M/A-COM Announces 1-Bit Digital Attenuator for CATV Applications
M/A-COM Technology Solutions introduced 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 O 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.”
The table below outlines typical part number performance:
|Input Return Loss||dB||14|
|Output Return Loss||dB||14|
|CTB (157 Channels, PIN = 35 dBmV/Ch)||dBc||70|
|CSO(157 Channels, PIN = 35 dBmV/Ch)||dBc||66|
The MAAD-010305 is fabricated as a monolithic GaAs integrated circuit using a mature pHEMT process. The process features full chip passivation for performance and reliability. The attenuator is designed for operation from DC to 1.1 GHz. It is packaged in a RoHS compliant lead free SOT-25, five-lead surface mount plastic package. The MAAD-010305 is characterized by low insertion loss and allows for positive and negative voltage control, complimented by 75 O impedance.
Production quantities and samples of MAAD-010305 are available from stock. Final datasheets and additional product information can be obtained from the M/A-COM Tech website at www.macomtech.com
