USA: Analog Devices Inc. has introduced an industry first 2.8-GSPS dual 16-bit converter for 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 while enabling designers to support emerging E-band (71-76 GHz and 81-86 GHz) frequencies being adopted by wireless carriers to support steadily increasing demand for 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 complex 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 exceptional noise performance of -163dBm/Hz that provide high quality synthesis of wideband signals.
The industry-leading combination of speed and noise performance results in faster, cleaner data transmission and reduces infrastructure costs by allowing wireless carriers to space point-to-point microwave repeaters farther apart.
