The migration towards 2×2 MIMO and 4×4 MIMO will push OEMs to meet the challenges of thermal dissipation, RF output power and size/weight of remote radio units. The RRUS 11 represents a compact form factor to address 2×2 MIMO LTE functionality.

EJL Wireless Research is announcing a new report within its proprietary DNA-I series, an Ericsson CDMA/LTE 1900MHz B25 80W RRUS 11 unit.

“This is our first opportunity to look into the 2×2 MIMO design philosophy for Ericsson’s latest generation remote radio unit and has allowed us to see design changes from the prior generation non-MIMO RRUS 01. The RRUS 11 contains two complete radio transceivers, two power amplifiers and two duplexer filters to support 2×2 MIMO functionality. The RRUS 11 is part of the RBS6601 Main/Remote BTS system and is the multi-standard radio architecture version of Ericsson’s remote radio units that supports GSM, CDMA, W-CDMA and LTE technologies,” said founder and President, Earl Lum.

EJL Wireless Research continues to lead the wireless market research segment with innovative and cutting edge research such as its DNA-I series of products.

“We continue to be excited in having the opportunity to showcase the latest generation remote radio units, RF transceiver modules, BTS antennas, femtocells and base stations from major wireless equipment OEMs as part of our DNA-I program,” says Lum.

The following semiconductor & passive component suppliers are included in this report: Analog Device, Anaren Microwave, Coilcraft, Fairchild Semiconductor, Freescale Semiconductor, Hittite Microwave, Maxim Integrated Products, Micron Technology, Nippon Chemi-Con, Nichicon, NXP Semiconductors, STMicroelectronics, TDK-EPCOS, Texas Instruments, and Vishay Semiconductors.
