MAAD-009194

MAAD-009194 Constant Phase Digital Attenuator 31.0 dB, 5-Bit, TTL Driver, DC-3.0 GHz Features  Attenuation: 1 dB steps to 31 dB  Minimal Phase Variation over Attenuation Range  Low DC Power Consumption  Hermetic Surface Mount Package  Integral TTL Driver  50 Ω Nominal Impedance  RoHS* Compliant and 260°C Reflow Compatible Description The MAAD-009194-000100 is a GaAs FET 5-bit digital attenuator with a 1 dB minimum step size and 31 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-009194-000100 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. Environmental screening is available. Contact the factory for information.
