Analog Devices has introduced 12-bit and 10-bit mixed-signal front-ends (MxFEs) that aim to reduce power and board space for developers of wireless infrastructure and portable radio equipment. The company reports that its 12-bit AD9963 and 10-bit AD9961 MxFEs use 40 percent less power and 25 percent less printed-circuit board area than competing devices. These digital to analog converters (DACs) are targeted at cost-sensitive wireless equipment, such as femtocell and picocell base stations that require dual transmit-and-receive functions.
SNR (signal-to-noise ratio) = 66.5 dB
ACLR (adjacent-channel leakage ratio) = 72 dBc
Power = 425 mW at maximum sample rates
Transmit path power consumption = less than 100 mW at 170 MSPS @ 1.8 V
Receive path power consumption = less than 350 mW at 100 MSPS @ 1.8 V
