Digital Attenuator, 50 dB, 6-Bit, TTL Driver, DC - 2.0 GHz AT65 - 0106
Description M/A-COM's AT65-0106 is a GaAs FET 6-bit digital attenuator with a 1 dB minimum step size and a 50 dB total attenuation range. This device is in a SOIC-24, wide body plastic surface mount package. The AT65-0106 is ideally suited for use where accuracy, fast speed, very low power consumption and low costs are required. Package outline conforms to JEDEC standard MS-013AD.
