HMC424AG16 v00.0416 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 bet- ween 0 and -5V, are used to select each attenuation state at less than 70 A each. A single Vee bias of -5V allows operation at frequencies down to DC. Electrical Specifications, T = +25 C, With Vee = -5V & Vctl = 0/-5V A Parameter Frequency (GHz) Min. Typ. Max.
