  • Page 5 External IF filter The evaluation board is equipped with an external 455kHz ceramic filter. Input and output impedance to the CC400 is 1.5kΩ, and the bandwidth is approximately 30kHz. CC400DK Development kit (rev. 1.5) 2002-09-17 Page 5 of 22...
  • Page 6 Minor tuning of the component values may be necessary to compensate for layout parasitics at other frequencies or other layouts. See appendix A. CC400DK Development kit (rev. 1.5) 2002-09-17 Page 6 of 22...
  • Page 7 There are three preselector filter options: LC-filter, SAW filter, or no filter used. Each of the three filter alternatives is equipped with a female SMA antenna connector. To choose between the three filters there is a zero ohm resistor that can be moved (R61-R63). CC400DK Development kit (rev. 1.5) 2002-09-17 Page 7 of 22...
  • Page 8 Note: Using the SAW filter, the output power amplifier class should be A or AB and the output power should not exceed 0 dBm. This will give approximately –5 dBm at the antenna output. Using power settings above 0 dBm may cause stability problems. CC400DK Development kit (rev. 1.5) 2002-09-17 Page 8 of 22...
