The CHA6558-99F is a monolithic four
stages GaAs high power amplifier, designed
for Ka-Band applications.
The circuit is dedicated to telecommunication
and VSAT, SATCOM and is also well suited
for a wide range of microwave applications
and systems.
It is developed on a robust 0.15µm gate
length pHEMT process, via holes through the
substrate, air bridges and electron beam
gate lithography.
It is available in chip form.

Recommended Chip assembly & Bonding Diagram
-For best thermal and electrical performances, the chip should be brazed on a metal base
plate.
The RF and DC connections should be done according to the following table:
- DC drain voltage (Pads: D*): Connection of all the pads is mandatory excepted Pad D2
which can be used on one side only. (Pin number 5 or 19)
-DC gate voltage: (Pads G*): Connection of all the pads is mandatory excepted Pads G2 &
G3 (Pin number 4 or 20 for G2 & Pin number 7 or 17 for G3) which can be used on one side
only.
Note: Connection of the pin 19 (other possibility to connect D2) is not mandatory if
connection of pin 5 has been used, nevertheless it is necessary to add the 120pF and 10nF
external capacitor.

ESD protections exist on RF accesses. Note that supply feed should be bypassed.
ESD protections are also implemented on each gate access.
It is mandatory to provide a good external DC decoupling on the PC board, as close as
possible to the chip.
