Narrow band high power amplifier for CATV infrastructure
The MHW1254LN is a narrow band high power amplifier designed for CATV applications, built into a chassis-mount module. This is not a broadband drop amplifier — it targets a specific narrow frequency band for high-power line driving in cable television headend or distribution nodes. The single-circuit module draws 115 mA from the supply rail, a figure to budget for when sizing the local regulator and thermal management in the node enclosure.
Chassis mount module — mechanical and thermal integration
Packaged in a 7-CATV module with chassis-mount provisions, the MHW1254LN is meant to bolt directly to a heatsink or cold plate. The module format includes the RF matching and bias circuitry internally, so the board-level design is reduced to providing a clean DC supply and RF connectors. The chassis-mount interface carries the heat, not the PCB copper — ensure the mounting surface is flat and thermally conductive to keep the module within its operating range.
