AT-107

Digital Attenuator, 31.5 dB, 6-Bit, TTL Driver, DC - 2 GHz V 4.00 AT-107 Features n Attenuation: 1 dB steps to 31.5 dB n Temperature Stability: ± 0.18 dB from –55°C to +85°C n n n n CR-13 Typical Low DC Power Consumption Hermetic Surface Mount Package Integral TTL Driver 50 Ohm Nominal Impedance Description M/A-COM’s AT-107 is a GaAs FET 6-bit digital attenuator with a 1 dB minimum step size and 31.5 dB total attenuation. This attenuator and integral TTL driver is in a hermetically sealed ceramic 24-lead surface mount package. The AT-107 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. Environmental screening is available. Contact the factory for information.
