Preliminary Information
LPCC 6 PCB Footprint Layout
Applications Information
For test and design purposes, SiGe Semiconductor offers an evaluation board for the PA2423L. The order
part number for the evaluation board is PA2423L-EV. The evaluation board is intended to simplify the
testing with respect to RF performance of this power amplifier.
The application note, 05AN006 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.
Using V
RAMP
V
is a digital pin used to power-up and power-down the PA2423L in Time Duplex systems such as
RAMP
tm
1.1. During receive mode, V
voltage is pulled down, PA2423L acts as a 25 dB isolation block
Bluetooth
RAMP
between the radio and the antenna while consuming a modest 1uA. In transmit mode, V
voltage is
RAMP
pulled to VCC and PA2423L offers 19 dB to 21dB of large signal gain. The rise and fall time are in the order
of 1-2usec.
