Application Note: Budgeting Harmonics For ZigBee Front-End Modules
The growth of low-power, cost-effective wireless radio systems is driving more applications to use the ZigBee communication standard. Some of these applications require a signal to propagate over a short range. When installed in a large building or operating outdoors over a wide area, such a system may benefit from transmitting more power. This article details how to specify harmonics for a ZigBee Front-End Module (FEM). Requirements from the different regulatory standards are reviewed and analyzed using the simulation harmonic content of Offset Quadrature Phase-Shift Keying (OQPSK) spread spectrum modulation. The effects of the measurement bandwidth and detector on the harmonics level of both sine and ZigBee waveforms are also evaluated.
