M/A-COM Technology Solutions Announces 1-Bit Digital Attenuator for CATV Applications
New GaAs Integrated Digital Attenuator Features Low Insertion Loss and 75 W Impedance
Lowell, MA - M/A-COM Technology Solutions Inc. (M/A-COM Tech), a leading supplier of high performance analog semiconductor solutions, introduced today a 1-Bit digital attenuator for CATV and set-top box (STB) front end applications. The MAAD-010305 is a 15 dB step GaAs MMIC digital attenuator. It is designed to condition cable input signals to the STB. The device is ideally suited for use where high accuracy, very low power consumption, and low intermodulation products are required.
"We are very pleased to continue the expansion of our 75 W product portfolio with the introduction of this highly linear, 15 dB digital attenuator," said Graham Board, Product Manager. "This device is ideally suited for use in high volume, cost sensitive customer premises equipment."
