SKY13381-374LF Block Diagram Small, MLPD (6-pin, 1.5 x 1.5 mm) Pb-free package (MSL1, 260 C per JEDEC J-STD-020) Description The SKY13381-374LF is a GaAs pHEMT Double-Pole, Double- Throw (DPDT) switch designed for 2.4 and 6.0 GHz, dual-band wireless LAN applications. The switch provides high linearity performance, low insertion loss, and high isolation in both frequency bands. Switching is controlled by two voltage inputs (V1 and V2). Depending on the logic voltage level applied to the control pins, the ANT1 and ANT2 pins connect to one of two switched RF outputs (RX or TX) through a low insertion loss path while maintaining a high isolation path to the alternate port. The switch is manufactured in a compact, 1.5 x 1.5 mm, 6-pin exposed pad plastic Micro Leadframe Package Dual (MLPD) 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.
