The Anttron AM124 is a wideband CATV amplifier designed for CATV installations carrying both digital and analogue channels. Its die-cast aluminium chassis and GaAs-MMIC transistor produce a compact unit with high linearity and efficiency. The AM124 differs from the A181 model with its higher 40 dB forward gain and the addition of a -30 dB test input/output port.

The amplifier provides separate forward-path gain adjustment, slope adjustment, and return-path gain adjustment. The attenuation range covers 0–18 dB for both paths, while the slope attenuation range on the forward path is 0–15 dB. Noise figure remains below 7 dB throughout the operating range.

Key Features

• 1 input, 1 output
• Test input/output: yes, -30 dB
• Forward gain (85–862 MHz): 40 dB
• Return path gain (5–65 MHz): 10 dB
• Attenuation range (forward and return path): 0–18 dB

Product Benefits

• 40 dB forward gain covers longer cable runs and larger distribution networks compared to lower-gain CATV amplifiers
• The -30 dB test port allows signal level monitoring during installation and maintenance without interrupting service
• Separate forward and return path gain controls enable optimisation of both downstream video and upstream data paths in two-way networks
• GaAs-MMIC technology delivers a maximum output of 118 dBµV with a noise figure below 7 dB, preserving signal quality to the subscriber
• 6 W power consumption allows always-on operation with minimal energy cost
