Patent ID: 6961544

Claim:
A structure of a radio frequency front end comprising as functional units an antenna and at least one bandpass filter and at least one amplifier, in which front end active and passive component parts have been integrated, the structure further comprising: an antenna circuit board having a first surface on which there is at least one radiating element and on a second surface of which there is a conductive plane; a second circuit board having a first surface on which said at least one filter and at least one amplifier are supported, and a second surface of which is conductive; and a protective frame such that the antenna circuit board second surface, the second circuit board first surface and the protective frame form a substantially closed space; wherein the antenna circuit board, the second circuit board with attached units and the protective frame form a single solid component, and the distance between the second circuit board and the antenna circuit board in said component is substantially smaller than a quarter of a wavelength corresponding to any operation frequency of said front end.
