Congratulations on purchasing your new BEKO linear amplifier. You have purchased a
quality product, individually built to the highest standards, and one that will last you a
lifetime. Please take a few minutes to read this instruction manual and then store it in a safe
place for future reference. Finally, it's up to you to insure that all components used in your
system such as cables, connectors, preamps and coaxial relays can handle this amplifier's
power level.
The HLV-550 is a solid state MOSFET UHF-amplifier covering the 430 – 440 MHz
frequency range with a selectable gain of 13-20 db. The internal modulated power limit is
kept to 650 watts. It's design is based on Freescale's rf transistor MRFE6VP6300H. The
optimized output matching with low pass filter insure best efficiency, highest 1dB
compression and high spectral purity. It is essential that the driving source has a narrow phase
noise and high spectral purity. The output signal of an amplifier can't be better than it's input
signal.
