Press Release Summary:
Intended for 75 Ohm systems operating up to 1 GHz, MAAD-008866 integrates TTL/CMOS compatible driver and offers parallel and serial control with power-up state function. This 6-bit, 0.5 dB step digital attenuator consumes 4 ÂµA typ @ 5 V (steady state) and achieves insertion loss of 1.4 dB with typ input return loss of 18 dB from 5-1,000 MHz. Attenuation accuracy is Â±0.15 dB plus 4% of attenuation setting. Use helps maximize signal level control performance in gateways, nodes, and tuners.

M/A-COM Technology Solutions Introduces 6-Bit Digital Attenuator with Serial / Parallel Control for 75 Ohm Systems Operating up to 1 GHz
MAAD-008866 Includes TTL/CMOS Compatible Driver and Offers 0.5-dB Attenuation Steps to 31.5 dB
Lowell, MA - M/A-COM Technology Solutions Inc. (M/A-COM Tech) introduced today the MAAD-008866, a 6-bit, 0.5-dB step digital attenuator for 75 Ohm systems operating up to 1 GHz. This attenuator is ideal when high accuracy, low power consumption (4 microAmps typical at 5V, steady state) and low intermodulation products are required.
The MAAD-008866 includes an integrated TTL/CMOS compatible driver and offers parallel and serial control with a power-up state function. The device achieves an insertion loss of 1.4 dB with a typical input return loss of 18 dB from 5 MHz to 1,000 MHz. Attenuation accuracy is plus/minus 0.15 dB plus 4% of attenuation setting.
"The new digital attenuator enables broadband equipment manufacturers to maximize signal level control performance in home gateways, passive optical nodes, cable cards and RF tuners," said Graham Board, Global Product Manager, CATV products. "Made with our proven pHEMT process and 'green' over-mold packaging, the attenuator expands our Broadband/CATV product portfolio of 75 Ohm products that includes a variety of amplifiers, switches and multifunction ICs."
Engineering samples, sample boards and production devices are available now. The evaluation board part number is MAAD-008866-001SMB. The MAAD-008866 is sold in 13-inch, 3,000 piece reels.
