Pi-Matching network needed when already 50Ohm matched on transceiver?

by MannFromTheMoon   Last Updated August 10, 2018 19:25 PM

I've been dreaming up a small gadget featuring a NRF51822 MCU as a centerpiece and I'm a total noob at RF-voodoo. I want to use a chip antenna. My question is this: Do i need this matching network From the Datasheet under reference design

From the MCU/Transceiver or this one From the Datasheet under reference design

From the chip-antenna datasheet or both?

I found some talk online of mixing the two together somehow but that was with a different configuration on the output of the MCU. Can someone help me or point me in the right direction?
