SKY53745-21

Sky5® LB/MB/HB Diversity Receive Module

The SKY53745-21 is a low-band (LB)/mid-band (MB)/high-band (HB) diversity receive module to be used in a cellular mobile device. The device supports cellular diversity receiver functions. The SKY53745-21 is part of our Sky5® product portfolio.

The diversity module supports all key 2 and 3 carrier aggregation band combinations.

High-performance, multi-gain mode LNAs are integrated enabling compatibility to next generation LNA-less LTE transceivers. The SKY53745-21 is compatible with 3GPP GSM, WCDMA, LTE, LTE-A and 5G standards and includes filters for the following service bands: B8, B26/5/18/19, B28A/B, B3, B39, B25(2), B34, B66(1/4), B40, B41(38), and B7.
