A technique for accommodating electronic components on a multilayer signal routing device is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for accommodating electronic components on a multilayer signal routing device. Such a method comprises determining a component space that is required to accommodate a plurality of electronic components on a surface of a multilayer signal routing device, and then forming at least one signal routing channel on at least the surface of the multilayer signal routing device, wherein the at least one signal routing channel has a channel space that is equal to or greater than the component space.

A tuning circuit (28) for compensating an inter-stage matching network (38) included in an integrated multistage radio frequency (RF) amplifier (22) includes one or more capacitors (30,32) connected in shunt between ground and a voltage supply to the amplifier (22). The capacitors (30,32) have values selected to effectively compensate the inductance from a pull-up inductor (42) included in the inter-stage matching network (38) to provide improved inter-stage matching when inductance and capacitance values of the inter-stage matching network deviate from their desired values due to parasitics and/or when other components, such as input-stage and output-stage transistors of the amplifiers deviate from their pre-fabrication simulation models.

A surface mount adapter (1) for a surface mount device is provided that includes a printed circuit board (3) with a top side (2) and a bottom side (4). The top side includes a footprint (5) for receiving an electrical component (50) and a plurality of input/output lines (26) connected between the footprint and a plurality of first through hole pins (70). The adapter also includes a ground plane (12) and a power plane (13) and is suitable for use with RF and ECL devices.
摘要:
A high frequency bus system (450) which insures uniform arrival times of high fidelity signals to the devices (510), despite the use of the bus (450) on modules (420) and connectors. The high frequency bus system (450) includes a first bus segment having one or more devices (510) connected between a first and second end. The high frequency bus system (450) also includes a second bus segment which has no devices connected to it. The first end of the first segment and the second end of the second segment are coupled in series to form a chain of segments and when two signals are introduced to the first end of the second bus segment at substantially the same time, they arrive at each device (510) connected to the first bus segment at substantially the same time. Conversely when two signals originate at a device (510) substantially at the same time, they arrive at the first end of the second bus segment at substantially the same time. Uniform arrival times hold despite the use of connectors to couple the segments together, despite the segments being located on modules, without the need for stubs, despite the presence of routing turns in the segments and despite the type of information, such as address, data, or control, carried by the signals.
摘要:
The present disclosure relates to embedding a power modification component such as a capacitance or a resistance inside of pads that are located to extend over and beyond the vias of the PCB so that a portion of the pad containing the embedded capacitance or resistance is located beyond where the vias or blinds are located. Each of the pads will include an opening that is located over a given one of the vias or blinds to permit that via to conduct through the opening. In this way the capacitance and the resistance will have a closer contact point the electrical component.
