MAAD-009195 Constant Phase Digital Attenuator Rev. V2 15.5 dB, 5-Bit, TTL Driver, DC - 3.0 GHz Features Functional Schematic Attenuation: 0.5 dB steps to 15.5 dB Minimal Phase Variation over Attenuation Range Low DC Power Consumption Hermetic Surface Mount Package Integral TTL Driver 50 Ohm Nominal Impedance 260C Reflow Compatible RoHS* Compliant Description MACOMs MAAD-009195-000100 is a GaAs FET 5-bit digital attenuator with a 0.5 dB minimum step size and 15.5 dB total attenuation. The design has been optimized to minimize phase variation over the attenuation range. This attenuator and integral TTL driver is in a hermetically sealed ceramic 16-lead surface mount package. The MAAD-009195-000100 is ideally suited for use where accuracy, fast switching, very low power consumption and low 1 intermodulation products are required. Typical Pin Configuration applications include dynamic range setting in precision receiver circuits and other gain / leveling Pin No. Function Pin No. Function control circuits.
