High-speed converters in stock at Richardson RFPD

The AD9081 and AD9082 mixed-signal front-ends combine high-performance analogue and digital signal processing and allow designers to install multiband radios in the same footprint as single-band radios.

By shifting more of the frequency translation and filtering from the analogue to the digital domain, the AD9081/2 provides designers with the software configurability to customise radios. 

ADI’s MxFE platform processes more of the RF spectrum band and embeds DSP functions on-chip to enable the user to configure the programmable filters and digital up- and down-conversion blocks to meet specific radio signal bandwidth requirements.

This results in a 10X power reduction compared to architectures that perform RF conversion and filtering on the field-programmable gate array, while freeing up valuable processor resources or allowing designers to use a more cost-effective FPGA. 

The new AD9081/2 MxFE platform is suitable for a range of applications, including: 

• Wireless communications infrastructure
• Microwave point-to-point, E-band and 5G mmWave
• Broadband communications systems
• DOCSIS 3.1 and 4.0 CMTS
• Phased array radar and electronic warfare
• Electronic test and measurement systems 

The AD9081 MxFE includes four 16-bit, 12 gigasample-per-second RF digital-to-analogue converter cores and four 12-bit, 4 GSPS RF analogue-to-digital converter cores. The AD9082 MxFE includes four 16-bit, 12 GSPS RF DAC cores and two 12-bit, 6 GSPS RF ADC cores.

Both devices feature eight transmit lanes and eight receive lanes that support 24.75 Gbps/lane JESD204C or 15.5 Gbps/lane JESD204B standards. They are available in 15 mm x 15 mm BGA packages.
