Data Sheet
FEATURES
GENERAL DESCRIPTION
1.0 dB LSB steps to 31 dB
Single positive control line per bit
1.0 dB typical bit error
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.
Input IP3: 43 dBm
CMOS-compatible control
Hermetically sealed module
Field replaceable K-type connectors
Operating temperature: −55°C to +85°C
APPLICATIONS
Fiber optics and broadband telecommunications
Microwave radios and VSATs
Military radios, radars, and electronic counter measures (ECM)
Space systems
Test instrumentation
