描述 Description

The SKY13438-374LF is a pHEMT GaAs 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.
