Biasing
Circuit
This device is manufactured using a GaInP
HBT process, including, via holes through the
substrate and air bridge. A nitride layer protects
the transistors and the passive components.

Bonding recommendations
For thermal and electrical considerations, the chip should be brazed on a metal base plate.
The RF, DC and modulation port inter-connections should be done according to the following
table:
Port
Connection
IN (1)
Inductance (Lbonding) = 0.3nH
400µm length with wire diameter of 25 µm
OUT (12)
Inductance (Lbonding) = 0.3nH
400µm length with wire diameter of 25 µm
DC pads to 1st decoupling level
for double bonding
DC pads to 1st decoupling level
for single bonding
Inductance (Lbonding) =0.7nH
Two 1.2mm length wires with a diameter of 25 µm
Inductance (Lbonding) =1nH
One 1.2mm length wires with a diameter of 25 µm
1st decoupling level to 2nd
decoupling level for double
bonding
Inductance (Lbonding) =0.7nH
Two 1.2mm length wires with a diameter of 25 µm
1st decoupling level to 2nd
decoupling level for single
bonding
