General Description
The HMC-C018 is a DC to 13 GHz 6-bit GaAs IC
Digital Serial Control Attenuator housed in a miniature
hermetic module. This wideband attenuator features
3.6 dB typical 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. A six
bit CMOS compatible serial control word is used to
select each attenuation state and 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.
Electrical Specifications, TA = +25° C, With VDC = -5V and 0/+5V CMOS Control
