6 / 92 page  CC1021 SWRS045 Page 6 of 91 4.1. RF Transmit Section Parameter Min Typ Max Unit Condition / Note Transmit data rate 0.45 153.6 kBaud The data rate is programmable. See section 10 on page 27 for details. NRZ or Manchester encoding can be used. 153.6 kBaud equals 153.6 kbps using NRZ coding and 76.8 kbps using Manchester coding. See section 9.2 on page 25 for details Minimum data rate for OOK is 2.4 kBaud Binary FSK frequency separation 0 0 108 216 kHz kHz in 402 - 470 MHz range in 804 - 940 MHz range 108/216 kHz is the maximum guaranteed separation at 1.84 MHz reference frequency. Larger separations can be achieved at higher reference frequencies. Output power 433 MHz 868 MHz -20 to +10 -20 to +5 dBm dBm Delivered to 50 Ω single-ended load. The output power is programmable and should not be programmed to exceed +10/+5 dBm at 433/868 MHz under any operating conditions. See section 14 on page 46 for details. Output power tolerance -4 +3 dB dB At maximum output power At 2.3 V, +85oC At 3.6 V, -40oC Harmonics, radiated CW 2nd harmonic, 433 MHz, +10 dBm 3rd harmonic, 433 MHz, +10 dBm 2nd harmonic, 868 MHz, +5 dBm 3rd harmonic, 868 MHz, +5 dBm -50 -50 -50 -50 dBc dBc dBc dBc Harmonics are measured as EIRP values according to EN 300 220. The antenna (SMAFF-433 and SMAFF-868 from R.W. Badland) plays a part in attenuating the harmonics. Adjacent channel power (GFSK) 433 MHz 868 MHz -46 -42 dBc dBc ACP is measured in a 100 kHz bandwidth at ±100 kHz offset. Modulation: 19.2 kBaud NRZ PN9 sequence, ±19.8 kHz frequency deviation. Occupied bandwidth (99.5%,GFSK) 433 MHz 868 MHz 60 60 kHz kHz Bandwidth for 99.5% of total average power. Modulation: 19.2 kBaud NRZ PN9 sequence, ±19.8 kHz frequency deviation. Modulation bandwidth, 868 MHz 19.2 kBaud, ±9.9 kHz frequency deviation 38.4 kBaud, ±19.8 kHz frequency deviation 48 106 kHz kHz Bandwidth where the power envelope of modulation equals ñ36 dBm. Spectrum analyzer RBW = 1 kHz. |
