POWER AMPLIFIER
The FreeStar Pro module incorporates a high performance Power Amplifier from NEC Electronics.
Power Amplifier Control Line
FreeStar Pro modules include a separate 1.8V regulator supplying a bias that enables consistent module output performance
over the wide operating range. To prevent excessive sleep current draw, this regulator should be disabled when the module is
placed into sleep mode.The voltage regulator is controlled by GPIO42 (ANT1), setting GPIO42 high enables the regulator while
setting GPIO42 low disables the regulator. See the table below for the Turn on Time requirements for the voltage regulator.
SPECIFICATIONS — GPIO42
For the TX_ON and RX_ON pins, the function table is as follows:
Other Notes:
RF Output Power Setting
In order to comply with FCC emissions requirements, the FreeStar PRO module must operate at reduced power settings
on channels 11 & 12. Channel 26 is unavailable. The firmware provided with the modules also limits the users to Test Tool
power step 2 for channels 11 & 12. This is to guarantee the module does not exceed 10dBm which is required to meet the
FCC requirements of this module.
In addition to restricting power, the firmware also limits the maximum data payload to 106 bytes for any transmitted packet.
This is to guarantee the module does not exceed 10dBm on channels 11 & 12 which is necessary to meet FCC emissions
requirements.
INTERFACE
The FreeStar Pro module has all major pins routed to the castellation connectors, this includes, but is not limited, to the pins for
JTAG, serial communication, A/D, etc.

• The GPIO43 (ANT2) pin is not used and is left unconnected.
• Due to the long turn on time (105µs) of the regulator, the regulator is enabled or ON all the time with the
• The RF switch uses both the TX_ON and RX_ON outputs as control inputs.
• The PA uses the TX_ON line as the control input.
