Integrated Microwave Technologies To Unveil Nucomm Diversity Receiver

Integrated Microwave Technologies (IMT) will debut its new Nucomm Central Integrated Radome System x6 (CIRAS-x6) at Booth N3922.

Nucomm CIRAS-x6 is a ruggedized COFDM (DVB-T compliant) six-way diversity receiver integrated into a six-segment antenna pod. Its six vertical polarized antennas can handle up to 14 dBi per panel gain. It offers exceptional RF performance in a compact, lightweight IP66-rated weatherproof radome housing, enabling users to mount it on vehicles, towers, building tops or a tripod in any weather condition. CIRAS-x6 also features optional two-channel six-way diversity reception in the same package.

The IMT Nucomm CIRAS-x6 system is designed to optimize the receive signal automatically at all times, virtually eliminating human intervention. In contrast to the older single, highly directional antenna, CIRAS-x6 covers 360 degrees of azimuth with no moving parts. The system sends an MPEG Transport Stream over IP either by Ethernet cable or over ruggedized fiber to a remote decoder. The CIRAS-x6 is powered from a PoE switch or auxiliary DC input.

“IMT is committed to improving operation efficiency with signal acquisition,” says John Payne IV, CTO, Integrated Microwave Technologies. “We are focused on the integration and optimization of the antenna design, use of adaptive digital signal processing (ADSP) and maximal ratio combining (MaxRC) techniques. By combining and optimizing these areas, IMT is able to provide CIRAS-x6, a new class of fully autonomous central receive systems that brings significant value and efficiency to the industry.”

CIRAS-x6 is the next generation of receive systems. Typical diversity receive sites have the antennas, LNAs or BDCs mounted at the top of the tower with coaxial cables running the length of the tower to a receiver and decoder. This design makes the entire system susceptible to lightning and other EMI disturbances. By integrating the receiver into the pod, Nucomm has reduced the coaxial runs from six cables to one.

A Windows-based software application decoder (IMT’s eView) is included with each CIRAS-x6. With a simple click of a button, users can decode video and audio from any COFDM transmitter. eView also features channel control, receiver statistics and recorder functionality.

Designed with the user in mind, CIRAS-x6 requires minimal setup to operate. For advanced functions, such as changing frequency plans, AES decryption keys or unit naming, an easy to use Web-based administration software package is supplied.
