General Description
The HMC677LP5(E) is a multi-function BiCMOS
control interface IC which is ideal for driving the gates
of FET and pHEMT based MMIC control devices.
This unique IC can be used to simplify the control
of microwave and millimeterwave transmit/receive
modules, military subsystems, and multi-throw/
multi-port test and measurement equipment. The
HMC677LP5(E) accepts serial or parallel data, and
can drive up to 6 complementary sets of outputs.
The HMC677LP5(E) also provides additional
functionality such as a power-up state selection,
adjustable output voltage levels, and a latched paral-
lel control mode which allows multiple control devices
to share a common data bus. The HMC677LP5(E)
is ideal for controlling digital phase shifters, digital
attenuators, digital variable gain amplifiers, and
switching matrices embedded in complex microwave
and millimeterwave assemblies.
