| MAAD-009260-000100 Constant Phase Digital Attenuator 32 dB, 2-Bit, TTL Driver, DC-3.0 GHz Features * * * * * * * * Attenuation: Two 16 dB bits 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 Rev. V1 Functional Schematic Description M/A-COM's MAAD-009260-000100 is a GaAs FET 2-bit digital attenuator with two 16 dB steps and 32 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-009260-000100 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.

Handling Procedures Please observe the following precautions to avoid damage: Truth Table (Digital Attenuator) 8 C2 0 0 1 C1 0 1 1 Attenuation Loss, Reference 16.0 dB 32.0 dB Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. 0 = TTL Low; 1 = TTL High 8. C1 is specified as the control for the 16 dB bit. We show data for the performance with the C2 control - note that the power handling is reduced if C2 is used for the 16 dB bit. The electrical performance of the 16 dB bit controlled by C2 is not specified. 3 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions * North America Tel: 800.366.2266 * Europe Tel: +353.21.244.6400 is considering for development.
