  1. Dual Band Reference Design Results SHE February 2013

  2. Dual Band CC112x/CC12xx RX Balun Filter Band 1 50Ohm I/O RF SPDT switch Filter Band 2 TX Balun

  3. 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

  4. Measurement Results • Above is without filter or switch • Filters needed to attenuate harmonics • Has a finite insertion loss • Switch needed • Has a finite insertion loss
