PA2423MB
2.4 GHz Bluetooth Class 1 Power Amplifier IC
Production Information
MSOP 8 PCB Footprint Layout
Applications Information
For test and design purposes, SiGe Semiconductor offers an evaluation board for the PA2423MB. The
order part number is PA2423MB-EV. The evaluation board is intended to simplify the testing with respect to
RF performance of this power amplifier.
The application note, 05AN005 provides the supporting information for using the evaluation board. It
contains information on the schematic, bill of materials and recommended layout for the power amplifier and
the input and output matching networks. To assist in the design process, this layout is available, upon
request, in gerber file format.
In addition, a new optimized layout is available which reduces the number of components used. It achieves
this reduction by using printed inductors on the PCB. This layout is available as a gerber file to aid in a
quick design cycle. The application note, 05AN008, provides information on this space optimized layout.

pulled to VCC and PA2423MB offers 19 dB to 21dB of large signal gain. The rise and fall time are in the
order of 1-2usec.
