3.1.1 RF path with matching components
RF matching needs to be adjusted to be able to reach sensitivity performances on the FRDM-KW36 board Rev B and Rev B1.
Original component values are L2 = 5.1 nH & C50=0.7 pF.
Measurements are done using the SMA connector. Therefore, the C57 capacitor is mounted and the C55 capacitor is not
mounted.
Figure 7. Matching components
Matching components must be: L2 = 4.7 nH & C50 = 0.6 pF. The following tables show the tested components to achieve proper
sensitivity performance.
• L2 = 4.7 nH
Description Mfr. name Mfr. part number
IND -- 0.0047 mH @ 500 MHz 300 mA
+/-0.1 nH 0402 MURATA LQP15MN4N7B02
• C50 = 0. 6 pF
Description Mfr. name Mfr. part number
CAP CER 0.6 pF 50 V 0.1 pF C0G 0402 MURATA GRM1555C1HR60BA01D
3.1.1.1 Current hardware: FRDM-KW36 Rev. B & B1 results
Figure 8 and Figure 9 show the results when using L2 = 5.1 nH & C50 = 0.7 pF.
