Applications
Low-cost, highly reliable 4-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 1800 FDM, 1920 PCM(14OMb/s)
or multiple video.
Compatible with any manufacturer's 4-GHz radio terminal.
Solar power compatible -- economical in thin routes and remote locations.
Features
RF output power up to +25 dBm analog and FSK, lower power for digital.
Power consumption only 2.5 amperes at 12 Vdc for 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.
Duplex frequency diversity, multi- RE channel 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.
Amplifiers can be replaced without disrupting service.
RMAS-l20 Alarm system (optional) to remotely monitor repeater.
Provided with directional couplers for in-service RE output power measurements.
No frequency conversion -- received signal is filtered, amplified, and re-radiated.
Very reliable, greater than 85,000 hours MTBF for duplex.
Approved for use with 4-GHz radio systems.
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.
Steel, weatherproof, lockable cabinet. No environmental shelter required in most instaflations.
