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.
