    Abstract: An RF circuit module, in which a power amplifier and a transceiver are united, with reduced interference between its electronic circuit blocks, downsized and still having high performance, and with a stable performance not dependent on the ground land structure on the motherboard, is provided. The ground plane 110 for at least a last-stage amplifier 11 of the power amplifier 10 where the greatest power is generated in the whole RF circuit block, that is, the source of generating the greatest noise and heat for the RF circuit block, is isolated from the ground plane for at least one circuit portion of the transceiver 9 including an LNA 51, receiver 52, transmitter 30, and VCO 70. These ground planes are connected to a common ground plane 480 through different connection conductors, respectively.

    Abstract: A method for manufacturing a mid-plane. a multi-layer board having a connection assembly is provided and a dielectric layer with a channel formed therein to define a perimeter of a connector area is provided. The dielectric layer is bonded to the multi-layer board such that the connector area overlaps the part of the connection assembly of the multi-layer board. At least a portion of the connector area in the dielectric layer is removed to expose the connection assembly of the multi-layer board. A rigid multilayer is also disclosed. The rigid multilayer includes a multi-layer board and a dielectric layer. The multi-layer board has a connection assembly. The dielectric layer has a channel formed therein to define a perimeter of a connector area. The dielectric layer is bonded to the multi-layer board such that the connector area overlaps the connection assembly of the multi-layer board. The connector area can then be removed such as by depth controlled routing. As will be understood by one skilled in the art, the depth tolerance is not critical because the dielectric layer is pre-formed with the channel prior to formation of the rigid multi-layer.

    Abstract: The invention relates to a filter arrangement for separating radio frequency energy from signal energy in a signal line. The signal line extends at least partly in a first layer of a multi-layer printed circuit board. A grounded surface is arranged in a second layer of the printed circuit board. The signal line to be filtered is interrupted in the first layer in the filter region and continued in a third layer, the second and the third layers being located on opposite sides of the first layer. Due to the skin effect the radio frequency energy will be concentrated on the side of the signal line facing the grounded surface. The side of the signal line remote from the grounded surface is then to a large extent decoupled from radio frequency energy, such that the actual signal path can be continued without being disturbed by radio frequency energy.
