To protect sensitive RF signals from electromagnetic interference and also from generating and radiating interference, the Dual Channel RF Module is designed on a multilayer PWB with embedded RF Strip-line topology.

The cards are the maximum allowable height to fit in the 2U chassis shown, and reside in a custom card cage ,supported by resident power supply and controller.

A complete RF conditioning Module assembly required 8 Dual RF Modules to implement a 16 channel system, where each channel is fully isolated from others.

The ORBCOMM RF PCI Express card provides packet based communication to a constellation of 27 LEO satellites, and resides in a Dell Linux platform server, along with a Ground Earth Station QAM/OQPSK Modem build by Colmek.

The Wideband On-The-Move TOC RF Mux is used as a test asset for simulating and testing a wide range of networks (e.g., ATM, IP) over satellite links and wireless LANs.

It provided the capability to DC offset the RF and also RF level multiplexing.

The construction is discrete RF components isolated on a common substrate, all contained in a EMI shielding enclosure.

The OTM RF assembly is mounted directly to the HMMWV for on-the-move operation as a Mobile Satellite Ground Terminal. The RF sealed encasement provides the necessary RF EMI isolation while meeting the rugged requirements of the platform.

The enclosure is created out of aluminum sheet metal, to provide the lowest cost packaging, compatible with high volume satellite based applications.

Colmek uses AWR's Microwave Office design suite for design capture and synthesis to simulation, optimization, layout, extraction, and Verification. Its user-experience is incomparable as it integrates powerful, innovative tools and technologies to bring high-frequency designs to life in the shortest time possible and with great flexibility.
