Wideband configurable RF transceiver offers 100 MHz BW to 6 GHz

May 23, 2016 // By Graham Prophet
Analog Devices has extended the features and specification of its AD9361 transceiver chip, with the AD9371 integrated wideband RF transceiver, placing it at the centre of a package it has called RadioVerse, to offer versatile solutions for wireless infrastructure, aerospace and defence, and instrumentation applications.

The aims of the RadioVerse programme, says ADI, are to solve more complex radio problems, and to relieve non-specialists of radio problems: increasingly, the radio link may be jut one part of a complex system architecture and it is essential the radio portion is executed quickly. Accordingly, the programme comprises integrated transceiver technologies, a design environment, and market-specific technical expertise intended to take radio designs from concept to creation quickly. Transceiver technologies reduce radio size, weight and power (SWaP), while the design environment offers board support packages, software and tools to simplify and accelerate radio development across a range of applications.


AD9371 is versatile, carrier-grade, system-on-chip radio with RF tuning range of 300 MHz to 6 GHz, 100-MHz signal bandwidth, and power consumption of less than 5W under standard operating conditions. It has been configured expressly for wideband applications (hence much higher power than the 9361); the company hints that future variants on the same theme will bring similar versatility to narrowband and low power sockets. It replaces or eliminates as many as 20 discrete radio components and can be used as a common design platform across multiple applications and standards, increasing R&D efficiency and reducing time-to-market of the end product.

The 9371 contains, among other blocks, two independent receive paths with 100 MHz bandwidth, capable of FDD or TDD operation; two transmitters with max large signal BW of 100MHz and max synthesis BW of 250 MHz; and further observation and sniffer receive paths (that you might use for setting digital pre-distortion, for example) with 250 MHz BW. On the baseband side all I/O is purely digital, with JESD204B interfaces; auxiliary DACs, ADCs and GPIO are provided. A spokesman commented that most applications of the device are expected to be in fixed-function sockets; although capable of being applied to reconfigurable, software-defined-radio tasks, most such applications will likely lie in defence or T&M areas.
