Rx Diversity FEM with Carrier Aggregation (B26, B8, B20, B1/4, B3, and B7)

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 x 5 x 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.
