ATTENUATORS - DIGITAL - SMT v04.0709 5 Typical Applications The HMC424G16 is ideal for: Telecom Infrastructure Military Radios, Radar & ECM Space Applications Test Instrumentation Functional Diagram HMC424G16 0.5dB LSB GaAs MMIC 6-BIT DIGITAL ATTENUATOR, DC - 3 GHz Features 0.5 dB LSB Steps to 31.5 dB Single Control Line Per Bit ±0.5 to ±0.8 dB Typical Bit Error 16 Lead Hermetic SMT Package General Description The HMC424G16 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 +32 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.
