Space Systems
Test Instrumentation
0.5 dB LSB Steps to 31.5 dB
Single Control Line Per Bit
± 0.3 dB Typical Bit Error
Hermetic SMT Package, 25mm2
Screening to MIL-PRF-38535 (Class B or S) Available
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 suitable for high reliability military, industrial
and space applications.
