Chip antenna circuit components



  • In both OEM L01 and universal reference board designs, the value of L17 is noted as a "2.7pF" capacitance:

    Looking at the pick & place file for the L01 board, it appears L17 is actually an LQW15AN6N2B00D 6.2 nH inductor. The same file also lists L16 as actually being LQW15AN8N2G00D, which is 8.2 nH, and C16 as being 0.8 pF

    The antenna's (2450AT43B100) datasheet meanwhile suggests using 2.7 nH and 1.8 nH inductors with their evaluation board.

    I'd like to confirm the actual nature and values used in the Pycom devkit boards?
