E-RF Wireless
This series of continuous-duty base station, link transmitter and specialized mobile radio power amplifiers are designed to operate with any FCC-type accepted exciter. They also may be combined with optional plug-in control boards and exciter to provide a complete base station, link transmitter or SMR application in the same package as the power amplifier. All feature a small footprint that allows easy deployment in most existing cabinets. They are available in 72, 150, and 450 MHz versions with power levels from 50 W to 500 W depending on frequency.
