摘要： An electronic device may include a transceiver with a substrate and an inductor on the substrate. A ring of ground traces may surround the inductor. Circuit components may be patterned onto the substrate overlapping the inductor, a region of the substrate surrounded by the inductor, and/or a region of the substrate between the inductor and the ring. The components may be arranged in trees with feed lines extending radially outward from a central axis. The components in each tree may be separated from the capacitors in other trees by gaps, preventing eddy currents on the trees. The components may be used to form bypass capacitors for power supply lines, a low-dropout regulator load, part of the loop filter of a phase-locked loop, or other portions of the transceiver. The components may thereby be used to convey signals while also meeting fill factor requirements associated with fabrication of the substrate.

摘要： An oven controlled crystal oscillator consisting of heater-embedded ceramic package includes a substrate, a crystal package, a crystal blank, a metal lid, a first IC chip, and a cover lid. The crystal package is mounted on the substrate, and a central bottom of the crystal package is provided with the first IC chip. The crystal blank is mounted in the crystal package and sealed by the metal lid. The crystal package has an embedded heater layer establishing a symmetric thermal field with respect to the first IC chip and the crystal blank. Alternatively, a heater-embedded ceramic carrier substrate is arranged between the first IC chip and the crystal blank to establish a symmetric thermal field with respect to the first IC chip and the crystal blank. The cover lid is combined with the substrate to cover the crystal package and the metal lid.

摘要： An oscillator assembly including an oscillator seated on a pad of thermally conductive material formed on the surface of a printed circuit board and covered by a lid defining an oven for the oscillator. In one embodiment, a plurality of heaters are located on different sides of the oscillator and at least partially seated on the pad for evenly transferring heat to the pad and the oscillator. In one embodiment, the oscillator is a temperature compensated crystal oscillator and an integrated amplifier controller circuit on the printed circuit board integrates at least one operational amplifier for controlling the heater(s) and one or more transistors for providing heat to the oven. A canopy seated on the pad and covering the oscillator can be used for transferring heat more evenly to the oscillator. A cavity in the bottom of the printed circuit board defines an insulative air pocket.

摘要： The inventive shock damping system for vibration sensitive surface mounted devices consists of an elastomeric material having conductive fiber material disposed between a printed circuit board (PCB) and a surface mounted device. Once disposed between PCB and surface mounted device, the elastomeric material, the PCB and the surface mounted device are compressed together with a component restraining system, to provide a secure electrical connection between one or more interconnect pads conductively attached to surface mounted device and the PCB. The elastomeric material allows signals and current to flow between surface mounted device and PCB without the use of any attached wires or leads while at the same time providing a system for damping any shocks or vibrations that may be transferred to surface mounted device through the PCB or through the protective component restraining system that encloses the device and the elastomeric material.
