Functional Diagram
General Description
The HMC-VVD104 is a monolithic GaAs PIN diode
based Voltage Variable Attenuator (VVA) which
exhibits low insertion loss, high IP3, and wide dynamic
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.
