Description
M/A-COM’s AT-267 is a 1-bit, 15-dB step GaAs MMIC digital attenuator in a low cost SOT-25, 5 lead surface mount plastic package. The AT-267 is ideally suited for use where high accuracy, very low power consumption and low intermodulation products are required. Typical applications include wireless handsets, base stations, wireless LAN equipment, GPS receivers and any RF applications with automatic gain/level control circuits. The AT-267 is fabricated as a monolithic GaAs integrated circuit using a mature PHEMT process. The process features full chip passivation for performance and reliability.
