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-ofthe-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. Si...
