Eastern OptX Dramatically Reduces Transmission Line Loss In Ground-To-Antenna Cable Links

Configured as a tower top system, the Model 1200 reduces transmission loss associated with RF cable links

INTERNATIONAL MICROWAVE SYMPOSIUM (IMS) - Eastern OptX announced the Model 1200 low-loss ground-to-antenna tower top system at IMS 2017 recently.

The Model 1200 dramatically reduces the transmission loss associated with RF cable links used in antenna tower connections (up to 40 GHz). Loss improvement per 100 meters at 10 GHz is reduced from 30 dB to 0.03 dB.

Cable connections are often found in radar test systems, cellular, and other communication systems. The main problem presented by loss in the cable connection is the reduction of the signal to noise (SNA) ratio. Eventually the signal drops so far that the receiver can no longer detect it.

The Model 1200 not only reduces signal loss and SNA degradation—it comes as a complete turnkey solution. The system includes cables, antennas, a tower top unit (delay line), a tower base unit (delay line), plus system control.

The system has USB and Ethernet control with DC and AC power options. Custom options are available.

System Description
In a typical system, the Model 1200 System is used as a repeater. The Model 1200 receives the signal transmitted from the radar, converts it for optical fiber transmission. It then relays the signal to the base unit, demodulates, and is stored for later processing. That processing may include target simulation (propagation loss and delay). After processing, the resulting signal is modulated for optical transmission. It is transmitted to the tower top unit, converted back to RF, and transmitted.

Additional system features include tower top gain control, transmit and receive isolation, Doppler generation, multipath interference, and wanted and unwanted interferers.
