LB / LMB / MB / HB and 4x4 MIMO Diversity Receive Module
The SKY53735-21 is a low-band (LB)/low-mid-band (LMB) /
mid-band (MB) / high-band (HB) diversity receive module to be
used in a cellular mobile device. The device supports cellular
diversity receiver functions and is scalable to support 4x4 MIMO
regional and roaming band requirements.
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 SKY53735-21 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, B3, B39, B25(2), B34, B66(1/4), B40, B41(38), and B7.
