13 / 212 page  CC2430 CC2430 Data Sheet (rev. 2.1) SWRS036F Page 13 of 211 7.2 RF Receive Section Measured on Texas Instruments CC2430 EM reference design with TA=25°C and VDD=3.0V unless stated otherwise. Table 6: RF Receive Parameters Parameter Min Typ Max Unit Condition/Note Receiver sensitivity -92 dBm PER = 1%, as specified by [1] Measured in 50 Ω single endedly through a balun. [1] requires –85 dBm Saturation (maximum input level) 10 dBm PER = 1%, as specified by [1] Measured in 50 Ω single endedly through a balun. [1] requires –20 dBm Adjacent channel rejection + 5 MHz channel spacing 41 dB Wanted signal -88dBm, 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 -88dBm, adjacent modulated channel at -5 MHz, PER = 1 %, as specified by [1]. [1] requires 0 dB Alternate channel rejection + 10 MHz channel spacing 55 dB Wanted signal -88dBm, 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 -88dBm, adjacent modulated channel at -10 MHz, PER = 1 %, as specified by [1] [1] requires 30 dB Channel rejection ≥ + 15 MHz ≤ - 15 MHz 55 53 dB dB Wanted signal @ -82 dBm. Undesired signal is an 802.15.4 modulated channel, stepped through all channels from 2405 to 2480 MHz. Signal level for PER = 1%. Values are estimated. Co-channel rejection -6 dB Wanted signal @ -82 dBm. Undesired signal is 802.15.4 modulated at the same frequency as the desired signal. Signal level for PER = 1%. Blocking / Desensitization + 5 MHz from band edge + 10 MHz from band edge + 20 MHz from band edge + 50 MHz from band edge - 5 MHz from band edge - 10 MHz from band edge - 20 MHz from band edge - 50 MHz from band edge -42 -45 -26 -22 -31 -36 -24 -25 dBm dBm dBm dBm dBm dBm dBm dBm Wanted signal 3 dB above the sensitivity level, CW jammer, PER = 1%. Measured according to EN 300 440 class 2. Spurious emission 30 – 1000 MHz 1 – 12.75 GHz −64 −75 dBm dBm Conducted measurement in a 50 Ω single ended load. Complies with EN 300 328, EN 300 440 class 2, FCC CFR47, Part 15 and ARIB STD-T-66. Frequency error tolerance ±140 ppm Difference between centre frequency of the received RF signal and local oscillator frequency. [1] requires minimum 80 ppm Symbol rate error tolerance ±900 ppm Difference between incoming symbol rate and the internally generated symbol rate [1] requires minimum 80 ppm 7.3 RF Transmit Section Measured on Texas Instruments CC2430 EM reference design with TA=25°C, VDD=3.0V, and nominal output power unless stated otherwise. |
