1. A node for use in a broadband distribution network, the node comprising:
a first housing portion that defines a first cavity, the first housing portion having at least one radio frequency (RF) connector port for coupling to a feedline of a broadband distribution network;
a second housing portion that defines a second cavity;
an amplifier disposed in the second cavity of the second housing portion; and wherein:
the first housing portion and the second housing portion are configured to couple together and collectively provide a component cavity therebetween based on the first cavity and the second cavity, and wherein an overall volume V1 of the first cavity of the first housing portion is less than an overall volume V2 of the second cavity of the second housing portion;
the first cavity of the first housing portion defines an upper cavity and a lower cavity; and
a power supply disposed in the first cavity of the first housing portion and an amplifier disposed in the second cavity of the second housing portion, the amplifier electrically coupled to the power supply, and wherein circuitry mounted to an interface plate disposed in the upper cavity provides an electrical passthrough arrangement that is configured to maintain power output to downstream nodes when the amplifier is electrically decoupled from the power supply.
