摘要： The invention discloses an RF ASIC, (100), which comprises first (110) and second (130) plane conductors arranged parallel to each other with an isolating material (120) of a certain thickness (d) between them, and a ground plane (150) arranged in parallel to said conductors and at a certain distance (h) from the nearest conductor. Each conductor (110, 130) is shaped as a rectangle with a width (W) and a length (L) such that the length exceeds the width, so that each conductor has opposing short sides and opposing long sides. Each conductor exhibits a connector (1, 2, 3, 4) at each of its short sides, and the ASIC can be used as a transformer by using the connectors (1, 2) on one opposing short side as input ports to the transformer, and the connectors (3, 4) on the other opposing short side as output ports.

摘要： An isolated converter with a reduced size is disclosed. A small-sized multilayer sheet transformer includes a multilayer circuit board composed of a plurality of sheet substrates, coil patterns of primary and secondary coils disposed coaxially on the sheet substrates, and a core member disposed in a coil pattern unit formed of the coil patterns. In this multilayer sheet transformer, a coil pattern formed on the outer surface of the top layer and a coil pattern formed on the outer surface of the bottom layer are for the same coil on either the primary or secondary side. In the case where the coil patterns formed on the outer surfaces of the top and bottom layers of the multilayer sheet transformer are for the primary coil, an isolation gap is formed between the multilayer sheet transformer and a circuit on the secondary side to prevent an electrical breakdown between the primary and secondary sides. In the case where the coil patterns formed on the outer surfaces of the top and bottom layers of the multilayer sheet transformer are for the secondary coil, an isolation gap is formed between the multilayer sheet transformer and a circuit on the primary side to prevent an electrical breakdown between the primary and secondary sides.
