摘要： Disclosed is a high frequency (HF) amplifier to be used at a high frequency, typically in the range of 9 GHz to 12 GHz, in which coupling of input side and output side is prevented to achieve high gain without influence on the fidelity of amplification. The HF amplifier comprises a metal case consisting of a box type container and a lid, an amplifying element installed on a dielectric, insulating board at the bottom of the case, and leads connected to the input circuit and the output circuit of the amplifying element and extending outside through both the end walls of the case. The HF amplifier is characterized by disposition of an electromagnetic wave-absorbing sheet or sheets inside of at least one of both the side walls, the ceiling, and both the end walls so as to prevent electromagnetic coupling.

摘要： An object of the present invention is to provide a shielding sheet which has a high and stable shieldability to electromagnetic waves, has a sufficient pliability, and can be easily wound around a cable and the like. The shielding sheets 1, 1', and 1" each having a pliable insulating layer 2, a powder layer 3 in which a powder 4 made of soft magnetic metal or alloy, having an average particle diameter of less than 100 .mu.m, is buried in layers along at least one surface of the insulating layer 2 and/or at the midpoint position along the thickness direction. It also includes a shielding sheet 1a in which a powder 4 is distributed in the middle portion 5 of the insulating layer 2 at the ratio of less than 70% by volume to the powder layer 3, 3 along both surfaces. Furthermore, shielding sheets 1, 1a, 1', and 1", in which a powder 4 of the powder layer is flat shaped, the aspect ratio being more than 2, and the powder is buried in a manner that the longer diameter direction of the powder is almost along the plane surface direction of the insulating layer 2, are also included within the scope of the present invention.
