What are "radio frequency legs" (or did I mix up my TLAs again?)

One of many ARINC-specified RNAV legs; radius-to-fix. A curved flight
path much, much more precise than an AF (arc-to-fix) leg used to overlay
a DME arc.

Palm Springs RNAV (RNP) Runway 13R is an application of RF legs. In the
not too distant future RF legs will be used for basic RNAV to get to
runway ends not posible with straight (TF, or track-to-fix) legs.
