| MAAD-009170-000100 Digital Attenuator, Constant Phase 15.5 dB, 5-Bit, TTL Driver, DC-4.0 GHz Features * * * * * * * * Attenuation: 0.5 dB Steps to 15.5 dB Minimal Phase Variation over Attenuation Range Low DC Power Consumption Small Footprint, PQFN Package Integral TTL Driver 50 ohm Impedance Test Boards are Available RoHS* Compliant Rev. V1 Functional Schematic Description M/A-COM's MAAD-009170-000100 is a GaAs pHEMT 5-bit digital attenuator with integral TTL driver in an PQFN plastic surface mount package. Step size is 0.5 dB providing a 15.5 dB total attenuation range. This design has been optimized to minimize phase variation over the attenuation range. MAAD-009170-000100 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.
