HMC424ALH5 v00.0416 0.5dB LSB GaAs MMIC 6-BIT DIGITAL ATTENUATOR, DC - 13 GHz Typical Applications Features The HMC424ALH5 is ideal for: 0.5 dB LSB Steps to 31.5 dB Single Control Line Per Bit Telecom Infrastructure 0.3 dB Typical Bit Error Military Radio, Radar & ECM 2 Hermetic SMT Package, 25mm Space Systems Screening to MIL-PRF-38535 (Class B or S) Available Test Instrumentation Functional Diagram General Description The HMC424ALH5 is a broadband 6-bit GaAs MMIC digital attenuator housed in a hermetic SMT leadless package. Covering DC to 13 GHz, the insertion loss is less than 3.5 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. A single Vee bias of -5V allows operation at frequencies down to DC. The HMC424ALH5 is compatible with stan- dard and lead free surface mount manufacturing techniques and is suitable for high reliability military, industrial and space applications.
