The MeshConnect Sub-G modules are based on the Silicon Labs Si1000 and Si1002 wireless SoCs ICs. These devices
incorporate the RF transceiver with the baseband modem, a hardwired MAC, and an embedded 8051 microcontroller,
offering a high performance solution for all Sub-G applications.

ANTENNA
The MeshConnect Sub-G modules include RF connectors for external antenna options only (There is no trace antenna
option). The following options are supported by CEL:
•
U.FL connector to support cabled antenna
•
RP-SMA connector
•
1/4 wave wire antenna in place of RP-SMA
Here are some design guidelines to help ensure antenna performance:
•
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.
•
Antenna performance may be improved if module is mounted on carrier board with large ground plane
(3 in x 3in) provided clearance is allowed for center pin of RPSMA or Wire
ADDITIONAL FLASH MEMORY (Optional)
The Silicon Labs Transceiver ICs (Si1000 and Si1002) have an embedded 64kB of flash. Additional Flash memory (1MB)
can be mounted on each module (as an option) to enable Over The Air (OTA) programming capability.
This option is available for all part numbers, but must be specified at the time of ordering.
