HMC-C018
0.5dB LSB GaAs MMIC 6-BIT DIGITAL
SERIAL CONTROL ATTENUATOR MODULE, DC - 13 GHz
v03.0310
Functional Diagram
Electrical Specifications, T
A = +25 °C, with Vdc = -5V and 0/+5V CMOS Control
the HMC-C018 is ideal for:
telecom Infrastructure
Military radio, radar & eCM
space systems
test Instrumentation
0.5 dB LsB steps to 31.5 dB
CMos Compatible serial Data Interface
typical Bit error: ±0.3 dB
Hermetically sealed Module
Field replaceable sMA Connectors
-55 °C to +85 °C operating temperature
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.
