General Description
The HMC424LH5 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 +32 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
HMC424LH5 is compatible with standard and lead free
surface mount manufacturing techniques and is suit-
able for high reliability military, industrial and space
applications.

Suggested Driver Circuit (One Circuit Required Per Bit Control Input)
Simple driver using inexpensive standard logic ICs provides fast
switching using minimum DC current.
* Recommended value to suppress unwanted RF signals at V1
- V6 control lines.
