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 these instructions manual and then store it in a safe place for
future reference. Finally it's up to you that all components used in your system as cables,
connectors, preamps and coaxial relays can handle this power level.
The HLV-350 is a solid state LDMOSFET SHF-amplifier covering the 1275 – 1300 MHz
frequency range with a selectable gain of 17 db. The internal modulated power limit is kept to
500 watts. It's design is based on NXP's rf transistor BLF6G13L-250P. Each of the two
amplifier blocks is protected by a separate circulator before final 2:1 combining. This insures
high ruggedness and independence on any load mismatch as well as high linearity and
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.
