Description

The SKY13745-21 is an LNA diversity module to be used in a

cellular mobile device. It supports cellular diversity receiver and

localization service receiver functions.

It is compatible with 3GPP GSM, WCDMA, and LTE standards and

supports the following service bands: B26, B8, B20, B1/4, B3,

and B7 for the cellular part.

The SKY13745-21 is packaged in a small 3

 5  0.7 mm,

29-lead surface-mount package. The part is controlled by an

integrated Mobile Industry Processor Interface (MIPI) decoder.

There are separate control registers for independent control of

low band, middle band, and high band. The part can operate over

the temperature range of –30

C to +85 C.

A functional block diagram is shown in Figure 1.
