描述 Description

The SKY13455-31 is a Single-Pole, Twelve-Throw (SP12T)

antenna switch with integrated GSM transmit harmonic filter. The

SKY13455-31 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, TRX2, and

TRX4) have been specifically designed to provide optimal LTE

Band 13 performance. The switch exhibits an excellent triple beat

ratio and 2nd/3rd order modulation distortion performance.

Switching is controlled by an integrated MIPI 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 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.

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
