General Information
The
Peninsula Engineering Solutions
’ RF-7000E and RF-7000EL Microwave RF Repeaters
,
hereafter referred to as the RF-7000E (or
the repeater)
, is a linear, bi-directional, on-frequency RF
repeater for microwave point-to-point networks. The RF-7000E may be used with any manufacturer's
compatible 7-GHz radio operating in the 7.1-7.9 GHz frequency range to provide an intermediate
repeater. The RF-7000E is intended for higher capacity applications and the RF-7000EL for low to
medium capacity (< 45 Mb/s) applications.
Applications
Low-cost, highly reliable 7-GHz microwave through repeater for extending range of or clearing
obstructed microwave radio paths.
Excellent performance with digital, or video microwave radios; channel capacity to 2688 PCM (4
DS3 or 180 Mb/s), OC-3, STS-3, STM-1 (155.52 Mb/s), Internet Protocol (200 Mb/s), multiple
video or mixed traffic.
Compatible with any manufacturer's 7-GHz radio terminal.
Solar and wind power compatible -- economical in light to heavy routes and remote locations.
Features
Power Amplifier RF output power up to +30 dBm, 1.0 Watt.
Two RF power levels available, Standard and Higher Power.
Power consumption only 30 Watts, solar rated, at +12 VDC for 2-amplifier, standard-power level,
duplex operation.
Solar powered, hybrid solar and wind powered, ac powered, or other alternative energy electrical
power sources.
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 installations. Suitable for use at unimproved sites anywhere in the world --
Alaska to Saudi Arabia.
Internally protected duplex (FDD), frequency diversity, space diversity and three-way or
"Y junction" system configurations are available.
Only one active element per channel, the internally redundant linear amplifier subsystem.
AGC/ALC provided to correct input fades, regulate output power and reduce overload.
Adaptable to new radio modulations and capacities as technology advances.
RMAS-120 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 1+0 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, photovoltaic modules, battery
charger and batteries.
