13 Layout Guidelines
13.1 WT21-N
RF output can be taken directly from the RF test point (RFTP) of the module. RFTP has a signal
pin surrounded by a ground. Dimensions for the RFTP are shown in the figure below. Use 50
ohm trace to route RF from RFTP. With WT21-A leave RFTP floating and do not place copper
directly under RFTP.
