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, April 27, 2011 - 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
"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
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.
Technical support is also available from M/A-COM Tech's applications engineers at 978.656.2539. Datasheets and
