Complies Spurious emissions with EN 300 328, EN 300 440 class 2, FCC CFR47, Part 15 and ARIB –41 dBm STD-T-66(1) TX mode, –23-dBm output power, no peripherals active, low MCU 21.1 activity, MCU at 250 kHz TX mode, –6-dBm output power, no peripherals active, low MCU 23.8 activity, MCU at 250 kHz Current consumption mA TX mode, 0-dBm output power, no peripherals active, low MCU 27 activity, MCU at 250 kHz TX mode, 4-dBm output power, no peripherals active, low MCU 31.6 activity, MCU at 250 kHz Differential impedance as seen from the RF port (RF_P and RF_N) Optimum load impedance 70 + j30 Ω toward the antenna (1) Designs with antenna connectors that require conducted ETSI compliance at 64 MHz should insert an LC resonator in front of the antenna connector. Use a 1.6-nH inductor in parallel with a 1.8-pF capacitor. Connect both from the signal trace to a good RF ground.
