Abstract (en)
An electrical assembly comprises a board (13) mounted on the bottom wall of an aluminium box (10) and having an insulating layer (16) mounted on a conductive layer (17), a microstrip circuit(18,19,20) formed on the insulating layer (16), and a comb-line microwave filter which includes a set of resonant elements (22 to 25) extending form the conductive layer into a cavity (27). The element (22) is insulated from the conductive layer (17) and is connected to a point in the microstrip circuit. By providing the microstrip circuit and filter on a common board, no connected leads are needed. Other filters may be combined with a microstrip circuit in a similar manner.
