Unit Condition / Note Receiver Sensitivity -90 -95 dBm PER = 1%, as specified by [1] Measured in a 50 Ω single-ended load through a balun. [1] requires –85 dBm Saturation (maximum input level) 0 10 dBm PER = 1%, as specified by [1] Measured in a 50 Ω single–ended load through a balun. [1] requires –20 dBm Adjacent channel rejection + 5 MHz channel spacing 45 dB Wanted signal @ -82 dBm, adjacent modulated channel at +5 MHz, PER = 1 %, as specified by [1]. [1] requires 0 dB Adjacent channel rejection - 5 MHz channel spacing 30 dB Wanted signal @ -82 dBm, adjacent modulated channel at -5 MHz, PER = 1 %, as specified by [1]. [1] requires 0 dB Alternate channel rejection + 10 MHz channel spacing 54 dB Wanted signal @ -82 dBm, adjacent modulated channel at +10 MHz, PER = 1 %, as specified by [1] [1] requires 30 dB Alternate channel rejection - 10 MHz channel spacing 53 dB Wanted signal @ -82 dBm, adjacent modulated channel at -10 MHz, PER = 1 %, as specified by [1] [1] requires 30 dB Channel rejection ≥ + 15 MHz ≤ - 15 MHz 62 62 dB dB Wanted signal @ -82 dBm. Undesired signal is an IEEE 802.15.4 modulated channel, stepped through all channels from 2405 to 2480 MHz. Signal level for PER = 1%. Co-channel rejection -3 dB Wanted signal @ -82 dBm. Undesired signal is an IEEE 802.15.4 modulated at the same frequency as the desired signal. Signal level for PER = 1%. Blocking / Desensitisation +/- 5 MHz from band edge +/- 20 MHz from band edge +/- 30 MHz from band edge +/- 50 MHz from band edge -28 -28 -27 -28 dBm dBm dBm dBm Wanted signal 3 dB above the sensitivity level, CW jammer, PER = 1%. Complies with EN 300 440 class 2. Spurious emission 30 – 1000 MHz 1 – 12.75 GHz -73 -58 dBm dBm Conducted measurement in a 50 Ω single ended load. Measured according to EN 300 328, EN 300 440 class 2, FCC CFR47, Part 15 and ARIB STD-T-66 |
