Digital Attenuator, 15 dB, 4-Bit, TTL Driver, DC - 3 GHz V 3.00 AT-213 Features n Attenuation: 1 dB steps to 15 dB n Temperature Stability: ± 0.18 dB from –55°C to +85°C n n n n CR-11 Typical Low DC Power Consumption Hermetic Surface Mount Package Integral TTL Driver 50 Ohms Nominal Impedance Description M/A-COM’s AT-213 is a 4-bit, 1 dB step digital attenuator in a hermetically sealed ceramic 16-lead surface mount package. The AT-213 is ideally suited for use where high accuracy, fast switching, very low power consumption and low intermodulation products are required. Typical applications include dynamic range setting in a precision receiver circuits and other gain/leveling control circuits. Environmental screening is available.
