Chapter 1. Overview
General Information
The
Peninsula Engineering Solutions’ RF-8000E Microwave RF Repeater
, hereafter referred to
as the RF-8000E (or
the repeater)
, is a linear, bi-directional, on-frequency RF repeater for microwave
point-to-point networks. The RF-8000E may be used with any manufacturer's compatible 8-GHz radio
operating in the 7.7-8.5 GHz frequency range to provide an intermediate repeater.
Applications
•
Low-cost, highly reliable 8-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 225xDS1 (360 Mb/s),
250xE1 (512 Mb/s), 2xOC-3, 2xSTS-3, 2xSTM-1 (2x155.52 Mb/s), Internet Protocol (512 Mb/s), multiple
video or mixed traffic.
•
Compatible with any manufacturer's 8-GHz FDD radio terminal.
•
Solar and alternative power compatible -- economical in light to heavy routes and remote locations.
Features
•
Power Amplifier RF output power up to +30 dBm, 1.0 Watt.
•
Supports channel bandwidths from 1.25 to 56 MHz.
•
Low Latency, Propagation Delay. 70 ~ 125 nanoseconds, 0.070 ~ 0.125 microseconds per repeater.
•
Power consumption only 34 Watts, solar rated, at +12 VDC for 2-amplifier; higher-power level; duplex
operation.
•
Solar powered, hybrid solar and wind powered, Fuel Cell electric generator 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.
•
Supports Adaptive Modulation and Coding (ACM, AMR) radio terminals.
•
Supports Automatic Transmit Power Control (ATPC) radio terminals.
•
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 175,000 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.
