描述 Description

Please note: SKY13413-488LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY13488-21

The SKY13413-488LF is a Single Pole, Twelve Throw (SP12T) antenna switch with integrated GSM transmit harmonic filter. The SKY13413-488LF maintains a high linearity, high isolation, and low insertion loss performance, which makes it an ideal choice for UMTS, CDMA2000, EDGE, GSM, and LTE applications.

The design features two dedicated GSM transmit ports. The remaining ten ports are suitable for WCDMA transmit/receive and GSM receive functions. Three transmit ports (TRX1, TRX3, and TRX7) have been specifically designed to provide optimal LTE Band 13 performance without requiring external harmonic filters to meet system requirements. The switch exhibits an excellent triple beat ratio and 2nd/3rd order modulation distortion performance.

Switching is controlled by an integrated GPIO interface. Depending on the logic applied to the decoder, the antenna pin is connected to one of 12 switched RF ports using a low insertion loss path, while the paths between the antenna pin and the other RF pins are in a high isolation state. No external DC blocking capacitors are required on the RF paths.

The SKY13413-488LF is manufactured in a compact, 2.6 x 3.4 mm, 26-pin surface mount Quad Flat No-Lead (QFN) package.
