MeshConnect? Module Series
ANTENNA
CEL's MeshConnect modules include an integrated Printed Circuit Board (PCB) trace antenna. An optional u.FL connector
can be specified, providing connection to a 50-ohm external antenna of the user’s choice. See Ordering Information on
page 1.
The PCB antenna employs an F-Antenna topology that is compact and supports an omni-directional radiation pattern.
To maximize antenna efficiency, an adequate ground plane must be provided on the host PCB. Correctly positioned, the
ground plane on the host PCB will contribute significantly to the antenna performance (it should not be directly under
the F-Antenna). The position of the module on the host board and overall design of the product enclosure contribute to
antenna perfor mance. Poor design affects radiation patterns and can result in reflection, diffraction, and/or scattering of the
transmitted signal.
Here are some design guidelines to help ensure antenna performance:
? Never place the ground plane or route copper traces directly underneath the antenna portion of the module.
? Never place the antenna close to metallic objects.
? In the overall design, ensure that wiring and other components are not placed near the antenna.
? Do not place the antenna in a metallic or metalized plastic enclosure.
? Keep plastic enclosures 1cm or more from the antenna in any direction.
For optimum antenna performance, the MeshConnect modules should be mounted with the PCB trace antenna
overhanging the edge of the host board. To further improve performance, a ground plane may be placed on the host board
under the module, up to the antenna. The installation of an uninterrupted ground plane on a layer directly beneath the
module will also allow you to run traces under this layer. CEL can provide assistance with your PCB layout.
MODES OF OPERATION
There are three power down modes in the IC. Each mode can be set using the PDMODE [1:0] bits in the PDCON register
and power down modes can be started by setting the PDSTART bit to 1. Each mode has a different current consumption
and wake-up sources, please refer to the IC datasheet for further information on the available power down modes. Table 8
describes the three power down modes.
