The Broadband 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 Broadband analog front-end is a compact analog RF front-end for the Iris-030 SDR platform that provides TDD/FDD switching capabilities for frequencies between 50 – 3800 MHz. No amplification, filtering, or frequency duplexing is implemented, allowing the use of all frequencies in either Time Division Duplex (TDD) or Frequency Division Duplex (FDD) mode for development, or the addition of external RF components to prototype custom systems.
In addition to providing design flexibility for new radio systems and technologies, the Broadband analog front-end hardware design is open-sourced, providing researchers and developers with a starting point for implementing their own custom Iris analog front-end.
For applications that require high-powered, filtered RF front ends, Skylark offers a line of other band-specific analog front ends built for specific 3GPP bands ideal for Massive MIMO and 5G.
