General Description
The HMC-C025 is a DC to 13 GHz 6-bit GaAs IC
Digital Attenuator housed in a miniature hermetic
module. This wideband attenuator features 4 dB ty-
pical insertion loss, +38 dBm input IP3, and bit values
of 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation
of 31.5 dB. Attenuation accuracy is excellent with
±0.3 dB typical step error. Six control voltage inputs,
toggled between 0 and +5V, are used to select each
attenuation state. A single Vdc bias of -5V allows
operation at frequencies down to DC. Removable
SMA connectors can be detached to allow direct
connection of the module’s I/O pins to a microstrip or
coplanar circuit.
