SKY13491-21数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

The SKY13491-21 is a Single-Pole, Fourteen-Throw (SP14T)antenna switch with an integrated Mobile Industry ProcessorInterface (MIPI®) controller. Using an advanced switchingtechnology, the SKY13491-21 maintains low insertion and highisolation, which makes it an ideal choice for UMTS, CDMA2000,EDGE, GSM, and LTE applications.

The design features two dedicated GSM transmit ports and threededicated ultra low-loss TRX ports. The switch also has anexcellent triple beat ratio and 2nd/3rd Order IntermodulationDistortion (IMD2/IMD3) performance.

Switching is controlled by the MIPI decoder. There is an externalMIPI select pin that enables how the switch responds to powermode triggers. When this pin is grounded, the switch responds toany of the power mode triggers. When this pin is left open, theswitch responds to individual power mode triggers. No externalDC blocking capacitors are required on the RF paths as long as noDC voltage is applied.

The SKY13491-21 is manufactured in a compact,2.5 x 2.9 x 0.8 mm, 22-pin surface mount Multi-Chip Module(MCM) package.

特性 Features

• Dedicated Band 7 TRX ports: 0.90 dB insertion loss @ 2.7 GHz
