Applications
Low-cost, highly reliable 2 GHz microwave through repeater for extending range of or clearing obstructed microwave radio paths.
Excellent performance with analog, digital, or video microwave radios; channel capacity to 1200 FDM, 1 DS3, 45 Mb/s PCM,
34 Mb/s PCM.
Compatible with any manufacturer's 2 GHz radio terminal.
Solar power compatible -- economical in thin routes and remote locations.
Features
Two RF output power level available: +24/+28 dBm analog, +18/+22 dBm digital.
Power consumption only 2.2 amperes at 12 Vdc for regular-power duplex operation.
Solar powered, ac powered, or powered by primary cells.
Compact and lightweight -- ideally suited for remote sites that do not have access roads or commercial power.
Environmentally protected aluminum, weathertight, lockable cabinet. No extra environmental shelter required in most installation.
Suitable for use at unimproved sites anywhere in the world -- Alaska to Saudi Arabia.
Internally protected duplex, frequency diversity, and three-way or "Y junction" configurations available.
Only one active element per channel, the internally redundant linear amplifier.
AGC/ALC provided to correct input fades and reduce overload.
Maximum gain can be field-adjusted for easy fine-tuning.
In the case of single duplex configuration, amplifiers can be replaced without disrupting service.
RMAS-110 Alarm system (optional) can remotely monitor repeater.
Equipped with directional couplers for in-service RF output power measurements.
No frequency conversion -- received signal is filtered, amplified, and re-radiated.
Very reliable, greater than 85,000 hours MTBF for duplex.
Available as a self-contained RF repeater for use with customer-furnished antenna and power equipment or as a complete package
including repeater, antenna, solar electric panels, battery charger, and batteries.
