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 typi-
cal 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 attenu-
ation state. A single Vdc bias of -5V allows operation
at frequencies down to DC. Removable SMA connec-
tors can be detached to allow direct connection of the
module’s I/O pins to a microstrip or coplanar circuit.
Electrical Specifications, TA = +25° C, With Vdc = -5V & VCTL = 0/+5V
