DNT2400 Antenna Connector
A U.FL miniature coaxial connector is provided on both DNT2400 configurations for connection to the RFIO port.
A short U.FL coaxial cable can be used to connect the RFIO port directly to an antenna. In this case the antenna
should be mounted firmly to avoid stressing the U.FL coaxial cable due to antenna mounting flexure. Alternately,
a U.FL coaxial jumper cable can be used to connect the DNT2400 module to a U.FL connector on the host circuit
board. The connection between the host circuit board U.FL connector and the antenna or antenna connector on
the host circuit board should be implemented as a 50 ohm stripline. Referring to Figure 3, the width of this stripline
depends on the thickness of the circuit board between the stripline and the groundplane. For FR-4 type circuit
board materials (dielectric constant of 4.7), the width of the stripline is equal to 1.75 times the thickness of the cir-
cuit board. Note that other circuit board traces should be spaced away from the stripline to prevent signal cou-
pling, as shown in Figure 4. The stripline trace should be kept short to minimize its insertion loss.
