描述 Description

The SKY13411-374LF is a pHEMT GaAs double-pole, doublethrow

(DPDT) switch designed for dual-band wireless LAN

applications. The switch provides high linearity performance, low

insertion loss, and high isolation.

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
