Dual Band Reference Design Results SHE February 2013
TI Confidential – NDA Restrictions Dual Band CC112x/CC12xx RX Balun TX Balun 50Ohm I/O RF SPDT switch Filter Band 1 Filter Band 2
TI Confidential – NDA Restrictions BOM TX path uses 868 MHz BOM RX path uses 433 MHz BOM Exception is C181 which is 3.9 pF No filtering between switch and antenna in the measurements –Must be added to final design
TI Confidential – NDA Restrictions Measurement Results 433 [MHz]868 [MHz]ETSI limit Output Power [dBm] / +14 dBm 2nd harmonic [dBm] / -30 dBm 3rd harmonic [dBm] / -30 dBm TX current [mA] Sensitivity [dBm] Above is without filter or switch Filters needed to attenuate harmonics –Has a finite insertion loss Switch needed –Has a finite insertion loss
