Description

The SKY13384-350LF is a symmetrical, single-pole, four-throw

(SP4T) switch. The switch is intended for

GSM/CDMA/WCDMA/TD-SCDMA/TD-LTE cellular infrastructure

applications. The impedance of the RF ports in isolation is 50

Ω.

The SKY13384-350LF is manufactured using Skyworks state-of-

the-art GaAs pHEMT process. The SKY13384-350LF features

integrated logic that uses only two control lines for switch

operation.

The SKY13384-350LF SP4T switch is provided in a compact Quad

Flat No-Lead (QFN) 3 x 3 mm 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.
