UMS CHK025A-SOA

CHK025A-SOA
25W Power Packaged Transistor
GaN HEMT on SiC
Description
The CHK025A-SOA is an unmatched
packaged Gallium Nitride High Electron
Mobility Transistor. It offers general purpose
and broadband solutions for a variety of RF
power applications. It is well suited for multipurpose applications such as radar and
telecommunication.
The CHK025A-SOA is developed on a 0.5µm
gate length GaN HEMT process. It requires
an external matching circuitry.
The CHK025A-SOA is available as a
ceramic-metal
flange
power
package
providing low parasitic and low thermal
resistance.

Input RF and gate voltage are pulsed. Conditions are 25µs width, 10% duty cycle and
1µs offset between RF and DC pulse.
These values are the intrinsic performance of the packaged device. They are deduced from
measurements and simulations. They are considered in the reference plane defined by the
leads of the package, at the connection interface with the PCB.
The typical performance achievable in more than 20% frequency band around 4GHz was
demonstrated using the reference board 61500252 presented hereafter.

25W Power Packaged Transistor
Recommended Assembly Procedure
CHK025A-SOA is available has a flange package to be bolt down onto a thermal heat sink
also used as main electrical ground. Use preferably screw M2 and flat washers.
Thermal and electrical resistance at the package to heat sink interface has to be as low as
possible. Thermal electrically conductive grease or conductive thin layer like indium sheets
are recommended between the package and the heat sink.
In case a thermal grease is selected, we recommend to use material offering thermal
conductivity >5W/m.K and electrical resistivity <0.01 ohm.cm. The grease layer thickness
should be about 25µm (1 mil).
Contact interface quality can be improved by cleaning process prior device mounting on the
heat-sink. Such operation will enhance the thermal and electrical contact by oxides removal
at each interface.
Package leads can be soldered on printed circuit board’s traces by using RoHS solder past.
Cavity depth and width to be performed into the heat-sink where the device will be mounted
are important to achieve the best performances. These dimensions have to be optimized in
order to minimize the distance between device and signal traces made on the printed circuit
board (PCB). But they also have to be calculated in order to accommodate device variations
in height. The following drawing gives the relationship between device dimensions (Hpack &
Wpack) and optimal cavity depth (Hcav) and width (Wcav) depending on the printed circuitboard configuration (HPCB)
