Description

The SKY13446-374LF is a pHEMT GaAs I/C antenna switch.

Switching between the antenna and TX or RX ports is

accomplished with two control voltages. The low-loss, high

isolation, high linearity, small size and low cost make this switch

ideal for all dual-band WLAN systems that operate at 2.4 to

2.5 GHz and 4.9 to 5.9 GHz.

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
