LOW NOISE DISTRIBUTION AMPLIFIER, 1-50 MHz
The LNDA-15RM Isolation Amplifier is an economical Low Noise Distribution Amplifier with AC and DC operation capabilities. The Amplifier is designed for maximum flexibility in a 19 inch rackmount 1U enclosure and may contain up to three RF signal distribution modules. Each module accepts one RF input with a frequency range of 1-50 MHz and provides five isolated outputs. All outputs are AC coupled and the grounds are DC isolated to reduce the effect of ground loops. The channel-to-channel and reverse isolation are greater than 95 dB providing ample protection for the signal source and downstream users.
All output power levels are monitored and compared to a preset threshold of +7dBm to provide the user with a visual condition of the RF signal through a monitor LED located on the front panel.
The LNDA-15RM may be customized by selecting the number of inputs and/or outputs as well as the DC operation capabilities as shown in the option section.
