SKY13445-368LF Block Diagram Description The SKY13445-368LF is a pHEMT GaAs switch. The device includes a Single-Pole, Triple-Throw (SP3T) switch for 2 GHz WLAN transmit, receive, and Bluetooth functions, and a SinglePole, Double-Throw (SP2T) switch for 5 GHz transmit and receive functions. Any of the RF ports can be used for any RF function regardless of the port name. The SKY13445-368LF requires external DC blocking capacitors on all RF ports. Both the SP3T and SP2T switches are fabricated on the same substrate. The active path is selected with five positive voltage control lines (V1, V2, and V3 for low band switching, and V4 and V5 for high band switching). In low band mode, the high band paths are in isolation by applying a low voltage to the two control lines, V4 and V5. The switch is manufactured in a compact, 2 x 2 mm, 12-pin exposed pad plastic Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2.

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 SKY13445-368LF are provided in Table 2. Electrical specifications are provided in Tables 3 and 4. The state of the SKY13445-368LF is determined by the logic provided in Table 5. Typical performance characteristics of the SKY13445-368LF are illustrated in Figures 3 to 10.
