EV1HMC424ALH5

EV1HMC424ALH5 is a HMC424ALH5 evaluation board. The HMC424ALH5 is a broadband 6-bit GaAs MMIC digital attenuator housed in a hermetic SMT leadless package. Covering DC to 13GHz, the insertion loss is less than 3.5dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16dB for a total attenuation of 31dB. Attenuation accuracy is excellent at ±0.5dB typical step error with an IIP3 of +34dBm. 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 standard and lead free surface mount manufacturing techniques and is suitable for high reliability military, industrial and space applications.
