transmit output power > +20 dBm • Receive NF < 3 dB The receive path contains a high isolation Transmit/Receive (Tx/Rx) switch, Low Noise Amplifier (LNA), and balun for low noise differential output. • High efficiency PA • Programmable transmit power levels • Configurable transmit/receive paths The device is mounted in a 28-pin, 8 x 8 mm MCM SurfaceMounted 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 = 3.0 V • Interfaces seamlessly with Ember EM250 and EM260 ZigBee transceivers A block diagram of the SKY65336-11 is shown in Figure 1. The device package and pinout for the 28-pin MCM are shown in Figure 2. • All RF ports are internally DC blocked • Small footprint, MCM (28-pin, 8 x 8 mm) SMT package (MSL3, 260 °C per JEDEC J-STD-020) Figure 1.

SKY65336-11 Pinout – 28-Pin MCM (Top View) Technical Description Bottom Center Paddles Transmit/Receive (Tx/Rx) Enable 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 (see Figures 3 and 4) can be used as a guide for RF ground and thermal layout. Pin 27 (TX_EN) and pin 12 (RX_EN) are used to enable the transmit and receive port, respectively. Tx/Rx Switch Pin 28 (T_R) is used to control the Tx/Rx switch. Electrical and Mechanical Specifications Tx/Rx Enable and Tx/Rx Switch Mode Control The following control logic is used to configure the transmit or receive mode of the SKY65336-11: TX_EN RX_EN T_R Mode High Low High Transmit mode Low High Low Receive mode Signal pin assignments and functional pin descriptions are described in Table 1. The absolute maximum ratings of the SKY65336-11 are provided in Table 2. Recommended operating conditions are noted in Table 3 and electrical specifications are provided in Table 4. Typical performance characteristics of the SKY65336-11 are shown in Figures 3 through 12. High Power and Low Power Modes High power mode output is 20 dBm and low power mode output is 10 dBm.

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.
