AT-210

Digital Attenuator, 15 dB, 4-Bit DC-2.0 GHz Features • • • • • • • Attenuation 1-dB Steps to 15 dB High Accuracy Low Intermodulation Product: +50 dBm IP3 Low DC Power Consumption: 50 µW SOIC-16 Plastic Package Tape and Reel Packaging Available Temperature Stability +/-0.15 dB: -40°C to +85°C AT-210 V4 Functional Schematic Description M/A-COM’s AT-210 is a 4-bit, 1-dB step GaAs MMIC digital attenuator in a low cost SOIC 16-lead surface mount plastic package. The AT-210 is ideally suited for use where high accuracy, fast switching, very low power consumption and low intermodulation products are required. Typical applications include radio, cellular, and wireless LANs, GPS equipment and other Gain/Level Control circuits. The AT-210 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
