Description
M/A-COM’s AT90-0001 is a GaAs FET 5-bit digital attenuator with an integral TTL driver. Step size is 1.0 dB providing 31 dB total attenuation range. This device is in a 32 lead FQFP-N surface mount package. Due to superior grounding techniques this digital attenuator offers superior performance to 6 GHz. The AT90-0001 is ideally suited for use where accuracy, fast speed, very low power consumption and low costs are required.
