HMC424AG16 v00.0416 ATTENUATORS - DIGITAL - SMT 0.5dB LSB GaAs MMIC 6-BIT DIGITAL ATTENUATOR, DC - 3 GHz Typical Applications Features The HMC424AG16 is ideal for: 0.5 dB LSB Steps to 31.5 dB • Telecom Infrastructure Single Control Line Per Bit • Military Radios, Radar & ECM ±0.5 to ±0.8 dB Typical Bit Error • Space Applications 16 Lead Hermetic SMT Package • Test Instrumentation Functional Diagram General Description The HMC424AG16 is a broadband 6-bit GaAs IC digital attenuator in a 16 lead glass/metal (hermetic) surface mount package. Covering DC to 3 GHz, the insertion loss is less than 3 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ±0.5 dB typical step error with an IIP3 of +34 dBm. Six control voltage inputs, toggled between 0 and -5V, are used to select each attenuation state at less than 70 µA each. A single Vee bias of -5V allows operation at frequencies down to DC.
