Use an agile RF transceiver in an adaptive SDR communication system for aerospace and defense
development support through documentation and downloadable software packages. Developers using the development hardware mentioned above can proceed with prototyping and development based on Analog Devices’ product line software or open-source software packages. This article limits the following discussion to product line software. For more information about the open-source development methodology, see Analog Devices’ ADRV9001/2 Prototyping Platform User Guide. Analog Devices stipulates that the term “ADRV9001” in the company’s support documentation is meant as a family designator encompassing the ADRV9002 and other members of the ADRV9001 family. Consequently, references to ADRV9001 in the text or figures below apply to the ADRV9002 device that is the focus of this article.

and hardware interfaces, as well as clock and multichip synchronization (MCS) distribution. The cards connect through their FMC connector to an FPGA motherboard, such as AMD’s ZCU102 evaluation board for power and application control. Analog Devices provides a complete schematic and bill of materials (BOM) for its ADRV9002NP radio cards in its support package. The schematic and BOM provide an effective starting point for custom hardware development for most applications. Some applications require an additional RF front-end to meet specific signal conditioning requirements. For these applications, developers only need a few additional components to complete their design (Figure 4). In this example, developers can quickly implement a suitable RF front-end using the following power management components from
Analog Devices: ■ ADRF5160 RF switch ■ HMC8411 low noise amplifier (LNA) ■ ADMV8526 digitally tunable bandpass filter ■ HMC1119 RF digital step attenuator (DSA) ■ HMC8413 driver amplifier ■ HMC8205B PA
Analog Devices provides comprehensive software
