2. Introduction
Congratulations for 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-2000 is a solid state MOSFET VHF-amplifier covering the 144 – 148 MHz
frequency range with a selectable gain of 16-23 db. The internal modulated power limit is
kept to 2200 watts. It’s design is based on Freescale’s rf transistor MRFE6VP61K25H.
Optimized output matching including h3-phase compensation and elliptic low pass filter
ensure 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.
