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.
