3.2.1 Certified Antennas

In all cases, assessment of the final product must be met against the Essential requirements of the Radio Equipment Directive Article 3.1(a) and (b), safety and EMC respectively, as well as any relevant Article 3.3 requirements. Refer to 4.3 for the official and complete CC1312PSIP Manual Information for the End User and OEM Installation Guide.

The antennas shown in Table 3-1 were verified in the conformity testing. A separate approval process is required for any other configurations. This is covered in Section 3.2.2.

The 4-layer design of LP-EM-CC1312PSIP [4.2] has an excellent efficiency and antenna gain. This is the recommended certified antenna for the CC1312PSIP [4.1] when there is space to implement a large PCB antenna design.

The external whip antenna is best for usage with a SMA connector. The chip antennas and wire antenna offer a more compact antenna design with a lower gain due to a smaller physical size. Antenna 0915AT43A0026 is used in the compact 2-layer design shown in Figure 3-5
