  • Page 37: Antenna

    7.1.1. GE866-QUAD Antenna – PCB line Guidelines When using the Telit GE866-QUAD module, since there's no antenna connector on the module, the antenna must be connected to the GE866-QUAD through the PCB with the antenna pad (pin G2). WARNING: High Frequency harmonics may still not be sufficiently attenuated in the GE866’s small package.
  • Page 38 In the case that the antenna is not directly developed on the same PCB, hence directly connected at the antenna pad of the GE866-QUAD, then a PCB line is needed in order to connect with it or with its connector.

  • Page 39: Pcb Design Guidelines

    7.2.1. Transmission line design During the design of the GE866-QUAD interface board, the placement of components has been chosen properly, in order to keep the line length as short as possible, thus leading to lowest power losses possible. A Grounded Coplanar Waveguide (G-CPW) line has been chosen, since this kind of transmission line ensures good impedance control and can be implemented in an outer PCB layer as needed in this case.

  • Page 40: Transmission Line Measurements

    Transmission line measurements HP8753E VNA (Full-2-port calibration) has been used in this measurement session.
