Introduction This application note describes a method which could be used to characterize adjacent channel rejection (ACR chips. It also compares different methods used by other manufacturers when quoting ACR performance. Adjacent channel rejection (ACR ...

Interferer waveforms Table 1. Minimum receiver jamming resistance requirements for 2450 MHz PHY Adjacent channel rejection The adjacent channel rejection shall be measured as follows. The desired signal shall be a compliant 2450MHz IEEE 802.15.4 signal of pseudo-random data. The ...

AN3218 Figure 1. Comparison of spectra, 25 MHz span It can be seen that the heavily filtered 15.4 signal generated by the signal generator is not representative of either type of modulation technique, and therefore does not give a useful ...

Co-channel measurements Figure 2. Comparison of spectra, 10 MHz span 4 Co-channel measurements It should also be noted that co-channel interference measurements should be made using a properly modulated IEEE 802.15.4-2003 signal, and not with an MSK signal with random ...
