Sky5® LB/LMB/MB/HB and 4x4 MIMO Diversity Receive Module

The SKY53735-61 is a low-band (LB)/low-mid-band (LMB)/mid-band (MB)/high-band (HB) diversity receive module for cellular mobile devices. The device supports cellular diversity receiver functions and is scalable to support 4x4 MIMO regional and roaming band requirements. The SKY53735-61 is part of our Sky5® product portfolio.

The diversity module supports all key 2, 3, and 4 carrier aggregation band combinations. High-performance, multi-gain mode LNAs are integrated enabling compatibility to next generation LNA-less LTE transceivers.

The SKY53735-61 is compatible with 3GPP GSM, WCDMA, LTE, LTE-A and 5G standards and includes filters for the following service bands: B71, B29, B12/ 13/17, B14, B28A, B28B, B20, B8, B26/5/18/19, B32, B3, B39, B25(2), B34, B66(1/4), B30, B40, B41(38), and B7.
