LCM-550x12
55 to 870MHz DISTRIBUTION AMPLIFIER
3) OPERATION
The LCM-550x12 amplifier is the designed to operate at +45 dBmV out with 12 channels. Measure the
direct output of the amplifier with a spectrum analyzer or signal level meter. Adjust the output level controls
on the individual modulators for your desired operational levels. Exceeding the specified +45 dBmV
maximum output level (12 channels) may cause systems distortion levels to exceed acceptable levels. If all
of your desired carrier levels are below +41 dBmV, Olson Technology suggests that you use a fixed
attenuator pad between the combiner output and the amplifier input. Use a 3dB pad for maximum outputs
of 35-41 dBmV, a 6dB pad for 35-38, etc. Once the output levels are set, the amplifier may be connected
to its intended use and levels at its test point maybe measured and recorded for referance. If the amplifier
test point is used as a output, be sure that the main output is terminated in 75
Ω.
