GENERAL DESCRIPTION
The HMC-C584 is a 0.1 GHz to 40 GHz, 5-bit, gallium arsenide
(GaAs) IC digital attenuator housed in a miniature hermetic
module. This wideband attenuator features 7 dB typical insertion
loss, 43 dBm input IP3, and bit values of 1 dB (LSB), 2 dB, 4 dB,
8 dB, and 16 dB for a total attenuation range of 31 dB. The
attenuation accuracy of the device has a ±1.0 dB typical step error.
Five control voltage inputs, toggled between 0 V and 5 V, are used
to select each attenuation state. Removable K-type connectors
can be detached to allow direct connection of the input/output
pins of the module to a microstrip or coplanar circuit.

THEORY OF OPERATION
Any combination of the states listed in Table 4 provides an
attenuation level approximately equal to the sum of the bits
selected from 0 dB to 31 dB.
A low state level is a voltage between 0 V and 1.5 V. A high state
level is a voltage between 3.5 V and 5.0 V.

APPLICATIONS INFORMATION
In Figure 9, the HMC-C584 is used to make a variable gain
amplifier. In this application circuit, the HMC-C584 is used to
vary the amplitude of the signal feeding the amplifier over a
31 dB dynamic range. This type of circuit can be used to adjust
the overall gain for temperature or frequency. This is only one
of the many applications of the HMC-C584.
