8 / 91 page  Not Recommended for New Designs NRND CC1021 SWRS045D – JANUARY 2006 – REVISED JANUARY 2015 www.ti.com RF Transmit (continued) All measurements were performed using the two-layer PCB CC1020EMX reference design. See Figure 6-1. The electrical specifications given for 868 MHz are also applicable for 902 to 928 MHz. TA = 25°C, AVDD = DVDD = 3.0 V, fC = 14.7456 MHz if nothing else stated. PARAMETER MIN TYP MAX UNIT CONDITION 433 MHz –20 to +10 dBm Delivered to 50 Ω single-ended load. The output power is programmable and should not be programmed to Output power exceed +10/+5 dBm at 433/868 MHz 868 MHz –20 to +5 dBm under any operating conditions. See Section 5.11 for details. At 2.3 V, +85°C –4 dB Output power At maximum output power tolerance At 3.6 V, –40°C 3 dB 2nd harmonic, 433 MHz, –50 dBc +10 dBm Harmonics are measured as EIRP 3rd harmonic, 433 MHz, –50 dBc values according to EN 300 220. The +10 dBm Harmonics, antenna (SMAFF-433 and SMAFF- radiated CW 2nd harmonic, 868 MHz, 868 from R.W. Badland) plays a part –50 dBc +5 dBm in attenuating the harmonics. 3rd harmonic, 868 MHz, –50 dBc +5 dBm 433 MHz –46 dBc ACP is measured in a 100 kHz bandwidth at ±100 kHz offset. Adjacent channel Modulation: 19.2 kBaud NRZ PN9 power (GFSK) 868 MHz –42 dBc sequence, ±19.8 kHz frequency deviation. 433 MHz 60 kHz Bandwidth for 99.5% of total average Occupied power. bandwidth Modulation: 19.2 kBaud NRZ PN9 868 MHz 60 kHz (99.5%,GFSK) sequence, ±19.8 kHz frequency deviation. 19.2 kBaud, ±9.9 kHz Bandwidth where the power 48 kHz Modulation frequency deviation envelope of modulation equals bandwidth, –36 dBm. Spectrum analyzer 38.4 kBaud, ±19.8 kHz 868 MHz 106 kHz RBW = 1 kHz. frequency deviation 47 to 74 MHz, At maximum output power, 87.5 to 118 MHz, +10/+5 dBm at 433/868 MHz. –54 dBm 174 to 230 MHz, To comply with EN 300 220, FCC 470 to 862 MHz CFR47 part 15 and ARIB STD-T96 an external (antenna) filter, as 9 kHz to 1 GHz –36 dBm implemented in the application circuit in Figure 5-22, must be used and tailored to each individual design to reduce out-of-band spurious emission levels. Spurious emissions can be measured as EIRP values according to EN 300 220. The antenna Spurious emission, (SMAFF-433 and SMAFF-868 from radiated CW R.W. Badland) plays a part in attenuating the spurious emissions. If the output power is increased using 1 to 4 GHz –30 dBm an external PA, a filter must be used to attenuate spurs below 862 MHz when operating in the 868 MHz frequency band in Europe. Application Note Application Note AN036 CC1020/1021 Reducing Spurious Emission (SWRA057) presents and discusses a solution that reduces the TX mode spurious emission close to 862 MHz by increasing the REF_DIV from 1 to 7. 8 Specifications Copyright © 2006–2015, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: CC1021 |
