EBS/BRS/CBRS interchangeable analog front-end

Iris® 2T x 2R TDD analog radio front-end for EBS/BRS/CBRS operation in 2495 – 2690 MHz and 3550 – 3700 MHz bands.

SKU IRIS-FE-03-CBRS Category

The Iris CBRS/BRS analog front-end is part of the Iris family of software-defined radio (SDR) modules designed to support coherent real-time wireless Multiple-In Multiple-Out (MIMO) operation with hundreds of coherent digital radio chains. The unique modular design of Iris draws on years of massive MIMO research, enabling scalable MIMO systems with minimal cabling.

The CBRS/BRS analog front-end is a compact analog RF front-end for the Iris-030 SDR platform that provides amplification and filtering capabilities for one or more 3GPP bands between 2495 – 2690 MHz and 3550 – 3700 MHz, ideal for dense, Time Division Duplex (TDD) Massive MIMO implementations. It is optimally sized for large-scale MIMO arrays in a company form factor at 3700 MHz.

Designed to directly attach to an Iris-030 SDR module and various internal antennas from Skylark and customers, the design of the CBRS/BRS analog front-end enables high-order MIMO systems with minimal cabling and hundreds of coherent radios.
