ABSTRACT:
An adjustable directional coupler including a housing, a first connector and a second connector secured to the housing, and a main transmission line extending through the housing and between the first and the second connectors. The main transmission line has a center conductor coaxially surrounded by an insulator. A circuit board is secured within the housing, with a first edge of the circuit board being generally parallel to the main transmission line and the circuit board being transversely adjustable with respect to the main transmission line. At least one auxiliary line is mounted on the circuit board and includes a pick-up link extending from a network juncture. The pick-up link is adjacent to and parallel with the first edge of the circuit board. A third connector is also secured to the housing. Preferably, the coupler further comprises a heat conductor mounted on the circuit board, in contact with the housing, and the auxiliary line includes a termination resistor connected to the pick-up link and mounted on the heat conductor.
