5.8- 8.5GHz Power Amplifier
CHA6552-QJG
Notes
Due to ESD protection circuits on RF input, an external capacitance might be requested to
isolate the product from the external voltage that could be present on the RF access.

The DC connections do not include any decoupling capacitor in package, therefore it is
mandatory to provide a good external DC decoupling (100pF, 10nF, 1µF) on the PC board,
as close as possible to the package.
A 10KΩ resistor is recommended in parallel to VDET, and VREF accesses.
Please note that it is not mandatory to use both detectors, on north and south sides.
If only one detector is used, the unused pads VDET, VREF and VDC could be unconnected
or grounded.
