Abstract
In a low-noise amplifying device, an antenna point is attached to a tip portion of a microstrip line and an end surface of a printed wiring board. The printed wiring board is fixed to a chassis by a screw, a rivet, a projecting portion of a frame or a conductive adhesive in the vicinity of a connection of the antenna pin to the microstrip line. Thereby, even a slight warp that might exist on the board is corrected, so that adhesion between the board and the chassis is reinforced and the low-noise amplifying device stably operates.
