SKY13455-31中文资料High Throw Count (>4T) Switches / Antenna Switch Modules (ASM)数据手册Skyworks规格书

描述 Description

The SKY13455-31 is a Single-Pole, Twelve-Throw (SP12T)antenna switch with integrated GSM transmit harmonic filter. TheSKY13455-31 maintains a high linearity, high isolation, and lowinsertion loss performance, which makes it an ideal choice forUMTS, CDMA2000, EDGE, GSM, and LTE applications.

The design features two dedicated GSM transmit ports. Theremaining ten ports are suitable for WCDMA transmit/receive andGSM receive functions. Three transmit ports (TRX1, TRX2, andTRX4) have been specifically designed to provide optimal LTEBand 13 performance. The switch exhibits an excellent triple beatratio and 2nd/3rd order modulation distortion performance.

Switching is controlled by an integrated MIPI interface. Dependingon the logic applied to the decoder, the antenna pin is connectedto one of 12 switched RF ports using a low insertion loss path,while the paths between the antenna pin and the other RF pinsare in a high isolation state. No external DC blocking capacitorsare required on the RF paths.

The SKY13455-31 is manufactured in a compact,3.2 x 2.5 x 0.8 mm, 22-pin surface mount Multi-Chip Module(MCM) package.
