SKY13352-337LF Block Diagram Description J1 12 11 The device provides high linearity, low insertion loss, and high isolation. Switching is controlled by four control voltage inputs (V1, V2, V3, and V4). Depending on the logic voltage level applied to the control pins, the four RF ports (J1, J2, J3, and J4) are connected together using a low insertion loss path, while maintaining a high isolation path to the alternate ports. All of the necessary DC blocking capacitors are integrated on die for all RF ports, which eliminates the need to add external blocking capacitors. N/C N/C The SKY13352-337LF is a GaAs pHEMT Double-Pole, DoubleThrow (DPDT) switch designed for 4.5 to 6.0 GHz diversity WLAN applications that use two antennas for both transmit and receive paths. 10 J3 2 8 J4 V4 3 7 V3 4 5 6 N/C V2 J2 9 N/C V1 1 The SKY13352-337LF is provided in a 3 x 3 mm, 12-pin Quad Flat No-Lead (QFN) package.

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. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13352-337LF are provided in Table 2. Electrical specifications are provided in Table 3. The state of the SKY13352-337LF is determined by the logic provided in Table 4. Typical performance characteristics are illustrated in Figures 3, 4, and 5.
