Description

The SKY13431-374LF is a GaAs pHEMT single-pole, double-throw

(SPDT) high-power switch with 50 Ω terminated outputs. The

high-linearity performance and low insertion loss achieved by the

SKY13431-374LF make it an ideal choice for WiMAX and higher

power WLAN applications such as access points.

This part is designed for use in WLAN systems using discrete

power amplifier (PA) and low-noise amplifier (LNA)

implementations. The 50 Ω impedance of the switch in the “off”

state ensures good isolation regardless of the match to which the

switch is connected.

The SKY13431-374LF is manufactured in a compact,

1.5 x 1.5 mm, 6-pin Dual Flat No-Lead (DFN) 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
