Application note
SPIRIT1: increasing the output power
By Giuseppe Cantone
Introduction
The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in
the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD
frequency bands at 169, 315, 433, 868 and 915 MHz.
This application note reports the modifications in the PCB schematic and in the SPIRIT1
configuration to increase the output power in transmission mode, the maximum output
power achievable and the related current consumption measurements in the ISM frequency
bands.
