30W POWER AMPLIFIER
(1/2 X 19”/2U STANDARD-RACK)
The RPA25 Power Amplifier is very compact and, in spite of its small size, it features appreciated and unique characteristics.
Its inherent noise is extremely low and thanks to the very sharp output low-pass filter, also the amplified noise eventually generated by the transmitter/exciter is kept to a minimum.
The RPA25 allows to operate also with output mismatching: in case of bad antenna or cable-impedance characteristics, the amplifier is not shut-off (as the most part of less-performing amplifiers) but instead the reflected-power coming from the antenna is redirected, by the built-in output-isolator, to its internal dummy-load. This prevents the overloading of the final power-stage and in this way even any intermodulation product and/or noise generation are avoided.
The apparatus can be powered by a wide range of DC powering-voltages, without reducing performances, thanks to the built-in very high-efficiency dc/dc power converter.
