Typical Applications
This HMC-VVD104 is ideal for:
• E-Band Communication Systems
• Short Haul / High Capacity Radios
• Automotive Radar
• Test Equipment
• SATCOM and Sensors
The HMC-VVD104 is a monolithic GaAs PIN diode
based Voltage Variable Attenuator (VVA) which
exhibits low insertion loss, high IP3, and wide dy-
namic range. The balanced topology delivers excellent
return loss while the single control voltage can be
applied to either side of the die. All bond pads and
the die backside are Ti/Au metallized, and the PIN
diode devices are fully passivated for reliable
operation. This wideband VVA MMIC is compatible
with conventional die attach methods, as well as
thermocompression and thermosonic wirebonding,
making it ideal for MCM and hybrid microcircuit
applications. All data shown herein is measured with
the chip in a 50 Ohm environment and contacted with
RF probes.
