Digital Attenuator
MACOM’s AT20-0273 is a GaAs FET digital attenuator with a 16 dB minimum step size and 32 dB total attenuation. This attenuator and integral TTL driver is in a sealed ceramic 16-lead surface mount package. The AT20-0273 is ideally suited for use where accuracy, fast switching, very low power consumption and low intermodulation products are required. Typical applications include dynamic range setting in precision receiver circuits and other gain/leveling control circuits. Available with enhanced performance as fully hermetic version. Environmentally screenable as P/N AT-273-PIN.
