GaAs MMIC VOLTAGE-VARIABLE
ATTENUATOR, DC - 20 GHz
External op-amp control circuit maintains
impedance match while attenuation is varied.
Input control ranges from 0 Volts (min.
attenuation) to -3.0 Volts (max. attenuation.)

Mounting & Bonding Techniques for Millimeterwave GaAs MMICs
The die should be attached directly to the ground plane eutectically or with conductive epoxy (see HMC general Handling,
Mounting, Bonding Note).
50 Ohm Microstrip transmission lines on 0.127mm (5 mil) thick alumina thin film substrates are recommended for bringing
RF to and from the chip (Figure 1). If 0.254mm (10 mil) thick alumina thin film substrates must be used, the die should be
raised 0.150mm (6 mils) so that the surface of the die is coplanar with the surface of the substrate. One way to accomplish
this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then
attached to the ground plane (Figure 2).
Microstrip substrates should brought as close to the die as possible in order to minimize bond wire length. Typical die-to-
substrate spacing is 0.076mm to 0.152 mm (3 to 6 mils).
