9 / 152 page  CC1010 SWRS047 Page 9 of 152 8. RF transmit section Parameter Min. Typ. Max. Unit Condition Binary FSK frequency separation 0 64 65 kHz The frequency corresponding to the digital "0" is denoted f0, while f1 corresponds to a digital "1". The frequency separation is f1-f0. The RF carrier frequency, fc, is then given by fc=(f0+f1)/2. (The frequency deviation is given by fd=+/-(f1-f0)/2 ) The frequency separation is programmable in 250 Hz steps. Separations up to 65 kHz are guaranteed at 1 MHz reference frequency. Larger separations can be achieved at higher reference frequencies Output power 433 / 868 MHz -20 0 10/4 dBm Delivered to single-ended 50 Ω load. The output power is programmable, see page 123 RF output impedance 433 / 868 MHz 140/80 Ω Transmit mode, optimum load impedance. For matching details see “Input/ output matching” p.120 Harmonics 2 nd harmonic, 433 / 868 MHz 3 rd harmonic, 433 / 868 MHz -7/-15 -27/-29 dBm Conducted measur at maximum output power. An external LC filter should be used to reduce harmonics emission to comply with SRD requirements. See p.128 Table 7. RF transmit characteristics |
