Description

The SKY13380-350LF is a symmetrical, single-pole, four-throw (SP4T) switch. The device is designed for broadband, high power switching applications that demand high linearity and low insertion loss. This is a general purpose switch optimized for a variety of multimode applications such as GSM/WCDMA/EDGE. The switch is manufactured using Skyworks state-of-the-art pHEMT process. The SKY13380-350LF features integrated logic that uses only two control lines for switch operation. The low current consumption makes the device suitable for battery-operated applications. The SKY13380-350LF SP4T switch is provided in a compact Quad Flat No-Lead (QFN) 3 x 3 mm 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.
