Analog Devices on Wednesday said 2.8-GSPS dual 16-bit converter achieves up to 70 percent higher signal bandwidth than competing devices.

The company is targeting telecommunications system manufacturers that require microwave frequencies in point-to-point wireless backhaul equipment.

The 16-bit AD9136 and 11-bit AD9135 dual D/A converters achieve up to 70 percent higher signal bandwidth than competing devices.

Analog Devices said the new converters enable designers to support E-band (71-76 GHz and 81-86 GHz) frequencies being adopted by wireless carriers to support high-speed mobile voice and data transfers. The new converters have a maximum sample rate of 2.8 GSPS, which allows multicarrier generation up to the Nyquist frequency.

The AD9136/5 D/A converters support input data rates of up to 2.12 GSPS per D/A converter using a flexible, 8-lane, 10.6 Gbps JESD204B interface. The new devices achieve better than -80dBc spurious-free dynamic range (SFDR) and have noise performance of -163dBm/Hz, said Analog Devices.

The AD9136/5 converters require 1.4 W of power under full operating conditions and integrate a low-noise PLL (phase-locked loop), which lowers bill of materials costs and simplifies system design by eliminating the need for a high-performance source clock.

The new converters also include integrated interpolation filters with selectable interpolation factors of 1, 2, 4, and 8.
