switching ICs, take care of shielding them with a metal frame cover.

 If EM noisy devices are not present around the line use of geometries like Micro strip

or Grounded Coplanar Waveguide are preferred since they typically ensure less

attenuation when compared to a Strip line having same length.

6.3. CDMA Antenna installation Guidelines

 Install the antenna in a place covered by the CDMA signal.

 If the device antenna in the application is located greater then 20cm from the human

body and there are no co-located transmitters then the Telit FCC/IC approvals can be

re-used by the end product.

 Antenna shall not be installed inside metal cases.

 Antenna shall be installed also according to antenna manufacture instructions.

WARNING:

Consider a mechanical design and a low-capacitance ESD protection device to protect

CE910-DUAL or customer specific requirements from ESD event to Antenna port (K1).
