DATA SHEET SKY65337-11: 2.4 GHz Transmit/Receive Front-End Module Applications Description • 2.4 GHz ISM band radios Skyworks SKY65337-11 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 24002500 MHz high-efficiency transmit path and a low-loss bidirectional path. The bidirectional path can be used to directly connect the antenna port to a directional RF port. • ZigBee® FEMs • IEEE 802.15.4 applications Features 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. • Transmit output power > +20 dBm • Bidirectional path NF < 2 dB • High efficiency PA The bidirectional path contains a high isolation transmit/receive (T/R) switch and balun for low-noise differential output. The bidirectional path can be used for either transmit or receive. • Programmable transmit power levels • Configurable transmit/bidirectional paths • Internal switching and control circuits The differential output receiver port is bidirectional and can be used to operate the module in a low-power transmit mode. • Internal RF match and bias circuits • Single DC supply = 3.0 V • Interfaces seamlessly with Ember EM250 and EM260 ZigBee transceivers • 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) 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. A block diagram of the SKY65337-11 is shown in Figure 1. The device package and pinout for the 28-pin MCM are shown in Figure 2. Figure 1.

SKY65337-11 Pinout – 28-Pin MCM (Top View) Technical Description Bottom Center Paddle Transmit/Receive (T/R) 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. T/R Switch Pin 28 (T_R) is used to control the T/R switch. Tx/ Rx Mode Control with limited Fast Control Lines T/R Enable and T/R Switch Mode Control If only one fast analog control line is available for module configuration, users can connect the RX_EN pin to 3 V, and connect the TX_EN and T_R control lines together as follows: The following control logic is used to configure the transmit or receive mode of the SKY65337-11: TX_EN T_R RX_EN Module Configuration High High Transmit mode Low High Receive mode TX_EN RX_EN T_R Mode High High Low High Transmit mode Low Low High Low Receive mode Electrical and Mechanical Specifications High Power and Low Power Modes High power mode output is 20 dBm and low power mode output is 10 dBm. Pin 26 (TX_HLB) sets the transmit path in high power or low power mode according to the following logic: TX_HLB State Low High power mode High Low power mode Signal pin assignments and functional pin descriptions are described in Table 1. The absolute maximum ratings of the SKY65337-11 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4.

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.
